1. A rotary pressure filter comprising:
a filter drum designed to filter a suspension;
a housing which surrounds the filter drum and in which the filter drum is rotatably mounted, a process chamber being formed between the filter drum and the housing;
a separating element arranged between the housing and the filter drum such that said separating element divides the process chamber into a plurality of process portions in a gas-tight manner; and
a sensor arranged on a side of the separating element that faces the housing, wherein the sensor comprises an electrically conductive coil and a metal rod arranged inside the electrically conductive coil, wherein the metal rod is configured to be displaced in the electrically conductive coil based on a change in a distance of the separating element from the sensor;
wherein a resonant circuit is coupled to the electrically conductive coil, the resonant circuit being configured to be detuned when the metal rod is displaced in the electrically conductive coil.
