The converter electronics of the measurement systems of the type discussed are usually formed by means of one or more microprocessors and / or one or more digital signal processors, and are also regularly configured to be electrically connected to a superior electronic data processing system (EDP), such as formed by means of a programmable logic controller (PLC) and / or a process control system (PCS) and / or an edge (computing) device and / or a cloud (computing) system, for example for transmitting the (measurement system) data collected by means of the measurement system and / or for remote control and / or for power supply.

[0003] The measurement systems in DE-A102021105397, DE-A102019009024, DE-A102020112154, DE-A102020114519, DE-A102020118702, DE-A102020127356, DE-A102020131452, DE-A102020132223, DE-A102020132685, DE-A102020132686, DE-A102020132986, DE-A102020133566, DE-A102020133614, DE-A1020133851, WO-A2019 / 017891, WO-A2021121867 are in particular modular vibration measurement systems (formed by means of vibration sensor modules). In each case, at least the basic module of the modular vibration measurement system shown in DE-A102021105397, DE-A102020112154, DE-A102020114519, DE-A102020127356, DE-A102020131452, DE-A102020132223, DE-A102020132685, DE-A102020132686, DE-A102020132986, DE-A102020133566, DE-A102020133614, DE-A102020133851, WO-A2019 / 017891 or WO-A2021121867 has a (protective) housing which has at least one chamber at least partially enclosed by a housing wall and one or more electrical coils, for example cylindrical and / or configured as air coils, which coils (spaced apart from one another) are placed in the chamber of the (protective) housing and are at least indirectly mechanically connected to the housing wall. Each coil is also electrically connected to converter electronics. The converter electronics can be at least partially accommodated inside the (protective) housing and / or at least partially accommodated outside the (protective) housing, for example in a separate electronics housing. In particular, the basic module is also configured to receive the sensor module of the measurement system and to be mechanically firmly connected thereto (to form a vibration-type measuring transducer), but still releasably re-connectable, in particular to form the vibration measurement system itself; this is also done in particular in such a way that the sensor module is locked in the basic module or cannot be moved.

[0004] As already mentioned, the sensor module of the corresponding measuring system is also configured to be replaceable, and in particular in the aforementioned modular vibration measuring system in such a way that it can be introduced into the chamber from outside the (protective) housing of the basic module or through the (insertion) opening of the housing provided in the housing wall, and that it can be removed again from the basic module without damage, possibly without tools, in particular from outside the housing and / or through the (insertion) opening of the housing, or without having to dispose of or remove the basic module itself from the corresponding (process) plant. In particular, this also allows the sensor module to be subsequently inserted on-site, i.e., into an already installed basic module, or to replace a defective or worn sensor module on-site with a complete new sensor module, which can be used only once or only for a predetermined period of time ("disposable").

[0005] The sensor module of the modular vibration measurement system of the aforementioned type also has one or more (e.g., cylindrical) permanent magnets and is also configured to be mounted in the base module such that each permanent magnet is placed within the aforementioned chamber but still spaced apart from the housing wall, in particular such that each permanent magnet remains in a static mounting position which is predetermined in each case with respect to the alignment with and / or the minimum distance from one of the electric coils in the base module, and such that the corresponding imaginary longitudinal axis of each permanent magnet and the imaginary longitudinal axis of at least one of the electric coils are aligned with each other or extend parallel to each other. In the aforementioned vibration measurement system, each sensor module also has at least one (measurement) tube, e.g., at least partially straight and / or at least partially curved, wherein the tube wall forms the outer shell surface of the tube, particularly made of metal or plastic material, and has an inner cavity wound by the same tube wall, particularly two substantially identical parallel (measurement) tubes, and each of the aforementioned permanent magnets is fixed to the outside of the tube wall, particularly to the central section of the tube wall extending between the end of the first section and the second section remote therefrom, particularly by a material-bonding connection to the tube wall. Additionally, the sensor module or at least one of its (measurement) tubes is configured to be mounted in the housing, if necessary without tools, such that the tube is at least partially, particularly completely, placed within the chamber but still spaced apart from the housing wall, and each permanent magnet in the corresponding mounting position forms a voice coil together with the corresponding electric coil, particularly serving as an electro-dynamic oscillation exciter, and / or a plunger coil, particularly serving as an electro-dynamic oscillation sensor. In the case of an at least partially curved (measurement) tube, the aforementioned central section can be, for example, substantially U-shaped or V-shaped. In such a modular vibration measurement system, each of the aforementioned (measurement) tubes is also configured to carry a fluid measurement substance flowing within the tube lumen during operation, particularly with a predetermined flow direction and / or having a flow direction pointing from the end of the first section to the end of the second section, and is simultaneously vibrated in order to generate a measurement effect related to one or more measurement variables of the measurement substance, particularly such that the central section performs an oscillatory motion with respect to the static rest position and / or the (measurement) tube is driven by means of at least one of the aforementioned (energized) oscillation coils and / or a (AC) voltage representing the oscillatory motion of at least one tube and thus serving as an oscillation signal is generated by means of the aforementioned plunger coil.The transducer electronics of such a measurement system are then correspondingly configured to feed electrical power into at least one electrical coil forming the aforementioned voice coil by means of an electrical drive signal (in particular having an applied alternating current and / or an applied (alternating current) frequency substantially corresponding to the resonance frequency of at least one tube) and / or to determine, in the case of a measuring device configured as a Coriolis mass flowmeter or a measuring device configured as a Coriolis mass flow / density measuring device, a measured value of one or more measured variables of the measured material flowing through one or more (measurement) tubes, for example, to generate a (mass flow) measured value representing the mass flow based on the (measured) phase difference between two of the aforementioned oscillation signals and the phase difference of a measured value characteristic function set in the transducer electronics. The phase difference to the mass flow characteristic function can be, for example, a (linear) parametric function having a (scale) zero point corresponding to the (measured) phase difference of two oscillation signals that can be measured when the measured material is at rest or when the mass flow is zero, and having a slope corresponding to the (measured) sensitivity of the measurement system or the change in the (measured) phase difference associated with the change in the mass flow. Since the one or more resonance frequencies of at least one tube also depend, in particular, on the instantaneous density of the corresponding measured substance, it is thus possible, by means of such a measurement system, to directly measure, in addition to the mass flow, the density of the corresponding measured substance flowing through it by means of the (alternating current) frequency of the drive signal and / or by means of the (signal) frequency of at least one of the oscillation signals. The transducer electronics of the measurement system of the type discussed are therefore generally also equipped to generate a (density) measured value representing the density based on the aforementioned (alternating current) frequency of the drive signal and / or based on the corresponding signal frequency of at least one of the oscillation signals, for example using a characteristic curve function correspondingly configured in the transducer electronics. In addition, for example, based on the excitation energy or excitation power required to maintain the useful oscillation and / or based on the damping of the excitation (resonance) oscillation caused by the dissipation of the oscillation energy or by using a damping-measured value characteristic curve function correspondingly set in the transducer electronics, it is also possible to directly measure the viscosity of the medium flowing through by means of the vibration measurement system of the type discussed. Additionally, it is possible to easily determine additional measured variables derived from the aforementioned flow and / or material parameters such as the Reynolds number by means of such a vibration measurement system.

