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.

A filter centrifuge, comprising: a housing a filter drum rotatable in said housing to centrifuge a suspension in said drum; a feeler arm pivotally mounted in said housing and having means defining a contact surface for contact with the contents of said drum and having means for signalling a degree of filling of said drum in terms of position of said arm; and sensor means at said contact surface for detecting at least one physical characteristic of the contents of said drum contacted by said feeler arm for signalling the nature of said contents, said arm in the region of said contact surface having a knife-edge shape with a narrow front edge turned in a direction opposite the direction of movement of the drum.
