Description

Field of invention

[0001] The invention relates to an adapter arrangement for mounting a readout adapter on a field device for reading measured values ​​from the field device, a mechanical adapter, a measuring system and the use of an adapter arrangement for detachably mounting a readout adapter on a field device for reading measured values ​​from the field device. background

[0002] In industrial process automation, field devices are used to acquire measured values ​​and transmit them to higher-level automation or control systems. Beyond their regular integration into such a system, many applications require the ability to read or access additional information from a field device without affecting ongoing operation. Such additional access may be necessary, for example, for service and diagnostic purposes, checking the device status, time-limited data acquisition, connecting to separate monitoring or evaluation systems, or for maintenance and repair tasks. In these cases, it is often desirable or even necessary for existing electrical connections and system integrations to remain unchanged to avoid interruptions or disruptions to process operation.

[0003] Various technical approaches exist for implementing additional data retrieval capabilities, such as contactless or optical communication methods, or separate service and auxiliary interfaces. However, their use requires the appropriate mounting of an external readout device on the field device. Known solutions for this are often only of limited practicality, as they lack sufficient mechanical stability or positioning accuracy, require the use of tools, or are only suitable for specific device configurations. Against this background, there is a need for an improved solution that enables the simple, reliable, and flexible mounting of an external readout device on a field device without disrupting existing plant operations. Summary

[0004] The object of the invention is to provide an adapter arrangement that enables simple, reliable and flexible mounting of an external readout adapter to a field device without interfering with the electronics, circuitry or wiring of the field device.

[0005] This problem is solved by the subject matter of the independent claims. Further developments of the invention are described in the dependent claims and in the following description.

[0006] One aspect of the invention relates to an adapter arrangement for mounting a readout adapter on a field device for reading measured values ​​from the field device. The adapter arrangement comprises a mechanical adapter with a base body and at least one mounting unit. The base body has a front and a rear opposite the front, which, in a mounted state, faces the field device. The mechanical adapter is essentially designed as a cap with a substantially cylindrical recess on the rear and has a rim. The mounting unit is designed to attach the mechanical adapter and / or the readout adapter to the field device without altering the electrical wiring of the field device.

[0007] This design allows the adapter arrangement, or the mechanical or geometric adapter, to serve as a purely mechanical interface between the field device and the readout adapter. This enables the reading of additional measured values, diagnostic information, or status data from the field device, while the field device remains unchanged and integrated into an existing automation or control system. In particular, the adapter arrangement can facilitate the acquisition of information that is not transmitted, or not permanently transmitted, to a DCS or SCADA system, such as secondary measured values, internal variables, or diagnostic states.

[0008] The outer contour of the mechanical adapter can be of any shape. It should be noted that the recess on the back can fit snugly onto the housing of the field device. Alternatively or additionally, a clamp or clip can be provided, which can be cut off at the top and bottom and attached to the field device at multiple points or on the sides.

[0009] For example, the mechanical adapter can be designed in a disc shape, at least in sections, and have an edge area in which the fastening unit can be arranged.

[0010] In the context of the present invention, a disc-shaped configuration is understood to be a substantially flat, preferably cylindrical structure whose extent in a principal plane is significantly greater than its extent perpendicular to that principal plane. Such a disc-shaped configuration can be completely or partially circular. The term "at least partially disc-shaped" also includes configurations in which the disc-shaped structure is partially trimmed, recessed, or interrupted, as long as a substantial portion of a substantially round outer contour is retained. This can be the case, for example, if the base body has recesses, flattened areas, or openings that, however, do not negate the fundamental disc-like geometry.In particular, it is sufficient that a relevant part of the outer contour has a circular or circular segment shape, so that the basic body can still be considered disc-shaped within the meaning of the invention.

[0011] The adapter arrangement can be designed so that the readout adapter can be positioned with precise accuracy relative to a readout or communication interface of the field device. This can be particularly advantageous for contactless or optical readout principles, such as infrared or NFC-based interfaces. The geometric design of the mechanical adapter can support reliable alignment of the readout adapter, thus enabling stable and reproducible communication even over extended periods.

[0012] Another technical advantage is that the adapter arrangement is suitable for temporary or permanent use. The readout adapter can be securely attached to the field device, for example, for service, diagnostic, or monitoring tasks, without having to open the field device housing or expose internal components. At the same time, the adapter arrangement can be designed to be detached without tools and even by untrained personnel, thus simplifying service and maintenance processes.

[0013] Furthermore, the adapter arrangement can be designed to maintain the visibility of a display unit or signal lights on the field device and / or the readout adapter. Additionally, the adapter arrangement can support different mounting principles, allowing it to be used on field devices with various housing types and interfaces. This ensures high flexibility and compatibility with existing device platforms.

[0014] The adapter arrangement can be advantageously suited for applications such as temporary data recording, device verification, troubleshooting, firmware updates, or connection to a separate monitoring or IoT system as an additional monitoring layer. In all these applications, the solution according to the invention ensures that the ongoing process operation is not disrupted and that no interventions in the electrical or system-related integration of the field device are required.

