Field device
A field device with a housing, a sensor, and an electronic unit arranged in the housing, with the field device comprising a radio module that can be connected to the electronic unit and removed therefrom.
1. A field device comprising a housing, a sensor, and an electronic unit arranged in the housing and a radio module that can be connected to the electronic unit and disconnected therefrom, wherein the radio module comprises a control element for turning on and off the radio module, with such control element mechanically arranged so it can be operated only when the radio module is disconnected.
2. The field device according to claim 1 , wherein the control element is accessible only when the radio module is removed.
3. The field device according to claim 1 , wherein the radio module is arranged in a display and control unit comprising electronic components for displaying measurements and configuring the field device.
4. The field device according to claim 3 , wherein the display and control information is transmitted by wire between the display and control unit and the electronic unit.
5. The field device according to claim 3 , wherein the display and control information is wirelessly transmitted via the radio module between the display and control unit and the electronic unit.
6. The field device according to claim 1 , wherein the radio module is mechanically anchored and the control element is arranged at the bottom of the radio module such that the control element is accessible only after releasing the anchoring and removing the radio module from its housing.
7. The field device according to claim 1 , wherein the field device can be mechanically locked and secured from unauthorized access.
8. The field device according to claim 1 , further comprising wherein the radio module comprises a battery for the partial or complete energy supply of the radio module.
9. The field device according to claim 1 , further comprising wherein the radio module comprises a timer unit.
10. The field device according to claim 9 , wherein after activation the radio module remains activated for a predetermined period, such period programmed into the timer unit, and then is automatically turned off by the timer unit.
11. The field device according to claim 5 , wherein the electronic unit and the display and/or control unit each comprise a radio module, with the radio modules being embodied such that they receive radio signals from another radio module and transmit such radio signals.
12. The field device according to claim 1 , wherein the radio module or the display and control unit can be arranged in a housing.
