Description

TECHNICAL FIELD

[0001] The invention relates to a field device structure according to the features of independent claim 1.

[0002] Field devices with cast housings, which have at least one chamber, are known from the prior art. Fig. 1a-c shows an opened Rosemount field device housing from 2010. Two pin contacts encapsulated with a potting compound establish electrical contact between two separate chambers of the housing.

[0003] Furthermore, DE102021132304A1 discloses a field device with two chambers separated from each other by a partition. The partition has a drilled through-hole whose walls have a partially structured surface. A thread, for example, is proposed for the structured surface. A conductor element is at least partially inserted into the through-hole for the electronic connection of two units. The through-hole is further sealed with a potting compound.

[0004] The disadvantages of the state of the art are the sometimes high post-processing effort required for the housing or chamber feedthroughs and the limited number of electrical connections. OBJECT OF THE INVENTION

[0005] The disadvantages of the state of the art give rise to the task of providing an improved concept of a chamber feedthrough that meets the requirements for use in potentially explosive atmospheres.

[0006] The object is achieved according to the invention by the features of independent claim 1.

[0007] Possible embodiments and further developments of the invention are the subject of the dependent claims. SUMMARY OF THE INVENTION

[0008] A field device assembly for process and automation technology comprises a housing, at least one first chamber and a second chamber arranged in the housing, wherein at least one first module is arranged in the first chamber and at least one second module is arranged in the second chamber, wherein the two chambers are connected via at least one passage. Furthermore, the field device assembly comprises an electrical connection element which is guided in at least one passage, wherein the electrical connection element is provided to establish an electrical connection between the first module and the second module. The electrical connection element consists at least partially of rigid and flexible sections and is provided with contact surfaces or contact elements for contacting the modules.

[0009] The electrical connection element can be, for example, a rigid-flex circuit board. The contact elements can be, for example, pins, plugs, sockets, or the like. Using a rigid-flex circuit board allows for versatile use of the electrical connection element and also simplifies its assembly.

[0010] At least one of the modules can be a terminal block for connecting electrical cables, such as a 4-20mA loop or a bus system. Furthermore, one of the modules can also be an evaluation unit for evaluating and processing measured values ​​and data. Both modules can be installed in either chamber and interchangeable. This makes the housing particularly versatile and flexible in its application.

[0011] In one possible embodiment of the field device design, the housing has a third chamber in which a sensor module is arranged. The sensor module can, for example, comprise a pressure, temperature, or level sensor. Such a multi-chamber housing has the advantage that several units / modules or sensors can be arranged separately in different chambers. The chambers themselves thus remain as small as possible, and the oxygen-containing air contained therein, which can ignite under unfavorable conditions, can be reduced to a minimum.

[0012] In one possible embodiment of the field device structure, the housing is provided with at least two passages, with a first passage connecting the first chamber with the second chamber and a second passage connecting the first chamber with the third chamber. Furthermore, it is also conceivable for the second chamber to be connected to the third chamber via a passage. The design with two passages is particularly advantageous for the requirements of ignition protection type Ex-d, since, in contrast to a single passage, large free spaces are avoided. This advantage is further enhanced if the cross-section of the passages is selected to be as small as possible.

[0013] In one possible embodiment of the field device assembly, the electrical connection element establishes an electrical connection both between the first module and the second module, and between the first module and the sensor module. The electrical connection element is designed, for example, to be multi-pole for simultaneous and independent power supply, data, and / or signal transmission. The electrical connection element is guided in the at least one passageway in such a way that the inner walls of the passageway are not touched. Auxiliary elements, such as small plastic spacers, hairs, a plastic spring, or a plastic coil, can also be provided for this purpose.

[0014] In one possible embodiment of the field device design, the first chamber and the second chamber are arranged at an angle to each other. The angle of the chambers to each other can, for example, be in a range of 5 to 90 degrees, in particular between 15 and 30 degrees. Likewise, the housing around the respective chambers can have the aforementioned angle range. The angled arrangement of the chambers can also result in an angled passage. An angled housing improves the readability of displays or status lights in the chambers.

[0015] In one possible embodiment of the field device design, at least one passage is sealed with a potting material. The potting material can be, for example, epoxy resin or similar. The potting seals the passage(s). Furthermore, the requirements for Ex-d and Ex-i types of protection can be met.