[0006] In order to simplify the commissioning of a modular measurement system, in particular of at least a modular vibration measurement system, the sensor module can also have at least one identification element which bears information relating to or identifying the same sensor module, such as a bar code, a QR code or a radio tag (RFID-TAG) attached to at least one tube, and / or the base module can have at least one light-emitting semiconductor element which is positioned inside the (protective) housing and is connected to the converter electronics, such as a light-emitting diode (LED), and / or one or more radio transmitters / receivers (RF transceivers) and / or light sensors, such as one or more CCD light sensors and / or one or more CMOS light sensors, each light sensor being positioned inside the (protective) housing and being connected to the converter electronics.

[0007] Measurement systems of the type under discussion, in particular modular vibration measurement systems, must also regularly check their functional efficiency or any deviation from a predetermined corresponding reference state, for example in the state determined by the manufacturer or the manufacturer's factory and / or during on-site calibration or commissioning of the corresponding measurement system, for example in order to be able to detect as early as possible any reduction in the function or measurement accuracy of the measurement system associated with an increasing deviation from the reference state, with which reduction the measurement system ultimately maps the measurement variables to be recorded, in particular the mass flow and the density, into the corresponding measured values. Such a reduction in the function or measurement accuracy of such a measurement system can occur, for example, in the form of a mainly irreversible change in the electrical impedance of the above-mentioned swing coil and / or plunger coil, and / or in the form of a permanent reduction in the stability of the mechanical connection between the base module and the sensor module or the positioning accuracy of the sensor module in the base module, or can be caused, for example, by thermal and / or mechanical overload, such as due to very high or very low temperatures, ageing, increased or condensed moisture in the base module and / or wear of the components of the base module caused by frequent replacement of the sensor module. Other influencing factors which at least indirectly and / or at least temporarily impair the function of the measurement system include multi-frequency and / or high-frequency electromagnetic (external) radiation or fields (EMC) propagating in the base module or (external) sound waves propagating in the base module, for example in the form of structure-borne sound.

[0008] Therefore, it must regularly be assumed that one or more of the system functions (transfer functions) inherent in the measurement system are also changed compared to the (reference) system functions inherent in the corresponding original measurement transducer, and each of the system functions (transfer functions) inherent in the measurement system characterizes the functional dependence of the aforementioned oscillation signal on the corresponding drive signal or the functional dependence of the oscillation signal on one or more of the corresponding flow rate and / or material parameters of the drive signal and the measurement substance. Examples of such system functions of the vibration measurement system include the mass flow rate to phase difference system function, according to which the aforementioned (measurement) phase difference of the oscillation signal depends on the mass flow rate, or the density to resonance frequency system function of the measurement transducer, according to which the resonance frequency of one or more of the at least one tube depends on the density of the material to be measured. Therefore, also affected by such (over)loading of the measurement transducer is the measurement function of the measurement system involving the aforementioned system function, according to which the measurement system as a whole converts the corresponding measurement variable to be recorded into a corresponding measurement value, for example, a characteristic curve function composed of the following functions, the aforementioned mass flow rate to phase difference system function and the phase difference to mass flow rate measurement value characteristic curve function, that is, the characteristic function implemented in the converter electronics, according to which the determined phase difference is converted into a mass flow rate measurement value, the mass flow rate to measurement value measurement function of the measurement system, according to which the thus determined mass flow rate measurement value depends on the mass flow rate. The phase difference to mass flow rate measurement characteristic curve function can be, for example, a (linear) parametric function having a (scale) zero point corresponding to the (measurement) phase difference measured at rest and a (measurement) sensitivity corresponding to the change in the (measurement) phase difference associated with the change in the mass flow rate (the slope of the characteristic curve function). Further examples of such system functions (which are also potentially affected by the interference or measurement functions formed with them) can include the density to resonance-frequency-system function of the measurement transducer involved in such a case or the density to measurement-value-(measurement) function of the measurement system, as well as the resonance-frequency to density-measurement characteristic function of the converter electronics involved in such a case and / or the viscosity to damping-system function of the measurement transducer or the viscosity to measurement-value-(measurement) function of the measurement system, and the damping to viscosity-measurement characteristic function of the converter electronics. Therefore, in the case of a linear parametric function (e.g., its zero point and / or its slope), the change in the corresponding system function can have, for example, the effect of a drift of one or more of the corresponding characteristic curve parameters of one or more of the aforementioned characteristic curve functions. The above possible and sometimes irreversible changes to one or more of the system or measurement functions of the measurement system can sometimes also cause the measurement system as a whole to operate incorrectly to the extent that the high measurement accuracy targeted in such typical measurement systems is no longer guaranteed, which means that the function of the measurement system is significantly impaired, possibly even suspended, or there is a corresponding critical failure of the affected measurement system.

[0009] Taking this into account, measurement systems of the type under discussion are generally subjected to corresponding (re)checks, for example at regular intervals during a scheduled or predictive maintenance run; such that the functionality of the sensor module or the entire measurement system is checked on-site during a time-controlled (self-)diagnosis run performed with the measurement system and / or triggered by corresponding control commands transmitted to the converter electronics, in order to be able to initiate, if necessary, appropriate repair or replacement measures as quickly as possible, for example when a fault in the measurement system is detected. In the case of a modular (vibration) measurement system of the type under discussion, such (repair or replacement) measures regularly involve replacing a defective sensor module with a (completely) new sensor module, which can also be carried out quickly and easily on-site. However, a disadvantage of the test procedure in this way is that only the functionality of the measurement system as a whole can be verified, or conversely, any detected fault cannot be precisely located within the measurement system, i.e., assigned to the basic module, the sensor module or the converter electronics. In particular, it is not easy to identify faults in the basic module or its converter electronics that only impair the measurement accuracy using such (self-)diagnosis, such that the need to replace the basic module and / or the converter electronics can also be determined during such an inspection run of a measurement system of the type under discussion. Summary of the Invention

[0091] For on-site operation of the measurement system or for displaying the data (measurement and / or operation) generated by the measurement system, especially the measurement values of at least one measured variable and / or the (status) messages of the measurement system, the measurement system can also include a display or a display and an operating element HMI, which is electrically connected to the transducer electronics, such as formed by a touch display, and / or can use an external (field) operating device, which is (only temporarily) connected to the transducer electronics, such as connected to its aforementioned data input and / or its aforementioned data output.

