BRIEF DESCRIPTION OF THE DRAWINGS

[0036] FIG. 1 shows a transmitter 1 comprising a transmitter housing and a sensor protruding downward from the transmitter housing. The housing has an upper side with a viewing window that allows a user of the transmitter to look inside the transmitter. Located in the housing behind the viewing window is a device unit 2, which is connected to the sensor. The device unit 2 allows the sensor to be controlled and the measurement values measured by the sensor to be checked. The housing further includes a cable duct arranged laterally in order to guide at least a first cable 3 into the interior of the housing. A detailed view of the device unit 2 without the housing and without the connection to the sensor is illustrated in FIG. 2.

[0037] The device unit 2 comprises an interface module 10, which is shown in FIG. 3 based on an exploded drawing. The interface module 10 comprises a communication unit 11, a holding element 12 and a connection 13 for connecting the communication unit 11 to the holding element 12.

[0038] The communication unit 11 is suitable for being communicatively connected to an electronics module 20 of the device unit 2. As a result of the communicative connection, the communication unit 11 can input information to the device unit 2 by a user and output information from the device unit 2 to a user. The user can thus communicate with the electronics module 20 of the device unit, for example, to control the sensor or to check the function of the sensor.

[0039] The holding element 12 is mechanically connected to the communication unit 11 by means of the connection 13. The communication unit 11 and the holding element 12 are designed to receive the connection 13.

[0040] In the embodiment shown in FIG. 3, the connection 13 is a joint, or more precisely a hinge. In an alternative embodiment, however, the connection could also be formed by a different type of joint. The joint allows the communication unit 11 to move relative to the holding element 12. Thus, the communication unit 11 can be moved relative to the holding element 12 between a first folding position A and a second folding position B.

[0041] The interface module 10 further comprises a tensioning element 18 suitable for moving the communication unit 11 relative to the holding element 12 from the first folding position A into a second folding position B. The tensioning element 18 can be a spring, for example, as is shown in FIG. 3. Alternatively, the tensioning element 18 could also be a flexible metal strip. Other elements that are able to serve the same purpose could also be used as the tensioning element 18. The tensioning element 18 makes it possible for the user not to personally have to move the communication unit 11 into the second folding position B or to hold it in this folding position. Thus, the use of the interface module 10 becomes more convenient.

[0042] As is shown in FIG. 3, the interface module 10 may comprise a locking device 16. Said locking device is suitable for locking the communication unit 11 relative to the holding element 12 in the first folding position A. The locking device 16 comprises a first locking element 17 which is fastened to the communication unit 11 and a second locking element 27 which is fastened to the holding element 12. The locking device 16 can also comprise a plurality of first locking elements 17 and a plurality of second locking elements 27. The first and second locking elements 17, 27 are complementary to one another. The first and second locking elements 17, 27 can each be an elastic detent hook, for example. Alternatively, the locking elements 17, 27 could also be implemented by mutually attracting magnetic elements. The locking device 16 prevents the communication unit 11 from undesirably moving out of the folding position A, for example due to the gravitational forces or tensioning forces acting on the communication unit 11. As a result of the locking elements 17, 27, the use of the interface module 10 thus becomes even more convenient.

[0043] In FIG. 3, the holding element 12 is shown in an annular shape and comprises a fastening element 14. The annular holding element 12 can be connected by means of the fastening element 14 to an annular fastening element 24 of the electronics modules 20, which are shown in FIG. 4.

[0044] The two fastening elements 14, 24 are complementary and allow the holding element 12 to rotate relative to the electronics module 20 between a first rotational position C and a second rotational position D when the fastening elements 14, 24 are connected to one another. The rotation of the holding element 12 will be discussed later (see also FIG. 6). Depending on the arrangement of the device unit 2, this allows a user to rotate the holding element 12 so that the communication unit 11 can be operated or read more easily. This also makes the use of the interface module 10 more convenient.

[0045] As shown in FIG. 3, the communication unit 11 may comprise a tooth 15. The tooth 15 is suitable for engaging in at least a first recess 25 of the electronics module 20 which is complementary to the tooth 15 and which can be seen in FIG. 4. A rotation of the holding element 12 relative to the electronics module 20 can thus be prevented when the tooth 15 engages in the recess 25. A user is thus protected from accidentally turning the communication unit 11 relative to the electronics module 20. This also makes the use of the interface module 10 more convenient.

