Abstract

The leakage detector is provided for filter elements of a filter press, including a plurality of filter elements which are clamped together at the edges and which comprise a support wall with a peripherally extending plate frame (1). Between them they form filter chambers with inlets opening therein for the suspension to be filtered and carry at one or both sides pressing membranes which are sealingly connected to the filter element in the edge region and which can be advanced into the filter chamber by a pressure means. The pressure means is supplied or discharged by way of a pressure means bore (3) opening at the edge in the filter element and into which a flow sensor through which the pressure means flows can be inserted. The flow sensor (2) has an axially displaceable damming body (5) which is substantially cylindrical in cross-section and which at its peripheral surface is provided with at least one and preferably two or a multiple thereof of flow passages (6) extending in the axial direction. In addition the damming body (5) has a magnet (7), by way of whose magnetic field the position of the damming body (5) is detected by a magnetic sensor (8) also arranged in the edge region or in the plate frame (1), and is provided as a signal for further processing.
