Equipment for monitoring the state of hydraulic, lubricating or cooling liquids

Abstract

Abstract In an equipment for monitoring the state of hydraulic, lubricating or cooling liquids, which are carried by a pump and at least one filter, in which equipment pressure sensors 12 are arranged in a liquid line and are connected to a signalling equipment for indicating the change in the pressure drop across the filter, the measured values from a pressure sensor or from the pressure sensors 12 are fed to an evaluation circuit. In addition, the evaluation circuit comprises an averaging unit 14 for forming pressure-difference averages in prescribed time intervals, and the successive pressure- different averages are fed to a shift register 1, 15 to be stored. <IMAGE>