[0015] According to one embodiment, the adapter arrangement can additionally include a readout adapter that serves as a communication interface between the field device and an external readout device. The readout adapter can be configured to receive measured values, diagnostic information, or status data from the field device and forward them to the external readout device.

[0016] The readout adapter can be designed as a standalone module that communicates with the field device wirelessly or without physical contact. This communication can be optical, electromagnetic, or wireless, for example, without requiring a direct electrical connection to the field device. In this way, the readout adapter can act as an intermediary interface, allowing an external readout device to access information from the field device while the field device remains integrated into an existing automation or control system.

[0017] By designing the readout adapter as a communication interface, it becomes possible to connect various external readout devices, such as mobile devices, service tools, or evaluation units. At the same time, the separation between the mechanical adapter assembly and the communication function allows for flexible adaptation to different communication standards or future expansions.

[0018] According to another embodiment, the mechanical adapter and the readout adapter can be designed to be mounted together. In this case, the readout adapter can, for example, be held in a receiving area of ​​the mechanical adapter, so that both components can be attached to the field device together as a single unit. This simplifies the mounting process and achieves a defined spatial relationship between the readout adapter and the field device.

[0019] Alternatively or additionally, the mechanical adapter and the readout adapter can also be integrally designed. In such an embodiment, the readout adapter can be fully or partially integrated into the mechanical adapter, resulting in a compact design. This can be particularly advantageous if the readout adapter is to remain permanently attached to the field device or if a particularly robust and space-saving solution is desired.

[0020] The option of a modular or integrated design allows the adapter arrangement to be flexibly adapted to different applications, such as temporary service deployments or longer-term monitoring and diagnostic applications. At the same time, reliable alignment and positioning of the readout adapter relative to the field device can be ensured.

[0021] According to another embodiment, the base body of the mechanical adapter can have a first opening through which a display unit of the field device remains visible in the mounted state.

[0022] The opening can be positioned and sized so that essential display content, such as measured values, status information, or operating instructions, remains legible even with the adapter assembly installed. The design of the first opening ensures that the readout adapter and the adapter assembly do not impair the normal operation and usability of the field device. In particular, it allows operating or service personnel to use information from the field device's display unit in parallel with additional readout or diagnostic functions.

[0023] The opening can be adapted to different display sizes and positions, making the adapter assembly suitable for various field device types. This ensures high user-friendliness without compromising the mechanical stability or functionality of the adapter assembly.

[0024] According to another embodiment, the first opening can be symmetrical or asymmetrical.

[0025] A symmetrical design allows for flexible mounting of the adapter assembly in different orientations. Conversely, an asymmetrical design can be used to position the adapter assembly in a predetermined orientation on the field device or to adapt it to specific geometric features of the display unit. This ensures consistent visibility of the display unit even with different device variants.

[0026] According to another embodiment, the adapter arrangement can have a receiving area that is intended for receiving the readout adapter.

[0027] The mounting area can be designed to mechanically hold and position the readout adapter without requiring additional fasteners. This allows for a compact and organized component layout. Furthermore, the mounting area can help protect the readout adapter from external influences and ensure a defined position of the readout adapter relative to the mechanical adapter. This supports reliable operation of the readout interface.

[0028] According to another embodiment, the receiving area can be arranged on the back of the base body, so that the readout adapter can be mounted between the mechanical adapter and the field device.

[0029] This arrangement allows the readout adapter to be positioned particularly close to a readout or communication interface of the field device. Furthermore, placing the readout adapter between the mechanical adapter and the field device can help to mechanically protect the readout adapter while simultaneously enabling a space-saving design. This makes the adapter arrangement particularly suitable for use in confined installation situations.

[0030] According to a further embodiment, the base body of the mechanical adapter can have a substantially circular surface on its front side. Such a surface shape can serve to align the readout adapter relative to a display unit and / or a front panel of the field device.

[0031] The circular geometry enables uniform and reproducible positioning of the readout adapter. Furthermore, the circular surface allows the adapter assembly to be mounted in different rotational positions, thus adapting it to various installation situations or orientations of the field device. This allows for high mounting flexibility without compromising the functionality of the readout adapter or the readability of the display unit.

[0032] According to a further embodiment, the base body of the mechanical adapter can have an upper recess in the edge region. This recess can be designed to support or specify a predetermined orientation of the adapter arrangement on the field device. This allows a defined mounting position to be achieved, particularly with regard to the alignment of the readout adapter or the display unit.

[0033] Alternatively or additionally, the upper recess can serve to facilitate the removal of the adapter assembly from the field device, for example, by inserting a tool. This allows for easy removal of the adapter assembly without damaging the mechanical adapter or the field device. At the same time, the recess can be designed so that it does not significantly impair the mechanical stability of the adapter assembly when mounted.

