Abstract
In the method for monitoring the sensor device (,), which supplies an analog output signal over a bidirectional output line (,) to an analysis unit (,) for evaluation, a predetermined test signal is applied to a sensor output in a monitoring phase, which is received in the analysis unit (,) and evaluated. In order to initiate the monitoring phase at any arbitrary time without the need of an additional connecting line between the sensor device and the analysis unit, a trigger signal of a predetermined trigger level is transmitted by the analysis unit (,) to the sensor device (,) over the output line (,) and is detected in the sensor device, which generates the predetermined test signal and transmits it to the analysis unit (,) over the bidirectional connecting line (,). A sensor device and connected analysis unit designed to perform this method are also described.
