Abstract
A method for real-time monitoring of an operational state of a capacitive sensor capable of being mounted on a rotating machine, and connected to an electronic measuring module via a high frequency transmission line. The method includes generating, within the electronic module, a signal for compensating in capacitance parasitic effects from the transmission line and the sensor, generating, within the electronic module, a signal for compensating in conductance parasitic effects from the transmission line and the sensor, extracting a signal representative of the capacitance compensation and of a signal representative of the conductance compensation so as to determine an operating point of the sensor and analyzing the operating point so as to check if it is located in a predetermined area.