[0092] The sensor module M2 (when installed or during operation of the measurement system) is mechanically (permanently) connected to the base module M1 and is also coupled to the converter electronics in terms of signal technology; this is done in particular in such a way that the sensor module M2 has been mechanically connected to the base module M2 on-site, for example without tools, and / or such that the sensor module M2 can be detached (non-destructively) from the base module M1. The base module M1 and the sensor module M2 can also advantageously be provided or configured such that the sensor module M2 can also be used on-site, i.e. (subsequently) in the base module that has already been installed (in the factory), which means that the corresponding measurement system can also be created by assembling the base and sensor modules on-site, for example without tools and / or without having to handle the base module M1 itself or remove it from the corresponding (process) plant. As is obvious, the base module M1 can also advantageously be configured to receive the sensor module M2 and connect to it in a mechanically fixed but releasable manner, such that the sensor module M2 is held or locked immovably in the base module M1. According to another embodiment of the invention, the sensor module M2 and the base module M1 are also configured to be detached again without tools, in particular on-site, in particular non-destructively, in particular such that the sensor module can be removed again from the base module M1 without having to handle the base module M1 itself or remove it from the corresponding (process) system. Thus, it is now particularly possible to easily replace a defective or worn (old) sensor module on-site with a complete new sensor module (M2), which can be used for only a limited number of batches or only once and / or only for a predetermined period of time ("single use", "disposable"). Thus, the formation of the measurement system or the (re-)commissioning of the measurement system, for example, can also (immediately) include the (mechanical) connection of the sensor module to the base module (installed in the aforementioned plant), for example, i.e. by inserting or installing the sensor module into the base module, and the integration of the sensor module into the aforementioned pipeline system for guiding the flowing fluid (measurement) medium, for example, also (immediately) before connecting to the base module.

[0093] According to another embodiment of the present invention, the basic module M1 has a (protective) housing 11, which (protective) housing 11 has at least one chamber 11* (for the sensor module M2), the chamber 11* is at least partially wrapped by the housing wall 11+, and the sensor module M2 is configured such that it can be introduced into the chamber 11* of the (protective) housing 11 from the outside of the (protective) housing 11 and / or through an (insertion) opening provided in its housing wall 11+; for example, as already mentioned, this is the case without having to handle the basic module M1 itself or remove it from the corresponding (process) plant. Advantageously, the basic module M1 and the sensor module M2 can also be configured such that the sensor module M2 can be removed from the basic module M1 by being removable from the outside of the housing 11 and / or through the (insertion) opening of the (protective) housing 11, in particular non-destructively and / or without tools, for example without having to handle the basic module M1 itself or remove it from the corresponding (process) system. If required, the aforementioned (insertion) opening of the housing 11 can also be sealed by means of a suitable cover after the installation of the sensor module and / or after its disassembly, for example also dust-proof and / or sealed against large water jets and / or explosion-proof. In addition to the sensor module, the modular converter electronics ME can also be at least partially accommodated in the chamber 11*. Alternatively or additionally, the converter electronics ME can also be at least partially accommodated outside the chamber 11*, for example in the additional electronics chamber 100 of the basic module M1.

[0094] To support the correct installation of the sensor module M2 into the basic module M1, the sensor module M2 and the basic module M1 can each have corresponding guiding structures or elements, such as corresponding (guiding) grooves in one of the two modules (M1, M2) and (guiding) springs and / or (guiding) pins in the other of the two modules that slide therein during assembly. To simplify the (field-completed) commissioning of the measurement system, the sensor module M2 can also have at least one (information) storage element 28, such as a bar code, a QR code, or a radio tag (RFID tag), which carries information related to or identifying the sensor module M2. Advantageously, the basic module M1 that additionally reads the (information) storage element 28 can have at least one light-emitting semiconductor element 19a (in the direction of the sensor module) connected to the converter electronics, such as a light-emitting diode (LED), and / or one or more radio transmitters / receivers (RF transceivers) and / or a light sensor 19b connected to the converter electronics, such as one or more CCD light sensors and / or one or more CMOS light sensors.

[0095] The sensor module M2 of the measurement system according to the invention (connected to the basic module M1 and optionally integrated into the aforementioned line system) is in particular configured to be in contact with a fluid medium, such as the aforementioned measurement medium or a calibration medium (for calibrating the measurement system), for example bypassed or passed through by the fluid medium, and during this time to set or change at least one (signal) parameter of at least one electrical (for example capacitive or inductive) measurement signal, such as electrical (signal) voltage, electrical (signal) current, (signal) frequency or (signal) phase, which measurement signal is applied to the (first) (measurement) signal input of the converter electronics according to at least one measurement variable of the medium (in each case in contact with the sensor module); this is done, for example, in such a way that at least one measurement signal follows the change in at least one measurement variable, where the proportional change in at least one signal parameter is within a predetermined measurement range. Thus, the sensor module can be formed, for example, by means of a rod probe that can be introduced, for example, into the aforementioned pipeline according to DE-A102008029956. Alternatively, the sensor module can also be formed by means of one or more (measurement) tubes that can be introduced into the path of the aforementioned line or bypass line, so that the sensor module can also correspond to one of the (vibration) sensor modules shown in the initially mentioned WO-A2019 / 017891, WO-A2021121867, WO-A2022 / 242975, DE-A102021105397, DE-A102020133614, DE-A102020132685, DE-A102020133851, DE-A102020133566, DE-A102020132986, DE-A102020132686, DE-A102020132685, DE-A102020131452, DE-A102020132223, DE-A102020127356, DE-A102020114519, DE-A102020112154, DE-A102019009024, DE-A102020118702 or DE-A102008029956 or also shown in the (not yet published) international patent application PCT / EP2022 / 076349.According to another embodiment of the invention, the sensor module M2 accordingly has at least one (first) tube 31, which at least one (first) tube 31 has a tube wall forming the outer shell surface of the tube 31, for example made of a metal or plastic material, and has an inner cavity 21* enclosed by the same tube wall, and / or the sensor module M2 is further configured to set or change at least one (signal) parameter of at least one electrical (for example capacitive or also for example inductive) second measurement signal, such as electrical (signal) voltage, electrical (signal) current, (signal) frequency or (signal) phase, the second measurement signal being applied to a second (measurement) signal input of the converter electronics according to at least one measurement variable of the medium (which in each case contacts the sensor module); this can also be done, for example, simultaneously with at least one (signal) parameter of the first measurement signal, and / or in such a way that the second measurement signal follows the change of at least one measurement variable, wherein the proportional change of at least one signal parameter is within a predetermined measurement range. According to another embodiment of the invention, the sensor module is configured to set or change the first measurement signal and the second measurement signal such that the phase difference established between the said measurement signals, i.e. the difference between the (signal) phase of the first measurement signal and the (signal) phase of the second measurement signal, has a (proportional) dependence on the mass flow rate of the medium flowing through the sensor module, and / or such that at least one of the measurement signals has a (signal) frequency depending on the density of the medium contacting (or guided therein) the sensor module.