[0046] FIG. 4 shows the electronics module 20 of the device unit 2 with the first recess 25 and a second recess 26. The first recess 25 of the electronics module 20 is suitable for receiving the tooth 15 of the communication unit 11 when the holding element 12 is in the first rotational position C relative to the electronics module 20 (see also FIGS. 5 and 6). The second recess 26 of the electronics module 20 is suitable for receiving the tooth 15 of the communication unit 11 when the holding element 12 is in the second rotational position D relative to the electronics module 20 (see also FIGS. 7 and 8). The electronics module 20 can also have a plurality of recesses 25; these are arranged along an edge of the electronics module 20, for example, as can be seen in FIG. 4.

[0047] As is shown in FIG. 4, the electronics module 20 has an electronic connection point 29 suitable for receiving a first cable 3. The first cable 3 can be electrically connected to the electronic connection point 29 in order to, for example, supply power to the electronics module 20 or to transmit measurement data via the first cable 3. The electronics module 20 also has an opening 30 suitable for receiving the first cable 3. Thus, the first cable 3 can be easily connected to the electronic connection point 29 through the opening 30.

[0048] FIG. 5 shows the device unit 2 in which the interface module 10 is connected to the electronics module 20. The communication unit 11 is in the first folding position A. The holding element 12 is in the first rotational position C.

[0049] FIG. 6 shows the device unit 2, with the communication unit 11 in the second folding position B. In this folding position, the opening 30 and the electronic connection point 29 of the electronics module 20 are simultaneously accessible to the user. Thus, the user can easily guide the first cable 3 through the opening 3 and connect it to the electronic connection point 29 of the electronics module 20.

[0050] FIG. 7 shows the device unit 2, with the holding element 12 in the second rotational position D. An arbitrary number of further rotational positions can be defined on the annular fastening element 24 of the electronics module 20 based on further recesses in order to enable an ideal orientation of the communication unit 11 for the user in the first folding position A. For example, eight recesses may be formed on the fastening element 24 of the electronics module. Each recess is suitable for receiving the tooth 15 of the interface module 10. FIG. 7 further shows a second cable 4 connecting the communication unit 11 to the electronic connection point 29 of the electronics module 20.

[0051] FIG. 8 shows the device unit 2, with the holding element 12 in the second rotational position D and the communication unit 11 in the first folding position A.

[0052] The mounting method of the device unit 2 for the transmitter 1 is described below.

[0053] In a first mounting step, the holding element 12 of the interface module 10 is fastened to the electronics module 20. This can be done by pressing the fastening element 14 of the holding element 12 onto the fastening element 24 of the electronics module 20. In this embodiment variant, the fastening element 14 or the fastening element 24 is preferably designed to be elastic.

[0054] As is apparent from arrow I in FIG. 6, the communication unit 11 of the interface module 10 is subsequently moved from the first folding position A into the second folding position B. This movement can be caused by the tensioning element 18, which is released by the release of the locking device 16. During this step, the tooth 15 of the interface module 10 detaches from the first recess 25 of the electronics module 20. This step allows the electronic connection point 29 of the electronics module 20 to become accessible to an operator for the connection to the first cable 3 and the second cable 4. During or after this step, the first cable 3 can be electrically connected to the electronic connection point 29 in order to, for example, supply the device unit 2 with power. Likewise, during or after this step, the communication unit 11 can be connected to the electronics module 20 by the second cable 4 in order to supply the communication unit 11 with power or to exchange information from the device unit 2 with the communication unit 11.

[0055] Optionally, after the step of moving the communication unit 11 of the interface module 10 into the second folding position B, a step of rotating the holding element 12 of the interface module 10 from a first rotational position C into a second rotational position D can be carried out, as is illustrated by arrow II. in FIG. 6.

[0056] In a further step, which is indicated by arrow III in FIG. 7, the communication unit 11 of the interface module 10 is moved back into the first folding position A. The tooth 15 of the interface module 10 again engages in the first recess 25 in this process if the holding element 12 has remained in the first rotational position C. However, the tooth 15 of the interface module 10 engages in the second recess 26 if the holding element 12 has been rotated into the second rotational position D.

[0057] In an alternative embodiment, the communication unit 11 may be wirelessly connected to the electronics module 20, using a Bluetooth connection, for example.