[0016] In one possible embodiment of the field device structure, the rigid sections of the electrical connection element are arranged in a receptacle in an entrance area of ​​the passage, thereby at least partially covering the passage. At least one rigid section is arranged in the entrance area, for example, in such a way that it is flush with an inner wall of the respective chamber.

[0017] In one possible embodiment of the field device design, a sealing element is arranged in the entrance area of ​​the passage. The sealing element, together with the shape of the entrance area and the rigid section of the electrical connection element, achieves an additionally enhanced sealing effect.

[0018] In one possible embodiment of the field device structure, at least one rigid section of the electrical connection element is pressed into an input area of ​​the passage or a sealing element mounted there, sealing the passage, wherein the opposite opening of the passage is at least partially covered by a further rigid section of the electrical connection element. The potting compound can be poured into the passage particularly easily from the only partially covered opening of the passage. The completely sealed opening opposite prevents uncontrolled flow or leakage of the potting compound. In a further embodiment, a plug or socket is arranged on the rigid section which only partially covers the opening of the passage, so that the potting compound can also be potted over the rigid section. The plug or socket remains.The socket is still contactable. Contact surfaces arranged on the rigid section can thus be easily insulated.

[0019] In one possible embodiment of the field device structure, the at least one passage has at least one undercut. This can effectively extend a creepage distance. A further advantageous embodiment can be that at least two undercuts are arranged symmetrically in each passage, maintaining the same distance from the respective rigid sections mounted at the openings of the passage. This design is particularly advantageous in the case of large temperature fluctuations, since the undercuts can prevent the encapsulation in the passage from detaching.

[0020] The use of cast parts and housing parts without post-processing is particularly advantageous, since the interaction of undercut with the cast part surface and surface roughness results in an optimal combination of sealing effect and adhesion with regard to compressive strength and tightness.

[0021] In one possible embodiment of the field device structure, the rigid sections of the electrical connection element consist of multiple layers and have contact surfaces and / or connectors on at least one surface facing the modules, which establish the electrical connection to the modules. The arrangement of connectors makes it possible, for example, to encapsulate the rigid section with the potting compound and thus insulate it, while still maintaining electrical contactability. A multilayer printed circuit board allows a large number of electrical cables to be routed separately from one another in a small space.

[0022] In one possible embodiment of the field device structure, the rigid sections of the electrical connection element comprise electrical and / or electronic components. The components can be, for example, resistors, capacitors, transistors, or microcontrollers, some of which can be arranged on an uppermost layer of the electrical connection element or on internal layers. By integrating electrical and / or electronic components into the electrical connection element, the available free space in the passage is utilized.

[0023] In one possible embodiment of the field device design, the flexible sections of the electrical connection element are arranged in the at least one passage. This allows for particularly simple assembly in an angled housing with angled chambers. It can be particularly advantageous in this context for the flexible section to be longer than the length of the passage. This also allows for particularly simple assembly.

[0024] In one possible embodiment of the field device assembly, the first module and / or the second module are designed such that a display module can be plugged onto it. One of the two modules can be designed such that a display module can be plugged on and locked in a simple manner, for example, using a bayonet lock. Furthermore, both modules can have an identical connection or terminal block so that the display module can be arranged in both chambers. With an angled housing, this results in different angles at which a display on the display module can be read.

[0025] In one possible embodiment of the field device structure, the housing is manufactured from sheet metal using a casting, die casting, or hydroforming process, with the inner walls of the passageway also being unmachined. A housing manufactured using the hydroforming process is particularly suitable for use in the food and beverage industry. In contrast, a housing made of cast iron, for example gray cast iron, is particularly robust and can withstand high pressures. The inner surfaces of the passageway of a cast housing do not need to be remachined for potting with a potting compound, as a cast housing already has a certain roughness to which the potting material can adhere and is routinely subjected to various cleaning processes after production to remove, for example, release agents or slight burrs. In addition to rinsing processes, these processes also include vibratory grinding or sandblasting.

[0026] In one possible embodiment of the field device design, the electrical connection element is encapsulated in a block that is centrally located within the housing. This design is particularly advantageous in conjunction with housings manufactured using the hydroforming process. This allows for particularly good and simple sealing of the chambers. The block can also be prefabricated outside the housing, for example, and then attached to the housing as an assembly, for example, by gluing.

[0027] In one possible configuration of the field device assembly, the modules are fixed and / or oriented to the block. The modules can be screwed to the block, for example, or plugged into the block. Furthermore, a display module can be mounted in the chambers. An angled housing and a correspondingly angled block allow the display module to be aligned in the chamber in such a way that the display module's display is clearly legible. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiments of the invention are explained in more detail below with reference to drawings.