[0096] As Figure 1 Schematically shown in, the aforementioned at least one (measurement) tube 31 can be at least partly straight and / or at least partly curved, for example such that a central section of the tube wall extending between an end of a first section of the tube wall and a second section remote therefrom is designed in a U-shape or a V-shape. As already indicated, the at least one tube 31 is in particular also intended to be integrated into the path of the aforementioned (measurement substance) line. Additionally, the at least one (measurement) tube 31 is particularly configured to guide a fluid medium (such as the aforementioned measurement medium) in its inner cavity, in particular at least temporarily in a predeterminable flow direction, for example from the aforementioned first section end towards the aforementioned second section end, for example, i.e. entering or leaving via the aforementioned (measurement substance) line accordingly. According to another embodiment of the invention, the at least one (measurement) tube 31 is further configured to be vibrated, especially when the aforementioned medium is guided in the inner cavity of the tube or flows through the inner cavity.

[0097] The converter electronics of the measurement system according to the invention are also specifically configured to use at least one (first) measurement signal to determine a (digital) measurement value of at least one measurement variable, for example also using both the first measurement signal and the aforementioned second measurement signal, and at least one reference (measurement) value (pre)determined for at least one sensor module-specific calibration parameter (in particular (reference) frequency or (reference) phase or (reference) voltage) under reference (calibration) conditions, which characterizes the (correspondingly calibrated) sensor module or the measurement system (formed by combining with the base module); in particular, in such a way that the reference (measurement) value is used as a parameter value of the (converter) characteristic function implemented in the converter electronics, according to which (converter) characteristic function (in the measurement mode of the measurement system), based on at least one measurement signal or at least one (signal) parameter specified previously thereof, a measurement value of at least one measurement variable is determined or calculated, or the coefficients of the aforementioned (converter) characteristic function are instantiated. The reference (measurement) value of at least one (sensor module-specific) calibration parameter can be determined, for example, in the manufacturer's factory (before the sensor module is sent to the operator of the measurement system) and / or by means of a (different) (main) base module that is structurally the same as the base module and / or by means of a (reference) calibration medium that causes contact with the sensor module, for example, in a corresponding possibly also recognized calibration laboratory or in a corresponding possibly also recognized calibration factory, and / or corresponding to, for example, the (nominal) sensitivity of the measurement system specified or expected for the measurement variable or the (scale) zero point specified or expected by the measurement system. The reference (measurement) value of at least one calibration parameter can be stored, for example, in the aforementioned (information) storage element of the sensor module, in particular in a non-volatile or permanent manner. Alternatively or additionally, at least one reference (measurement) value can also be externally transmitted to the converter electronics, for example, via the aforementioned data line L2 from a superior electronic data processing system and / or from the aforementioned (field) control unit (for the measurement system) and / or by radio, before or during the (re)commissioning of the measurement system, for example, via data input, and stored there in a suitable manner, for example, in a non-volatile manner; this can also be advantageously done together with reference (measurement) data specifying the reference (calibration) conditions established when determining the reference (measurement) value. The reference (measurement) value can also be part of a set of reference values (stored in the above manner) that includes two or more reference (measurement) values for multiple sensor module-specific calibration parameters.

[0098] In addition, the transducer electronics can also be arranged to control or perform (after connection to the sensor module) the calibration of the basic modules of the measurement system in an automatic manner and / or in dialogue with the user of the measurement system and / or in combination with a superior electronic data processing system. In order to display (measurement system) data of the measurement system on-site and / or to operate or control the measurement system on-site during (re-)commissioning, it is also possible to use, for example, the aforementioned display and control element HMI for signal communication and / or the aforementioned external (on-site) control device coupled to the transducer electronics.

[0099] In order to store digital (measurement system) data such as at least one reference (measurement) value, the transducer electronics can also include at least one non-volatile memory (EEPROM). In addition to the reference (measurement) value, digital nominal or reference values that further characterize one or more (calibration) parameters of the sensor module, for example mechanically, electrically, and / or electromechanically, and / or reference (measurement) values of one or more calibration parameters of other sensor modules, which other sensor modules can subsequently be used for the basic module M1 and / or one or more electronic certificates of the (corresponding) measurement system and / or the (measurement system) data of the (corresponding) measurement system, such as one or more (digitized) measurement values and / or test results obtained therewith, can advantageously be stored in a non-volatile manner in the memory (EEPROM), and if necessary, also together with corresponding location and / or (system) time and / or date information. Thus, according to a further development, there is provided for reading into the transducer electronics, before or during (re-)commissioning of the measurement system, (measurement system) data containing at least one reference (measurement) value and / or (measurement system) data for identifying or validating the sensor module, which data, for example, is also stored in the aforementioned (information) storage element of the sensor module and / or in the aforementioned superior electronic data processing system EDP, for example, namely (immediately) before connecting the sensor module to the basic module and / or during connecting the sensor module to the basic module and / or (immediately) after connecting the sensor module to the basic module.

