摘要:
Embodiments herein provide detection of contamination at one or more contacts of a sensor system. The sensor system includes a sensor assembly and an electronics assembly communicatively coupled together by one or more contacts. The sensor assembly passes a sensor signal to the electronics assembly for further processing. The electronics assembly includes a detection contact for detecting contamination on or near one or more contacts of the sensor assembly and/or the electronics assembly. A switch selectively couples the detection contact to a bias voltage during a measurement mode and to a reference voltage during a detection mode, the reference voltage being different from the bias voltage. A method of contamination detection includes switching the electronics assembly between the measurement mode and the detection mode, and monitoring for a change in the output signal received by the electronics assembly.