[0034] Alternatively or additionally, a lower recess can be provided in the edge area of ​​the mechanical adapter's base body, opposite the upper recess. This lower recess can serve as a feedthrough for a cable of the readout adapter, with the readout adapter being either received or encapsulated within the recess when the adapter assembly is mounted on the field device. Furthermore, or alternatively, the lower recess can also facilitate the removal of the adapter assembly or the mechanical adapter from the field device, for example, by manual insertion or support. This further simplifies the handling of the adapter assembly during attachment and removal without significantly compromising its mechanical stability in the mounted state.

[0035] According to a further embodiment, the base body of the mechanical adapter can have at least one inner centering surface located on the rear side of the base body. The inner centering surface can be designed to rest centrally against a housing section of the field device when the adapter assembly is mounted.

[0036] The centering surface ensures radial alignment relative to the field device when attaching the adapter assembly. This guarantees that the mechanical adapter and any attached readout adapter are precisely and reproducibly aligned relative to the field device's readout or communication interface. The inner centering surface can be adapted to different field device housing shapes, such as cylindrical or rotationally symmetrical housing sections. This allows the adapter assembly to be used with various field device types without requiring complex adjustments. Simultaneously, the centering surface contributes to the mechanical stabilization of the adapter assembly in its mounted state.

[0037] According to a further embodiment, the readout adapter can have at least one suction cup designed to detachably attach the readout adapter to a front panel of the field device. Such a design can be particularly suitable for short-term or temporary applications, for example, for service or commissioning work in clean environments.

[0038] The use of one or more suction cups allows for quick and easy attachment of the readout adapter without requiring additional mechanical intervention or tools. This facilitates rapid access to measured values ​​or diagnostic information. Furthermore, the adapter assembly can be designed so that the suction cup mounting is supplemented or supported by additional mechanical means. This improves the positional stability and alignment of the readout adapter, even during extended use, such as continuous diagnostic, verification, or data acquisition tasks.

[0039] According to another embodiment, the fastening unit can be designed as a press-fit connection located in the edge region of the mechanical adapter. Such a press-fit connection can serve to fix the mechanical adapter to a housing section of the field device by positive or non-positive locking, without having to open the housing.

[0040] In preferred embodiments, the press-fit connection can be achieved by interaction with a clamping ring that is arranged around or attached to a front housing section of the field device. Alternatively, the press-fit connection can snap into an existing gap or recess in the housing. By utilizing the geometric properties of the device housing, a particularly stable and reproducible attachment can be achieved. Simultaneously, precise alignment of the readout adapter relative to a readout or communication interface of the field device can be supported.

[0041] This type of mounting design can be particularly suitable for long-term applications where the readout adapter needs to remain reliably attached to the field device for hours, days, or months. At the same time, the adapter assembly can be designed to be detachable and easily removed and reattached as needed, further simplifying service and maintenance processes.

[0042] According to a further embodiment, the mounting unit can have at least one lateral projection arranged in the edge region of the mechanical adapter. This lateral projection can serve to fix the adapter assembly to the field device in addition to or as an alternative to other mounting principles.

[0043] The placement of the lateral projection at the edge allows for flexible mounting that can adapt to different housing shapes and installation situations of the field device. In particular, the lateral projection helps to secure the mechanical adapter against unintentional slippage or rotation and to ensure a stable position of the readout adapter relative to a readout or communication interface of the field device.

[0044] According to a further embodiment, the lateral projection can be designed as at least one loop. Such a loop can be configured to interact with a strap, for example a hook-and-loop fastener or a cable tie, to attach the adapter assembly to the field device.

[0045] Using a loop in combination with a strap allows for a simple, flexible, and quick-release fastening. This makes the adapter arrangement suitable for both temporary and long-term applications. At the same time, it facilitates adaptation to different housing diameters or shapes of the field device without the need for special tools.

[0046] According to a further embodiment, the lateral projection can be configured as at least one retaining button. The retaining button can be designed to interact with an elastic band, in particular a rubber band, to fix the adapter assembly to the field device.

[0047] Such a design allows for a compact and form-fitting attachment, where the band is guided precisely by the retaining button. This ensures a reliable holding force while still allowing for quick assembly and disassembly of the adapter assembly. This embodiment can be particularly advantageous when the readout adapter needs to be repeatedly attached and removed for service or diagnostic purposes.

[0048] According to a further embodiment, the fastening unit can have a guide groove arranged on the front of the base body. The guide groove can be configured to interact with a band, in particular an elastic band, to fasten the adapter assembly to the field device.

[0049] The guide groove allows the belt to be guided and positioned precisely, preventing slippage during operation. This ensures consistent holding force and stable mounting of the adapter assembly. Simultaneously, the guide groove facilitates easy assembly and disassembly without the need for additional fasteners.

[0050] According to another embodiment, the mounting unit can have a feedthrough located on the front of the base body. This feedthrough can be used to guide a strap, such as a cable tie or rubber band, through the base body to secure the adapter assembly to the field device.