[0100] According to another embodiment of the invention, the basic module M2 has at least one first electric coil 12, which is electrically connected to the converter electronics, for example by means of corresponding (connecting) conductors. The coil 12 can be, for example, cylindrical and / or configured as an air coil and may also be at least partially coated with a plastic material. In particular, the coil 12 can also be used to generate or adjust - in this case inductive - a (first) measurement signal (in interaction with the sensor module M2). For example, the sensor module M2 can also be configured to induce an electrical (alternating) voltage (serving as the signal voltage of the measurement signal) of the (basic module) in the coil 12 and / or the (first) (alternating) voltage induced in the first electric coil 12 (using the sensor module) can be used as the (signal) voltage of the (inductive) measurement signal. Thus, according to another embodiment of the invention, the coil 12 is connected to the measurement signal input of the converter electronics. Additionally, the converter electronics are configured to detect the aforementioned electrical (alternating) voltage induced in the coil 12 (by means of the sensor module) and evaluate it as a (first) measurement signal, or use the aforementioned electrical (alternating) voltage induced in the coil 12 (by means of the sensor module) to determine the measured value of at least one measurement variable, for example, i.e., determine the (parameter) measured value of at least one parameter (such as amplitude, frequency, and / or phase angle) of the (alternating) voltage, and calculate the measured value of at least one measurement variable based on the (parameter) measured value determined for the (alternating) voltage. In the aforementioned case where the basic module M1 has a (protective) housing 11, the electric coil 12 can be arranged within the chamber 11* and is advantageously also held by the housing 11, for example, by the coil 12 being at least indirectly mechanically connected to the housing wall 11+.

[0101] According to another embodiment of the present invention, the sensor module M2 has at least one (e.g., cylindrical) first permanent magnet 22. In addition, the sensor module M2 can further include additional permanent magnets, each positioned at a certain distance from the permanent magnet 22, particularly cylindrical and / or structurally the same as the permanent magnet 22, such as at least one second permanent magnet 24. In the aforementioned case where the base module M1 also has at least one electrical coil 12 electrically connected to the converter electronics, the permanent magnet 22 is also connected to the sensor module M2 such that the permanent magnet 22 (when the sensor module M2 is connected to the base module M1 or when the measurement system is complete) remains in a static (first) mounting position predetermined with respect to the alignment with and / or the minimum distance from the electrical coil 12 and / or the imaginary longitudinal axis of the permanent magnet 22 and the imaginary longitudinal axis of the electrical coil 12 are aligned with each other or extend parallel to each other; this is particularly accomplished in such a way that the permanent magnet 22 and the electrical coil 12 form a voice coil in the said mounting position, particularly serving as an electrodynamic oscillation exciter, and / or especially in the aforementioned case, the electrical coil 12 is electrically connected to the measurement signal input - plunger coil of the converter electronics, particularly serving as an electrodynamic oscillation sensor. For the aforementioned case where the base module M1 has a (protective) housing 11, the sensor module M2 is also configured according to another embodiment of the present invention to be mounted in the base module M1 such that the aforementioned permanent magnet 22 is placed within the aforementioned chamber 11* but still spaced apart from the housing wall 11+, particularly remaining in the aforementioned static (first) mounting position E1, or (forming the aforementioned oscillation or plunger coil) positioned and aligned with respect to the coil 12 in the above - mentioned manner. Especially for the aforementioned case where the sensor module M2 has at least one second permanent magnet 24, the base module M1 in this embodiment of the present invention can also have at least one second electrical coil 14 placed within the chamber 11* of the (protective) housing, which is, for example, cylindrical and / or configured as an air coil and / or structurally the same as the first electrical coil 12, and the second electrical coil (removed from the electrical coil 12) is at least indirectly mechanically connected to the housing wall 11+ and is also electrically connected to the converter electronics. Additionally, the base module M2 can be additionally configured to receive the sensor module such that the permanent magnet 24 remains in a second mounting position, particularly with respect to alignment and / or away from the first mounting position, or such that the imaginary longitudinal axis of the permanent magnet 24 and the imaginary longitudinal axis of the electrical coil 14 are aligned with each other or extend parallel to each other. Furthermore, the sensor module M2 can also have more than two permanent magnets (22, 24) arranged at a certain distance from each other, thus having at least one third permanent magnet 26, and the base module M1 can have (within the chamber 11*) more than two electrical coils (14, 16) arranged at a certain distance from each other and / or each assigned to a permanent magnet, which are, for example, also the same in construction as the coil 12, thus having at least one third air coil 16.

[0102] For the foregoing case in which the sensor module has at least one (measurement) tube 31 or is formed by means of at least one (measurement) tube 31, as also schematically shown in Figure 1 , at least one permanent magnet 22 can be fixed to the outside of the tube wall of the tube 31, for example, i.e., outside the foregoing central section, in particular, by material-bonding connection thereto; if additionally present, the foregoing permanent magnet 24 and / or further permanent magnets (26) of the sensor module M2 can also be attached to the outside of the tube wall of the tube 31 or its central section. According to another embodiment of the invention, the basic module M1 and the sensor module M2 are also combined to form a vibration-type measurement sensor (of the measurement system), for example, such that the electromechanical oscillation exciter (12 + 22) is formed by means of the electric coil 12 (connected to the converter electronics ME) and the permanent magnet 22 (fixed to the outside of the tube) and / or the corresponding (electrodynamic) oscillation sensor of the measurement system is formed by means of the electric coils (12, 14, 16) (connected to the converter electronics ME) and one of the corresponding associated permanent magnets (22, 24 or 26) (fixed to the outside of the tube). Additionally, in this embodiment of the invention, at least one tube 31 or its central section is specifically configured (driven by an oscillation exciter powered by the converter electronics) to perform forced bending or resonant oscillation about a static rest position and / or to be caused to vibrate, such that at least one permanent magnet 22 moves relative to the electric coil 12, in particular, each of the other permanent magnets 24, 26 also moves relative to the corresponding electric coil 14 or 16; this is especially the case when the foregoing medium is guided through or flows through the inner cavity of the tube. Such mechanical oscillation of at least one (measurement) tube 31 or its central section can be excited or maintained, for example, by means of the foregoing oscillation exciter formed by the permanent magnet 22 and the coil 12, and / or detected by means of the foregoing oscillation sensor formed, for example, by the permanent magnet 22 and the coil 12 or by the permanent magnet 24 and the coil 14 or by the permanent magnet 26 and the coil 14, in particular, such that the corresponding oscillation sensors (22 + 12, 24 + 14, 26 + 16) provide at least one (first) measurement signal, in particular, both the first measurement signal and the foregoing second measurement signal (each in the form of an oscillation signal representing the oscillation of the tube 31 or its central section). In order to enable such vibration of at least one (measurement) tube 31 even when the sensor module is installed in the (protective) housing 11 of the basic module M1, according to another embodiment of the invention, the sensor module M2 is also installed in the (protective) housing 11 of the basic module M1, such that as also schematically shown in Figure 3a , at least one (measurement) tube 31 is at least partially, for example also completely, placed within the chamber 11*, but at least its foregoing central section is spaced apart from the housing wall 11+.