[0029] Showing: Fig. 1a-c show a state of the art, namely a field device housing with a potted chamber feedthrough from Rosemount, Fig. 2 a first embodiment of a field device structure, Fig. 3 schematically shows an electrical connection element, Fig. 4 a second embodiment of a field device structure, Fig. 5 a third embodiment of a field device structure, Fig. 6 shows a further embodiment of an electrical connecting element, and Fig. 7 another embodiment of a field device structure with cloud connection.

[0030] Corresponding parts are provided with the same reference numerals in all figures.

[0031] In the Fig. 1a-c shows a field device housing from Rosemount. Fig. Figure 1a shows an open housing 100 with a cover 101 and a terminal block 102 to the left. The terminal block 102 has two sockets on the rear (hidden in the figure) that are provided for receiving the pin contacts 106. A chamber 103 of the housing 100 has a chamber feedthrough 105 with two pin contacts 106. The chamber feedthrough 105 with the pin contacts 106 is completely surrounded by a potting compound 107.

[0032] Figure 1b shows a top view of the chamber 103 of the opened housing 100. In contrast, the Fig. 1c shows an oblique view to more clearly illustrate the dimensions of the chamber 103. Here, the chamber feedthrough 105 with the complete encapsulation 107, from which the pin contacts 106 protrude, is particularly clearly visible.

[0033] The Fig. Figure 2 shows a possible embodiment of a field device assembly (1). A housing (14) has at least two chambers (2, 3), with a first module (4a) arranged in the first chamber (2) and a second module (4b) arranged in the second chamber (3). The chambers (2, 3) are each closed by a cover (22, 23).

[0034] At a lower end of the field device assembly (1) there is a third chamber which contains a sensor module (8) and is closed by a process connection (7).

[0035] The housing (14) has two passages (12, 13) between the first chamber (4a) and the second chamber (4b) and between the first chamber (4a) and the third chamber. To establish an electrical connection between the chambers, an electrical connecting means (6) is guided in the passages (12, 13). The electrical connecting means (6) comprises rigid and flexible sections, with the flexible sections being guided in the passages (12, 13). The rigid sections are located at the inlets and outlets of the passages (12, 13), respectively. The shape of the inlets and outlets of the respective passage (12, 13) corresponds to the shape of the rigid section of the electrical connecting means (6). This achieves a high sealing effect even without additional sealing means.

[0036] The Fig. Figure 3 shows a possible embodiment of the electrical connection element (6). The electrical connection element (6) is, for example, a rigid printed circuit board which has flexible sections (6f,g,h,j,k) on at least one side. The flexible sections (6g,h) are formed between two rigid sections (6a,b,c). The open ends of the flexible sections (6f,j,k) are provided with contact surfaces (6x,y,z) or plugs. The rigid sections can have electrical and / or electronic components (16), as shown, for example, on the rigid section (6c). At least one of the rigid sections (6a,b,c) can also be mounted in a sealing element (20).

[0037] The Fig. Figure 4 shows another embodiment of a field device assembly (1). For clarity, the housing (14) is shown rotated 180 degrees to illustrate a possible potting process. The housing (14) has a central passage (12) with several branching branches. Each branch leads into a chamber (4a, 4b, 11, 19). The chambers (4a, 4b, 11, 19) are completely covered by rigid sections of the electrical connector. Additional sealing is achieved by the sealing elements (20a, b, c).

[0038] During the potting process, a funnel (24) is placed at the opening of the passage (12) in the third chamber (11), and potting compound (17) is poured in. The rigid section of the connecting means (6) in the chamber (11) does not completely close off the opening of the passage (12), which makes it easier to fill with the potting compound (17). The potting compound (17) flows under gravity into the chamber (19), in which a radio antenna (18) is arranged. The radio antenna (19) can be electrically contacted with modules in the chambers (4a, 4b, 11) via the electrical connecting element (6). The potting compound (17) reaches each branch of the passage (12) until the passage (12) is completely filled.

[0039] The Fig. Figure 5 shows another embodiment of the field device assembly (1). The housing (14) is manufactured using the hydroforming process. Seals (21) are arranged between the individual housing elements. The sealing lips of the seals (21) are flush with the outer walls of the housing elements, making this embodiment particularly suitable for the food and beverage industry.

