ABSTRACT:
A filter press has a support frame; a plurality of face-to-face oriented filter plates movable towards and away from one another and forming a filter plate stack; a closing device connected to the filter plates for exerting thereon a pressure with which the filter plates are urged to one another; a closing pressure regulator coupled to the closing device; a stationarily supported path-sensing signal transmitter connected to the closing device; and a sensor arm connected at least indirectly to one of the filter plates for displacing the sensor arm by, and as a function of the motion of, that filter plate. The sensor arm is coupled to the path-sensing signal transmitter for controlling the closing pressure of the closing device by the signal transmitter as a function of the position of the sensor arm.
