Abstract
An add-on module for a sensor, such as a fill and/or limit level sensor, comprising a coupling unit, which is arranged to be communicatively couplable to at least one predetermined sensor, and a control unit, which is configured to enable and/or disable data processing of the at least one predetermined sensor. Furthermore, the invention also relates to a sensor unit for detecting a fill level and/or limit level, comprising at least one sensor, and such an additional module, as well as a method for controlling such a sensor unit.
Claims20
An add-on module for a fill level and/or limit level sensor, comprising:
- coupling circuitry configured to be communicatively coupled to at least one predetermined sensor;
- and
- control circuitry configured to enable and/or disable data processing of the at least one predetermined sensor,
- wherein the add-on module is configured to retrofit the at least one predetermined sensor to extend functions of the at least one predetermined sensor with tamper protection.
A method for controlling a sensor group configured to detect a filling level and/or limit level including at least one predetermined sensor and an add-on module, wherein the add-on module is configured to enable and/or disable data processing of the at least one predetermined sensor, wherein the add-on module is configured to retrofit the at least one predetermined sensor to extend functions of the at least one predetermined sensor with tamper protection, the method comprising:
- operating the at least one predetermined sensor in normal operation;
- coupling the add-on module to the at least one predetermined sensor;
- checking whether the add-on module and the at least one predetermined sensor are assigned to each other;
- enabling sensor setting and/or data processing of the at least one predetermined sensor when the add-on module and the at least one predetermined sensor are associated with each other.
