Abstract
A device for determining and/or monitoring the temperature of a medium includes a temperature sensor for detecting the temperature and an electronics module, wherein the temperature sensor includes a temperature-sensitive sensor element in electrical contact with the electronics module via at least one connection line. The device further includes a diagnostic unit with a separate device for temporal variation of a power of an input signal, by which the temperature sensor or at least one component of the device can be acted upon, and which diagnostic unit is configured to determine, based on an output signal of the temperature sensor in response to the input signal, a statement about a thermal coupling of the device to the medium. A method for operating the corresponding device is also disclosed.
