Title:
導電性媒体を検出するためのセンサ装置及び当該センサ装置を動作させるための方法
Document Type and Number:
Japanese Patent JP7143416
Kind Code:
B2
Abstract:
A sensor device for detecting liquid, in particular in a controller of a steering system of a vehicle, includes at least one sensor element and a testing unit. The sensor element is electrically connected to the testing unit. The testing unit has a signal transmitter, connected to the sensor element, that is configured to generate an electrical test signal, and a signal receiver, connected to the sensor element, that is configured to detect a reaction signal for the electrical test signal. The signal transmitter and the signal receiver are each connected at high impedance to the at least one sensor element. The testing unit is configured to detect the reaction signal at least at a time as a first reaction signal for which the electrical test signal has been generated in order to infer a presence of the medium.