[0103] To stimulate and maintain the mechanical oscillation of at least one (measurement) tube 31 or of the sensor module M2 formed therewith, according to another embodiment, the converter electronics ME is also configured to at least temporarily provide a first electrical (measurement system) drive signal and introduce it into at least one electrical coil (12, 14 or 16) of the basic module M2, namely for example the first coil 12, in order to feed the electrical power required for the aforementioned mechanical oscillation (of the sensor module) into at least one electrical coil; in particular such that at least one (measurement system) drive signal has an applied alternating current and / or at least one signal frequency corresponding to the mechanical resonance frequency of the sensor module M2, in particular of at least one (measurement) tube 31 thereof. Alternatively or additionally, the converter electronics can, in particular in the aforementioned case where the basic module M1 includes at least a third electrical coil 16 in addition to the first and second electrical coils, also be configured to at least temporarily detect and evaluate, for example, a second electrical (alternating) voltage induced in the third coil 16 (of the basic module), for example in order to calculate a (parameter) measured value of at least one parameter of the second (alternating) voltage based on the second (alternating) voltage and / or to establish a phase difference between the aforementioned first (alternating) voltage and the second (alternating) voltage; in particular for the purpose of calculating a measured value of at least one measurement variable to be detected by the medium based on the phase difference. According to another embodiment of the invention, the converter electronics is also particularly configured to determine and evaluate the (parameter) measured value of the aforementioned phase difference, for example, namely to use one or more (parameter) measured values of the phase difference to determine a (mass flow rate) measured value and / or to compare them with previously determined (parameter) reference values and / or one or more thresholds predefined for this purpose within the framework of a (self-)diagnosis of the measurement system, and / or to determine a measured value of at least one measurement variable based on a phase difference established between the first and second (alternating) voltages (or one or more parameter measured values determined for this purpose) and at least one calibration parameter or a (converter) characteristic function formed therewith, in particular to determine the mass flow rate of the medium flowing through the sensor module according to a (phase difference to mass flow rate measurement value) characteristic function of the (converter electronics). It is quite common for such a sensor module or a vibration measurement system formed therewith that the sensor module M2 can also have at least one second (measurement) tube 32, which is for example also identical to the first tube in terms of construction and / or function, where the tube wall forms the outer shell surface of the second tube, in particular made of a metal or plastic material and having an inner cavity enclosed by the same tube wall. In this case, the aforementioned second permanent magnet 24 or another permanent magnet of the sensor module can be fixed to the second tube, in particular by a material-bonding connection to the second tube, which is for example also opposite to the permanent magnet 22 fixed to the first tube 31, and / or such that the imaginary longitudinal axis of the permanent magnet 24 and the imaginary longitudinal axis of the permanent magnet 22 are aligned with each other or extend parallel to each other.In particular, in the case where the sensor module M2 is formed by means of two tubes (31, 32), the sensor module M2 can also have more than three permanent magnets arranged at a certain distance from each other, for example, at least six permanent magnets in total, and the basic module M1 can correspondingly have more than three electric coils arranged at a certain distance from each other in the chamber 11*, for example, at least six electric coils in total. Each electric coil is, for example, configured as an air coil, for example, such that (in the case where the sensor module is mounted on the basic module) each of the two tubes is assigned exactly one oscillation exciter formed in the above manner and exactly two oscillation sensors formed in the above manner. The first (measurement) tube 31 and the second (measurement) tube 32 can also be fluidly connected to each other by means of a first diverter on the inlet side (fluidly connected to each of the two tubes) and a second diverter on the outlet side (fluidly connected to each of the two tubes), as is very common in vibration measurement systems of the type under discussion, and can also be integrated into the path of the aforementioned (measurement substance) pipeline during the operation of the measurement system.

[0104] Briefly stated, if a global re - check or verification of the functionality of the basic module M1 or the specified interaction of its (sub -) components is required, especially during the (re -) commissioning of the measurement system on - site, the basic module according to the invention is further calibrated using both a sensor module (which is already mechanically connected to the basic module and signal - communication - coupled to the converter electronics) and at least one reference (measurement) value specific to the sensor module (e.g., which is (simultaneously) stored in the converter electronics); this is especially done using both the converter electronics and a still - unused (brand - new) sensor module, i.e., a sensor module that has not been used for measuring at least one measured variable after being received from the manufacturer or after its (first) connection and coupling to the basic module, and / or using a sensor module connected to or coupled to the basic module immediately before its first use for measuring at least one measured variable, and / or enabling or detecting a reduction in the functionality of the basic module (e.g., impairing the measurement accuracy of the measurement system). Thus, according to another embodiment of the invention, the converter electronics is also configured to calibrate the basic module, for example, in an automatic or program - controlled manner, by means of a sensor module (which is mechanically connected to the basic module and signal - communication - coupled to the converter electronics) and at least one reference (measurement) value of a calibration parameter specific to the sensor module, e.g., by determining one or more (actual) measured values of at least one calibration parameter based on at least one measurement signal (set by the sensor module) and comparing them with at least one reference measurement value of (at least one calibration parameter). Especially when the above - mentioned measurement system is a mass - flow measurement (modular) vibration measurement system or a Coriolis mass flowmeter or when the (vibration) sensor module and the basic module are arranged to interact to generate the above - mentioned first measurement signal and second measurement signal with a phase difference depending on the mass flow, at least one calibration parameter can correspond to, for example, the (scale) zero point of the measurement system, which represents the (zero) phase difference to be measured (nominal) when the mass flow is zero, or the reference measurement value of (at least one calibration parameter) can correspondingly quantify the said (zero) phase difference.

[0105] The result of the calibration of the basic module according to the invention can be, for example, the verification or qualification of the basic module for further use in determining the measured value of at least one measured variable, or, for example, also for detecting damage or defects in the basic module, especially due to mechanical wear and / or (mechanical) deformation of one or more faulty (electronic) components or (electronic) assemblies of the basic module and / or the converter electronics.