[0051] Using a feedthrough allows for a particularly secure and form-fitting fastening, as the strap or cable tie is guided precisely through the mechanical adapter. At the same time, this design offers high flexibility regarding the fastening materials that can be used and enables adaptation to different field device types.

[0052] According to a further embodiment, the mounting unit can be configured to attach the adapter assembly to the field device using fabric adhesive tape and / or adhesive tape. The fabric adhesive tape can, for example, be arranged around a front housing section of the field device to enable circumferential fixation.

[0053] The use of adhesive tapes can allow for quick, tool-free, and flexible mounting, especially for temporary applications or for field devices where other mounting methods are not possible. At the same time, this design can enable a gentle mounting process, as no permanent modifications to the field device are required.

[0054] According to a further embodiment, the base body of the mechanical adapter can have at least one lateral recess. The lateral recess can be designed to allow the adapter assembly to be detached from the field device without tools.

[0055] The lateral recess allows a user to initiate a release movement, for example, with their fingers or by simply bracing themselves against it. This enables quick and easy removal of the adapter assembly, even after extended use, without the need for special tools. At the same time, the recess can be designed in such a way that it does not significantly compromise the mechanical stability of the adapter assembly when mounted.

[0056] According to a further embodiment, the base body of the mechanical adapter can have a lever attachment surface arranged laterally at the edge. This lever attachment surface can serve to provide leverage for detaching the adapter assembly from the field device without tools.

[0057] By strategically designing a lever-like contact surface, removing the adapter assembly can be made more ergonomically easier, especially with adapter assemblies that are stuck or have been mounted for extended periods. This further improves handling during service or maintenance.

[0058] According to a further embodiment, the base body of the mechanical adapter can also have a second opening, which is designed to reveal at least one indicator light of the readout adapter and / or to reveal or operate a control panel and / or a display of the readout adapter. This allows a user to check the functional status or communication readiness of the readout adapter without disassembling the adapter assembly. This can be particularly advantageous in diagnostic, service, or monitoring applications.

[0059] According to a further embodiment, the readout adapter can have an optical infrared transmitter and receiver and / or an NFC readout interface. Such a configuration can enable contactless communication between the readout adapter and the field device.

[0060] By using optical or wireless readout interfaces, measured values, diagnostic information, or device states can be accessed without establishing an electrical connection to the field device. This makes the adapter arrangement particularly suitable for applications where existing electrical interfaces or the integration of the field device into a control system should not be modified.

[0061] Another aspect concerns a mechanical adapter, which can be manufactured using additive manufacturing and / or injection molding. Additive manufacturing allows for the rapid and cost-effective production of the mechanical adapter, particularly for prototypes, small production runs, or application-specific designs.

[0062] Alternatively or additionally, the mechanical adapter can be manufactured using injection molding. This can be particularly advantageous for series production, ensuring reproducible quality and high mechanical stability. The choice of manufacturing process can depend on requirements regarding quantity, material properties, or service life.

[0063] The ability to use different manufacturing processes allows the mechanical adapter to be flexibly adapted to various field devices, housing shapes or operating conditions, making the adapter arrangement as a whole economical and versatile.

[0064] Another aspect concerns a measurement system that may include an external readout device and an adapter arrangement as described previously. The external readout device may be configured to interact with the field device, either directly or indirectly via a readout adapter, to read out measured values ​​from the field device.

[0065] The interaction can be achieved in such a way that neither the electronics, circuitry, nor wiring of the field device are affected or altered. This allows access to measured values, diagnostic information, or status data while the field device remains integrated into an existing automation or control system without modification. The measurement system is therefore particularly suitable for service, diagnostic, verification, or monitoring applications.

[0066] According to another embodiment, the external readout device can be a mobile terminal, a portable service device, a computer, an industrial handheld, a gateway, and / or a cloud-connected evaluation system. This design allows the measurement system to be used flexibly in various application scenarios, such as in the field, during commissioning, maintenance work, or for remote evaluation of measurement or diagnostic data.

[0067] The use of different external reading devices can also support easy integration into existing IT or IoT infrastructures and facilitate access to field device data for different user groups.

[0068] According to another embodiment, the measuring system can include the field device itself. The field device can be configured as a flow meter, a level meter, a pressure gauge, a temperature meter, and / or an analytical instrument.

[0069] Integrating the field device into the measurement system enables a holistic view of the measurement and readout functions. Simultaneously, the measurement system can be used for different measured variables and applications without requiring any adjustments to the electrical interfaces of the field device.

[0070] According to another embodiment, the field device can have a housing designed as a single-chamber housing, a wall-mounted housing, or a cylindrical housing. Such a housing design is particularly common in industrial field devices.

[0071] By adapting the adapter arrangement to different housing shapes, the measuring system can be used for various device platforms. This allows for high compatibility with existing field devices without requiring any design modifications to the field device itself.

[0072] Another aspect concerns the use of an adapter arrangement, as previously described, for the detachable mounting of a readout adapter to a field device. This adapter arrangement can be used to read measured values ​​from the field device without requiring any modifications to the electrical wiring, electronics, or circuitry of the field device.

