| 摘要 |
The invention relates to a detector assembly, comprising a monitoring body having an outer surface, an electrically conductive detector layer applied to the outer surface of the monitoring body, and an evaluating circuit assembly connected to the detector layer in an electrically conductive manner, wherein the evaluating circuit assembly comprises a signal generator and interacts with the detector layer in such a way that, during a normal operation state of the evaluating circuit assembly, when the evaluating circuit assembly applies a voltage, a nominal current is conducted by means of the detector layer and a indicative operating parameter is monitored by the evaluating circuit assembly and that, when the indicative operating parameter changes, the evaluating circuit assembly enters a signal operation state, in which a signal is generated by means of the signal generator. |