[0106] According to another embodiment of the present invention, the calibration of the basic module (by means of the sensor module) also includes establishing (on-site) the calibration conditions of the (measurement system). The (on-site) calibration conditions can for example correspond to the aforementioned reference (calibration) conditions, that is, those (measurement) conditions established when determining the reference (measurement) values of specific calibration parameters of the sensor module (for example, during the (factory) calibration of the sensor module in the manufacturer's calibration laboratory or calibration facility). Alternatively or additionally, the (on-site) calibration conditions can be specified or defined correspondingly in the possible also electronic documentation of the sensor module. Therefore, establishing the (on-site) calibration conditions of the (measurement system) can include bringing the sensor module (connected to the basic module) into contact with an (on-site) calibration medium having for example a predetermined (medium) temperature and / or a predetermined (medium) pressure and / or a predetermined volume and / or mass flow rate. Therefore, the (on-site) calibration medium can for example have a constant (medium) temperature and / or a temperature corresponding to the (reference) temperature of the (reference calibration medium) prevailing under the reference (calibration) conditions, in particular a temperature not less than 20 °C, and / or a constant (medium) pressure and / or a static pressure corresponding to the (reference) pressure of the (reference calibration medium) corresponding to the reference (calibration) conditions, in particular a pressure not less than 0.8 bar, and / or a constant (medium) density and / or a density corresponding to the (reference) density of the (reference calibration medium) corresponding to the reference (calibration) conditions, for example 0.09 kg / m 3 or 1.29 kg / m 3 or 1000 kg / m 3 , and / or at least temporarily known and / or at least temporarily constant, in particular (constantly) zero mass flow rate, or characterized correspondingly. For example, a cleaning fluid is also suitable for (on-site) sterilization (SIP-sterilization in place) and / or water or (water) vapor, in particular having a (medium) temperature greater than 100 °C and / or a (medium) pressure not less than 1 bar, and / or air, in particular having a (medium) temperature not less than 20 °C and / or a (medium) pressure not less than 0.8 bar, and / or a (technical) purge gas, in particular air, carbon dioxide, nitrogen and / or argon, can be used as for example the calibration medium, in particular the reference calibration medium and / or the on-site calibration medium. Advantageously, the aforementioned line system for carrying the measurement medium can also be used to supply the calibration medium to the sensor module. Therefore, the integration of the sensor module into the line system is carried out (immediately) before the calibration of the basic module according to another embodiment or the calibration of the basic module is carried out only after the sensor module is also integrated into the pipeline system.

[0107] To ensure that the calibration starts in a targeted manner or to avoid the calibration starting in an uncontrolled manner, for example automatically by the transducer electronics, the calibration of the basic module according to another embodiment of the invention comprises executing a (calibration) command by the transducer electronics, in particular such that the measurement system is brought into a calibration operation or such that the use of the transducer electronics to determine one or more (actual) measurement values and their comparison with at least one reference (measurement) value (only thereby) is activated or made possible. The (calibration) command can be transmitted to the transducer electronics, for example, by signaling the establishment of (on-site) calibration conditions and / or by (manual) actuation of the aforementioned display and control elements (of the measurement system). Alternatively or additionally, the (calibration) command can also be issued to the transducer electronics from the outside, for example, by means of the aforementioned superior electronic data processing system (EDP) and / or by means of the aforementioned external (on-site) control device, for example via radio and / or infrared and / or wired by generating and / or sending a data transmission to the transducer electronics.

[0108] According to another embodiment of the invention, the calibration of the basic module further comprises generating at least one measurement signal (during the calibration operation of the measurement system or under (on-site) calibration conditions). In particular, in the case where the above-mentioned sensor module is a vibration sensor module or the measurement system formed therewith is a vibration measurement system, the generation of at least one measurement signal (under calibration conditions) can also comprise feeding electrical power into the sensor module, for example, into one or more of its aforementioned electrical coils and / or by generating a (first) electrical (measurement system) drive signal, or the generation of at least one measurement signal (under calibration conditions) can also comprise generating an electrical (measurement system) drive signal (for feeding electrical power into the sensor module) by means of the transducer electronics, for example, using an externally applied alternating current and / or using a signal frequency corresponding to the mechanical resonance frequency of the sensor module.

[0109] According to another embodiment of the invention, the calibration of the basic module further comprises using converter electronics to determine one or more (actual) measured values of at least one calibration parameter based on a measurement signal (generated under calibration conditions), or the converter electronics are correspondingly arranged to perform or control the calibration of the basic module (interacting with the sensor module connected thereto). Additionally, according to another embodiment of the invention, the calibration of the basic module comprises comparing one or more (actual) measured values with at least one reference (measurement) value of (at least one calibration parameter). The comparison of one or more (actual) measured values with at least one reference (measurement) value can advantageously be carried out directly within the converter electronics and / or can include determining (statistical) core metrics of the (actual) measured values, such as position measurement of the (actual) measured values and / or discrete measurement of the (actual) measured values, and / or determining the deviation of one or more (actual) measured values or the aforementioned position measurement of the (actual) measured values from at least one reference (measurement) value. Furthermore, the comparison of one or more (actual) measured values with at least one reference (measurement) value can also include comparing the aforementioned deviation of one or more (actual) measured values from at least one reference (measurement) value with a predetermined (deviation) threshold, which for example indicates a defective basic module and / or serves as a tolerance measurement for a (still) intact basic module or measurement system and / or as a limit of the tolerance range specified for a (still) intact basic module or measurement system, and / or comparing the (statistical) core metric with a predetermined (core metric) threshold, which for example indicates a defective basic module and / or serves as a tolerance measurement for a (still) intact basic module or measurement system and / or as a limit of the tolerance range specified for a (still) intact basic module or measurement system. Exceeding the corresponding at least one predetermined threshold can also be used to initiate or trigger the generation of a (fault) message and / or block the basic module. Alternatively or additionally, the comparison of one or more (actual) measured values with at least one reference (measurement) value can also include storing the corresponding (comparison) result ("pass / fail") in the converter electronics and / or in the aforementioned data processing system (EDP), for example also together with the (measured) data specifying the (field) calibration conditions and / or together with information specifying the location and / or (system) time and / or date of the calibration. Each of the aforementioned thresholds can also be used, for example, in the non-volatile memory (EEPROM) of the converter electronics. Thus, the calibration of the basic module can further include detecting damage or defects ("failure" - negative test or comparison result) in the basic module, particularly accompanied by a corresponding (field) message and / or at least temporary blocking of the basic module, for further use in determining (qualified) measured values of at least one measurement variable. The (to be detected or detected) damage or (to be detected or detected) defect can also be, for example, a reduction in the functionality of the basic module, which impairs the accuracy of the measurement system.