[0073] The adapter assembly allows a readout adapter to be temporarily or permanently attached to the field device, for example, for service, diagnostic, monitoring, or verification purposes. At the same time, the adapter assembly enables easy attachment and removal of the readout adapter, so that the ongoing operation of the field device is not disrupted. The use of the adapter assembly can be particularly suitable for applications where additional measurement or status information from the field device needs to be acquired, information that is not transmitted, or not permanently transmitted, to a higher-level control system. This allows for a flexible expansion of the readout and monitoring capabilities of existing field devices.

[0074] To further illustrate the invention, it is described with reference to a figure. This embodiment is to be understood only as an example, not as a limitation. Brief description of the characters

Detailed description of the embodiment

[0076] Fig. Figure 1a shows a schematic top view of a measuring system 1 according to one embodiment. The measuring system 1 comprises an adapter arrangement 10, which is mounted on a field device 500. The adapter arrangement 10 has a mechanical adapter 100 with a base body 110, which is positioned on a front panel of the field device 500. The base body 110 has a first opening 150 and a second opening 155, through which, in the mounted state, a display unit of the field device 500 and at least one indicator light of a readout adapter can remain visible.

[0077] The adapter assembly 10 serves to detachably mount a readout adapter 200 to the field device 500, enabling the reading of measured values, diagnostic information, or operating states of the field device without altering the electrical wiring, electronics, or integration of the field device into a higher-level control system. This allows additional access to internal device information, for example, for service, diagnostic, verification, or monitoring purposes, while maintaining the ongoing operation of the field device.

[0078] Fig. Figure 1b shows a schematic perspective view of a field device 500 with a cylindrical housing. An adapter arrangement 10 is attached to the field device 500, as shown in Fig. Figure 1a shows an attached mechanical adapter 100 and a readout adapter 200. The mechanical adapter 100 is positioned on a front housing section of the field device 500 and holds the readout adapter 200 in a defined position relative to a front panel 510 of the field device. The illustration demonstrates that the adapter arrangement 10 can also be used with field devices that have a rotationally symmetrical or cylindrical housing, whereby the readout adapter 200 remains reliably positioned at a readout or communication interface of the field device.

[0079] Fig. Figure 1c shows a schematic top view of a field device 500 with a single-chamber housing, on which an adapter arrangement 10 with a readout adapter 200 is mounted. The mechanical adapter 100, as shown in Fig. As shown in Figure 1a, the adapter can be arranged on the front panel of the field device 500 and allows the readout adapter 200 to be aligned relative to a display unit of the field device. The figure illustrates that the adapter arrangement 10 is suitable for field devices with different housing designs and enables a space-saving arrangement of the readout adapter without significantly impairing the operability or readability of the field device.

[0080] Fig. Figure 1d shows a schematic top view of a field device 500 without the adapter assembly mounted. The illustration serves to demonstrate the geometric design of the field device 500, in particular the arrangement of the front panel 510 and a display unit 550. Fig. 1d thus forms a reference representation, based on which the positioning and orientation of the adapter arrangement in the Fig. 1a to 1c can be traced.

[0081] Fig. Figure 2a shows a schematic rear view of an adapter arrangement 10, comprising a mechanical adapter 100 with a base body 110, the rear side 115 of which faces the field device 500 when mounted. The mechanical adapter 100 has a circumferential edge region 130, in which, among other things, an upper recess 135 may be provided.

[0082] The base body 110 has a receiving area 120 in which a readout adapter 200 is arranged. The readout adapter 200 is inserted into the receiving area 120 such that, when assembled, it is positioned between the mechanical adapter 100 and the field device. The readout adapter 200 may have a contact or coupling surface facing the field device and serves to receive or transmit measurement, diagnostic, or communication signals from the field device.

[0083] As can be seen in the rear view, the readout adapter 200 has at least one suction cup 210, which is designed for detachable attachment to a front panel or window surface of the field device. The suction cup 210 facilitates initial positioning and coupling of the readout adapter to a corresponding interface of the field device, while the mechanical adapter 100 provides additional mechanical fixation and alignment.

[0084] Furthermore, internal centering surfaces 118 are formed on the rear side 115 of the base body 110, which are designed to rest centrally against a housing section of the field device when the adapter assembly is mounted. This allows a defined radial alignment of the adapter assembly 10 relative to the field device to be achieved, in particular for the reproducible positioning of the readout adapter 200 relative to an optical or contactless communication interface of the field device.

[0085] Fig. Figure 2b shows a schematic perspective view of a readout adapter 200, which is designed as a self-contained assembly and may have a communication interface to the field device, for example an optical infrared transmitter and receiver RX / TX or alternatively a wireless readout interface, such as an NFC interface. Additionally, the readout adapter 200 may have at least one indicator light 220, which indicates an operating or communication status of the readout adapter.

