Filter cover, filter device, filter system and method for calculating the remaining service life of a filter element

摘要

The present invention relates to a filter cover (10) for a hydraulic filter and / or for a hydraulic tank with a cover housing (11) which can be connected to a filter housing (12) and at least two control devices (ST1, ST2), a first control device ( ST1) is configured to read out and process data from at least one data memory (DS1, DS2), and a second control device (ST2) is configured to receive sensor signals from at least one sensor (S1) and to process the received sensor signals into measured values and then to send the measured values to the first control device (ST1) for further processing, the first control device (ST1) also being configured to: - on the basis of the measured values and the data read out from the data memory (DS1, DS2) To calculate the filter element (13); - a maintenance prognosis and / or ei based on the remaining service life of the filter element (13) create a recommendation for action for the filter element (13); and to forward the maintenance prognosis and / or recommended action for output to the second control device (ST2) and / or to at least one external controller (EST1), in particular a machine controller.
