METHOD FOR REAL-TIME MONITORING OF THE OPERATING STATE OF A CAPACITIVE SENSOR

摘要

The invention relates to a method for real-time monitoring of the operating state of a capacitive sensor capable of being mounted on a rotating machine, and connected to an electronic measurement module via a high frequency transmission line, this method comprising the steps of: - generation within the electronic module of a compensation signal in parasitic effects capacity of the transmission line and the sensor, - generation within the electronic module of a compensation signal in effect conductance interference from the transmission line and the sensor, - taking a signal representative of the capacitance compensation and a signal representative of the conductance compensation so as to determine a point of operation of the sensor, - analysis of the operating point to check if it is in a predetermined area.