[0086] Fig. Figure 2c shows a schematic rear view of a mechanical adapter 100. The mechanical adapter 100 can essentially be configured as a cap with a substantially cylindrical recess on its rear side and a rim 130. The outer contour of the mechanical adapter 100 can be of any shape. It should be noted that the recess on the rear side can fit snugly onto the housing of the field device 500. Alternatively or additionally, a clamp or clip can be provided, which can be truncated at the top and bottom and attached to the field device 500 at a plurality of points or sides. In other words, the mechanical adapter 100 can have a substantially disc-shaped base body 110 with a circumferential or at least partially circumferential rim 130.In the peripheral area 130, one or more mounting units can be provided for detachably attaching the mechanical adapter to a field device. The illustration clarifies the compact design of the mechanical adapter and its suitability for receiving and positioning a readout adapter.

[0087] Fig. Figures 3a to 3d show schematic representations of a mechanical adapter 100 with or without the inserted readout adapter 200 in different views, in particular a perspective view, a rear view, and a top view. The figures illustrate the geometric design of the mechanical adapter 100 and its suitability for receiving and positioning the readout adapter 200.

[0088] The mechanical adapter 100 has a base body 110 with a receiving area 120 in which the readout adapter 200 can be held. The illustrations show that the mechanical adapter is designed to be adapted to different geometric designs of front panels or window arrangements of field devices. In particular, the mechanical adapter can compensate for tolerances in diameter and material thickness of different housing designs, thus enabling secure mounting on both newer and older housing variants.

[0089] Furthermore, they show Fig. 3a to 3d, that the mechanical adapter may have 100 lateral recesses 160 and / or lever contact surfaces 165, which facilitate the tool-free removal of the mechanical adapter from the field device. These geometric features allow a user, for example, to pull the mechanical adapter off the field device with their fingers by applying a targeted counterforce to an internal housing area of ​​the field device. In this way, easy removal of the mechanical adapter is made possible, even if it has been mounted on the field device for an extended period of time.

[0090] The differing views of Fig. Figures 3a to 3d further illustrate that the mechanical adapter 100 has a compact, dimensionally stable design that supports both reliable holding force and easy handling during attachment and removal. This makes the mechanical adapter particularly suitable for applications where a readout adapter needs to be repeatedly mounted and dismounted, for example, for service, diagnostic, or verification purposes, without the need for tools.

[0091] Fig. Figures 4a to 4d show schematic representations of a Field Device 500 with a single-chamber housing in different views. In particular, a top view, a side view, and other views illustrating the external geometry and construction of the field device are shown.

[0092] The figures show the field device 500 with a front panel 510 on which a display unit 550 is arranged. The illustration clarifies the position and dimensions of the front panel 510 as well as its spatial relationship to the rest of the field device housing.

[0093] Furthermore, a front housing section 515 is discernible, which is suitable for a detachable fastening of an adapter arrangement.

[0094] The differing views of Fig. Figures 4a to 4d further illustrate the geometric boundary conditions of the single-chamber housing, in particular with regard to the shape and position of the front panel 510 and the transitions to adjacent housing sections. These illustrations serve as a reference for attaching a mechanical adapter to the field device and show that the adapter arrangement is designed to be used on field devices with a single-chamber housing without opening the housing or exposing internal components.

[0095] The figures further illustrate that the adapter arrangement 10 can be positioned on the front of the field device 500, so that the display unit 550 remains at least partially visible even when the adapter arrangement is mounted and the operability of the field device is not significantly impaired.

[0096] Fig. Figure 4e shows a schematic side view of a mechanical adapter 100, for example, for a cylindrical housing of a field device 500. In this illustration, the base body 110 and the edge region 130, by means of which the mechanical adapter can be attached to a field device, are particularly visible. The side view clarifies the height variations and contours of the base body 110, which are adapted to the geometry of a single-chamber housing. In particular, the lug XX is visible, which engages in a gap between the front cover and the housing body of the field device when the adapter is placed on the device.

[0097] Furthermore, in Fig. 4e The inner surfaces of the mechanical adapter are visible, which can serve for centering against a housing section of the field device. The geometry shown enables a defined positioning of the mechanical adapter relative to the front panel of the field device and helps to ensure that a readout adapter can be arranged in a reproducible position relative to a display unit or a communication interface.

[0098] Furthermore, the side view illustrates that the mechanical adapter 100 is designed to be mounted and removed without opening the field device 500. The depicted contours ensure a secure hold of the adapter, even over extended periods, while simultaneously allowing for tool-free removal by applying targeted manual force to designated areas.

[0099] Fig. Figure 4f shows a schematic side sectional view of a measuring system 1 with a field device 500 in the form of a single-chamber housing and an adapter assembly 10 mounted on it. The mechanical adapter 100 is located on the front of the field device 500 and rests against a front housing section of the field device. A readout adapter is positioned between the mechanical adapter 100 and the field device 500, which is mechanically held by the adapter assembly and aligned relative to a communication interface of the field device.