[0110] According to another embodiment of the present invention, the calibration of the basic module (in the case of a negative check result) further includes generating a (fault) message ("failure"), which signals a damaged or at least partially defective basic module, in particular a (fault) message that can also be visually perceived on-site, and / or also (at least temporarily) preventing the basic module from being used (further) for the measurement operation of the (measurement system); this also applies in each case particularly to the foregoing situations: one or more (actual) measurement values deviate from at least one reference (measurement) value by more than a predetermined tolerance level, and / or the deviation of one or more (actual) measurement values from at least one reference (measurement) value and / or the foregoing (statistical) core indicators are outside the (corresponding) tolerance ranges specified for a complete basic module or measurement system. In order to output the (fault) message, for example, also for its transmission to a higher-level data processing system (EDP) or for on-site display, for example, the foregoing data output of the converter electronics or the foregoing display and control elements of the measurement system can also be used.

[0111] The foregoing (at least temporary) prevention of the basic module can also include removing the sensor module from the (at least temporarily prevented) basic module and / or connecting the sensor module to another (unprevented) basic module, for example, an adjacent and / or identical (second) basic module to the (at least temporarily prevented) basic module (on-site); this can be done, for example, to check the sensor module itself (immediately after preventing the basic module) and / or to verify the reasonableness of the foregoing negative (comparison) result ("failure") or to reconfirm it (immediately after preventing the basic module). Alternatively or additionally, the calibration of the basic module can also include using an additional (second) sensor module and / or test module, for example, according to the above-mentioned international application PCT / EP2022 / 076349, for repeatedly checking the basic module; this also applies particularly to the foregoing situations where there is an (initial) negative check result, or where one or more (actual) measurement values deviate from at least one reference (measurement) value by more than a predetermined tolerance level and / or where the deviation of one or more (actual) measurement values from at least one reference (measurement) value and / or the (statistical) core indicators of the (actual) measurement values are outside the (corresponding) tolerance ranges specified for a complete basic module or measurement system. The repeated checking of the basic module by means of another (second) sensor module (in particular the same sensor module as the sensor module) and / or the foregoing test module can also be performed, for example, (immediately) after the foregoing (fault) message has been generated or after the foregoing prevention of the basic module has been performed. Additionally, for example, preventing the basic module or creating a (fault) message also initiates replacing the defective basic module with a complete (new) basic module; this can also be accompanied by a new (on-site) calibration of the (new) basic module, for example, a new (on-site) calibration using the foregoing test module and / or another sensor module.

[0112] As an alternative to the foregoing output of the blocking or fault message as the basic module, the calibration of the basic module may also include releasing the basic module for (further) measurement operations of the (measurement system) or for determining the measured values of at least one measurement variable in the (measurement operation); this applies at least in the case where there is a positive check or comparison result ("pass") or where one or more (actual) measured values do not deviate from at least one reference (measurement) value or deviate by less than a predetermined tolerance level, for example also only where none of the one or more (actual) measured values deviates from at least one reference (measurement) value by more than the tolerance level, and / or where the foregoing deviation of one or more (actual) measured values from at least one reference (measurement) value and / or the foregoing (statistical) core indicators of the (actual) measured values are within the (corresponding) tolerance ranges specified for the complete basic module or measurement system. The release of the basic module can in particular also include or implement determining the measured values of at least one measurement variable using at least one reference (measurement) value of a measurement system formed by means of the basic module and the sensor module and / or of at least one calibration parameter in the (measurement operation of the measurement system). In order to (further) on-site check the sensor module, it can be occasionally temporarily connected to another basic module, such as the foregoing (adjacent) second basic module. In particular in the foregoing case where the sensor module is only approved for single-use and / or time-limited use (e.g., due to the type of measurement medium and / or process), after the sensor module has been removed from the basic module (and a new sensor module has been replaced), the sensor module can advantageously be sent back to the manufacturer, for example to be re-measured (for the traceability of the measured values collected by means of the sensor module) and / or updated (for reuse).

[0113] To ensure that the sensor module is actually a legitimate sensor module for forming a measurement system or for use in a base module, for example also for its calibration, it can also be advantageous to (field) check the sensor module, in particular to verify the sensor module or confirm its legitimacy for use in the base module; this can be done especially before connecting to the base module or before calibrating the base module and / or by comparing data identifying the sensor module with corresponding default data. According to another embodiment of the invention, the checking of the sensor module accordingly includes, for example, using the converter electronics and / or the aforementioned (information) storage element of the sensor module to (field) verify or authenticate the sensor module, and if necessary, also includes the aforementioned higher-level electronic data processing system EDP connected to the converter electronics. For example, the checking of the sensor module can also include checking whether the sensor module is suitable or (still) approved for forming a measurement system and / or calibrating the base module, for example also based on one or more (electronic) certificates and / or (electronic) seals of the sensor module, which may also be attached to the outer packaging of the sensor module used for transport protection. The electronic data required for checking the sensor module can be stored, for example (partially), in the converter electronics and / or in the aforementioned (information) storage element of the sensor module and / or in the aforementioned higher-level electronic data processing system EDP, and can be retrieved appropriately from there. The checking of the sensor module can be performed, for example, in an automated manner and / or by (manual) actuation of the aforementioned display and control element HMI and / or by means of the aforementioned external (field) control device for starting or controlling. The aforementioned (field) control unit can also be arranged or specifically used to check the aforementioned (electronic) seal of the sensor module. Thus, the checking of the sensor module can also include releasing the sensor module for forming a measurement system and calibrating the base module if the sensor module is approved for this purpose, for example using the converter electronics or enabling the measurement system to implement or activate a calibration operation for calibration by means of the converter electronics. Alternatively, if the sensor module is not approved for use in the base module or has not been properly verified, the checking of the sensor module can also result in the sensor module being blocked; for example, this can occur during or (immediately) after checking the sensor module and / or in such a way that the sensor module is also blocked for further calibration of the base module and / or for calibration of another base module, for example by invalidating the aforementioned certificate of the sensor module.