[0040] A block (50) can be inserted over one of the chambers (2, 3, 11), which subdivides the housing (14) into the chambers as such. The block (50) comprises the electrical connection element (6), via which an electrical connection can be established between modules (4a, 4b) and the sensor (8) in the chambers (2, 3, 11). The block (50) is mounted and / or fixed in a bearing (51) which is arranged on the chamber (11). The bearing (51) can additionally fulfill the function of a seal and seal the chamber (11) with the sensor (8).

[0041] The Fig. Figure 6 schematically shows two embodiments of the electrical connecting element (6). Contact surfaces (6z) are brought into contact with corresponding contact tongues in a terminal (10). The contact surfaces are coated with tin, silver, or gold and have at least one contact point, but preferably contact is made on each side, so that two contact pairs interact, receiving the mating contact between them. An alternative is the use of a so-called piercing terminal (6p). Here, finished contact systems, the individual contacts, are crimped through the flexible conductor tracks, i.e. they penetrate and contact the flexible conductor tracks.

[0042] In Fig.7 shows a further embodiment of a field device structure (1), in which the field devices (1A, 1B, 1C, 1C) are connected on the one hand to a controller (89) or a PLC, process control system (81), and on the other hand to an AI / KI system which works with methods of artificial intelligence.

[0043] Here, at least one field device assembly (1B) is located in a safe industrial zone (93), whereas other components can be installed in a normal industrial zone (94).

[0044] The at least one field device structure (1B) communicates on the one hand via a secure connection such as 4-20 mA or APL with a controller (89) and a higher-level process control system, PLC (81), which can be viewed or controlled by a user (88) via a terminal (78).

[0045] Such a communication path [A] (91) is preferably wired.

[0046] The at least one field device structure communicates, on the other hand, via a further connection, wired via a switch (80) or wirelessly via a radio antenna (18) with a radio connection point (83) and transmits data from its sensor modules (30) which evaluate pressure or temperature sensors (70), or level switches (71) or level sensors (72) or other sensors, such as humidity, vibration, light incidence or internal pressure, ... which can also be integrated into the housing (14) and are connected to an internal module (4) via the electrical connecting element (6).

[0047] This second connection [B] (90) is preferably wireless, but can also be wired. The data reaches a cloud (82) via this second path, from which the data is centralized and clearly presented to the user (88) in cockpit views, additionally via the second connection (62).

[0048] However, via this second route, the data is still sent to a server (60), where it is preferably temporarily stored and then analyzed and evaluated by an AI system. Methods such as pattern recognition and deep learning are used here.

[0049] In a first step, the data is analyzed and stored in the AI ​​system. In a second step, the incoming data is compared with previous data and the resulting insights by the AI ​​software. The analysis results of the AI ​​system are then stored on the server (60), made available, and made available to the user at a terminal (78) via a third connection (63), supplemented with recommended actions and warnings.

[0050] The user can prefer analyses from this additional data and provide input and feedback via this third path (63) to the AI ​​ / KI system as to which data analyses should be intensified with priority.

[0051] Results and information from the AI ​​ / KI system can also be returned to the field device structure (64) if this is previously provided for in a profile for the device and released by the user (88).

[0052] Such results and information of the AI ​​ / KI system can also be requested, viewed and used manually by the user on-site via a module (4A).

[0053] In this case, the module or field device structure has an inner “safe area”, which is particularly set up for the prioritized transmission of data via the first connection, and an “evaluation / display area”, which displays or evaluates information played back via a second firmware and / or hardware structure or outputs it in the form of service or alarm signals.

[0054] Such signals can concern rising internal pressure or humidity, unauthorized opening, or leakage of the relevant housing (14), as well as analyzed irregularities, fluctuations, or reaching of limit values ​​of a measured value such as pulsation, cavitation, corrosion, or vibration. In particular, information is also displayed graphically as a value or graphic, or in relation to a time curve, while data continues to be transmitted in parallel in the background via the first connection.

[0055] For the separation between communication concerning the “safe area” and the “evaluation / display area” or the first and second, third connection path, the internal electrical connection set (6) for these areas is equipped with separate conductor connections for the different connection paths.

[0056] A “safe industrial zone” or a “safe area” is in particular an application or an area with requirements according to SIL or Ex-i or Ex-d explosion protection requirements.

[0057] The invention is not limited to the foregoing detailed embodiments. It may be modified within the scope of the following claims. Likewise, individual aspects of the subclaims may be combined with one another.