[0100] The illustration clarifies that, in single-chamber housings of the field device, a direct snap-fit ​​or click-fit attachment of the mechanical adapter to the housing is not necessarily required. In the illustrated embodiment, therefore, an additional component, in particular a ring, is provided, which serves as a counter-structure and enables a positive-locking or snap-fit ​​interaction with the mechanical adapter. Alternatively or additionally, the adapter assembly can be fixed to the field device using other fastening elements, such as tape-based or adhesive fasteners.

[0101] Fig. Figure 4f thus illustrates the interaction of the adapter arrangement 10 with the geometry of the single-chamber housing and shows that even with housings lacking suitable locking or undercut structures, a stable mechanical fixation of the readout adapter can be achieved without opening the field device housing or altering electrical connections. The mechanical adapter 100 engages the field device in a form-fitting and surface-mounted manner, thus achieving a reliable mechanical fixation of the readout adapter without the need to open the field device housing or alter electrical connections.

[0102] Furthermore, in Fig. 4f. It is evident that the adapter arrangement is designed so that the readout adapter can be held in a defined position relative to a device interface, in particular an optical or contactless communication interface. This ensures a stable and reproducible communication connection, even during prolonged use or when subjected to mechanical stresses, for example from connected lines or cables.

[0103] The illustrated arrangement further demonstrates that the adapter assembly is suitable for both temporary and long-term applications. The mechanical adapter can securely hold the readout adapter in position for extended periods while simultaneously allowing for quick removal and reattachment of the adapter assembly. In this way, the illustrated solution is particularly suitable for service, diagnostic, monitoring, or verification tasks where reliable access to measured values ​​or device states is required without disrupting the ongoing operation of the field device.

[0104] Fig. Figure 5a shows a schematic perspective view of a mechanical adapter 100 with lateral projections 180, which are designed as loops 180a. The loops are an integral part of the edge region of the mechanical adapter and serve to accommodate a strap for additional or alternative attachment of the adapter assembly to the field device. The base body of the mechanical adapter still has the first opening and the second opening, so that indicator elements and signal lights can remain visible in the mounted state.

[0105] Fig. Figure 5b shows a schematic rear view of an adapter arrangement 10 with a mounted readout adapter 200, wherein the mechanical adapter 100 is attached to a field device 500 by means of the side loops 180a, as shown in Fig. Figure 5d shows how the attachment is secured. The illustration demonstrates that the loops allow for flexible positioning of the fastening device, thereby enabling reliable fixation of the readout adapter relative to the display unit of the field device. At the same time, the front of the field device remains accessible and uncluttered.

[0106] Fig. Figure 5c shows a schematic perspective view of a measuring system 1 in which the adapter arrangement 10 is attached around a housing section of the field device 500 by means of a strap, in particular a hook-and-loop fastener. The loops 180a guide the strap in such a way that the adapter arrangement is held securely even during extended periods of use. This design is particularly suitable for applications where stable fixation is required for hours, days, or months, for example, for diagnostic, monitoring, or data recording tasks, without requiring any modifications to the field device.

[0107] Fig. Figure 5d shows another schematic view of a measuring system, in which the adapter arrangement 10 is in the same orientation and with the same mounting method as in Fig. The illustration shows the 5c mounted on the field device 500, with a rear view of the field device. The illustration demonstrates that the mounting via lateral loops allows for a high degree of flexibility regarding the installation position. This enables the adapter arrangement to be used regardless of the orientation of the field device or the position of the display unit. Simultaneously, a dimensionally stable and precise positioning of the readout adapter relative to an optical or contactless interface of the field device is achieved.

[0108] Through the in Fig. 5a to Fig. Figure 5d illustrates that the adapter arrangement is suitable for both temporary and long-term applications. The combination of a mechanical adapter and strap-based fastening allows for easy installation, reliable holding force even under harsh environmental conditions, and quick, tool-free removal without affecting the electrical or system integration of the field device.

[0109] Fig. Figure 6a shows a schematic side view of a measuring system 1 in which an adapter arrangement 10 is mounted on a field device 500. The adapter arrangement has lateral projections in the form of loops 180a through which a fastening element, in particular a cable tie 80b, is guided. The illustration shows that the fastening element can be inserted into the loop from the front of the field device, thus enabling easy mounting of the adapter arrangement.

[0110] Fig. Figure 6b shows a schematic rear view of a field device 500 with an attached adapter assembly, in which the fastening element is guided along a rear housing section. It can be seen that the fastening element can be positioned between the field device housing and a mounting surface or a rear structure without impairing the function or accessibility of the field device. This design is particularly suitable for wall-mounted field devices or confined installation situations.

[0111] Fig. Figure 6c shows a schematic perspective view of a measuring system 1 in which the adapter arrangement 10 is attached around a housing section of the field device 500 by means of a cable tie 80b. The lateral loops 180a guide the fastening device in such a way that a uniform contact force acts on the mechanical adapter. This ensures a stable position of the readout adapter relative to the interface of the field device, even during extended periods of use or under external influences such as cable weight or vibrations.

