Filter cap, filter device, filter system and method for calculating the residual life of a filter element

摘要

filter cap (10) for a hydraulic filter and/or for a hydraulic tank with a lid housing (11),connecting to a filter housing (12) and at least two control devices (ST1, ST2),where a first control device (ST1) is configured to read and process data from at least one memory (DS1, DS2) and a second control device (ST2) is configured to receive sensor signals from at least one sensor (S1), Process the received sensor signals to measurement values an d then send the measured values for further processing to the first control (ST1) and configure the first control (ST1) to do so:Calculate the remaining life of a filter element (13) on the basis of the measurement values and data read from the data storage (DS1, DS2);-to draw up a maintenance forecast and/or action recommendation for the filter element (13) based on the remaining service life of the filter element (13); andforward the maintenance forecast and/or action recommendation for the issue to the second control (ST2) and/or at least to an external control (EST1), in particular a machine control.
