ABSTRACT:
A filter centrifuge has a feeler arm which contacts the free surface of the centrifuge contents to signify by the angular displacement of the arm, the thickness of the layer of contents in the filter drum. On the contact surface of the filter arm, at least one sensor is provided which is responsive to a characteristic of the material constructed by the arm for signalling the nature of the material.