[0112] Fig. Figure 6d shows another schematic view of a measuring system 1 in which the adapter arrangement 10 is mounted on the field device 500 in an alternative orientation. The illustration demonstrates that the fastening using cable ties can be carried out regardless of the installation position of the field device 500. Particularly with wall-mounted or overhead field devices, this method allows for reliable fixation of the adapter arrangement without the need for special housing designs or additional components.

[0113] Fig. Figure 6e shows a schematic front view of a measuring system 1 with the adapter assembly 10 mounted. This illustration shows that, despite the tape-based mounting, the adapter assembly maintains a defined orientation relative to the front panel and the display unit of the field device 500. At the same time, the display elements of the field device 500 and the readout adapter 200 remain accessible and visible through the mechanical adapter 100. The figure illustrates that the adapter assembly 10 remains detachable even with long-term mounting and can be quickly removed or reattached as needed.

[0114] The in Fig. 6a to Fig. The embodiments shown in Figure 6e illustrate that the adapter arrangement 10 is particularly suitable for demanding operating conditions, such as wall-mounted field devices 500, elevated temperatures, vibrations, or extended operating times. The use of strap-based fasteners in combination with lateral loops ensures reliable mechanical fixation without affecting the electronics, cabling, or system integration of the field device.

[0115] Fig. Figure 7a shows a schematic perspective view of a mechanical adapter 100 in a state separated from the field device. The mechanical adapter has lateral projections 180c in the form of retaining buttons or mounting pins, which are arranged in the edge region of the base body. These lateral projections serve to receive a flexible fastening element, in particular a rubber band or a comparable elastic band, in a form-fit or force-fit manner. The illustration demonstrates that the mechanical adapter can be handled independently of the field device and is already structurally prepared for a band-based additional fastening.

[0116] Fig. Figure 7b shows a schematic perspective view of a measuring system 1 in which the mechanical adapter 100 is mounted on a field device 500. In this configuration, the mechanical adapter is additionally secured to the field device by a rubber band 80c via the lateral projections 180c. The readout adapter is thus arranged in a defined position relative to the display unit of the field device. The figure illustrates that the band-supported fastening provides a stable mounting, which is particularly suitable for extended operating times, for example in service, diagnostic, or monitoring applications, without the need to open the housing of the field device.

[0117] Fig. Figure 7c shows a side view of a measuring system 1 in which the mechanical adapter 100 is mounted on a field device 500 and additionally secured by means of a fabric adhesive tape 81. The fabric adhesive tape is wrapped around a housing section of the field device and exerts an additional holding force on the mechanical adapter. This embodiment is particularly suitable for applications where elastic bands cannot be used, or can only be used to a limited extent, due to geometry, installation position, or environmental conditions. The illustration shows that the mechanical adapter remains accessible despite the additional securing and no covering of essential device areas is required.

[0118] Fig. Figure 7d shows another side view of a measuring system 1 in which the mechanical adapter 100 is attached to the field device 500 by means of an adhesive tape 81a. The adhesive tape is arranged such that it secures the mechanical adapter against unintentional detachment without impairing the function of the field device or access to its display. This embodiment represents an alternative or supplementary fastening option, particularly for installations with limited space, wall-mounted field devices, or applications with increased environmental influences. The figure illustrates that different fastening concepts can be flexibly combined to ensure reliable positioning of the readout adapter over extended periods.

[0119] Fig. Figure 8a shows a schematic perspective view of a mechanical adapter 100. The mechanical adapter 100 has a guide groove 182 and a feedthrough 184 in its edge region. The guide groove 182 is located on the front of the base body and serves to guide a flexible fastening element, in particular a rubber band or a cable tie, in a defined position. The feedthrough 184 is designed as a passage in the base body and allows a fastening element or a cable to be passed through the mechanical adapter. The illustrated design allows for different fastening options without requiring additional components on the field device.

[0120] Fig. Figure 8b shows a schematic representation of a measuring system 1 with a field device 500 to which the mechanical adapter 100 is mounted. In the configuration shown, a fastening element 80a is guided through the feedthrough 184 and along the guide groove 182. This secures the mechanical adapter 100 to the field device 500 in a positive and non-positive manner. The figure illustrates that the adapter arrangement can be securely fastened even under difficult mounting conditions, for example, with wall-mounted field devices or in confined spaces, without opening the housing of the field device or altering electrical connections.

[0121] Fig.Figure 8c shows another schematic representation of a measuring system 1 with a field device 500 and an adapter assembly attached to it. In this embodiment, a fastening element 80b is guided over the feedthrough 184 and placed around a housing section of the field device 500. The illustration demonstrates that the combination of feedthrough and guide geometry enables a stable fastening suitable even for extended periods of use. At the same time, the adapter assembly remains detachable, so that it can be removed or reattached as needed, for example, for service, diagnostic, or monitoring purposes.
