    摘要: The invention relates to a method for real-time tracking of the operational status of a capacitive sensor mountable onto a rotatable machine and connected to an electronic measurement module via a high-frequency transmission line. Said method includes the steps of: generating, within the electronic module, a signal of conductance compensation for interference from the transmission line and the sensor; generating, within the electronic module, a signal of capacitance compensation for the transmission line and the sensor; sampling a signal representing the capacitance compensation and a signal representing the conductance compensation such as to determine an operation point of the sensor; and analyzing the operation point so as to verify if it is located in a predetermined area.
