Abstract

PURPOSE: To prevent magnetic powder from remixing into oil by judging the magnetic powder removing capability of an oil filter by detecting electric resistance, etc., that varies with the amount of magnetic powder deposited between the opposite different magnetic poles of a magnet in the oil filter.
CONSTITUTION: To judge the magnetic powder removing capability of the oil filter provided with magnet 3 is filter 2 in casing 1, electric resistance or magnetic permeability varying as magnetic powder is deposited between the opposite different magnetic poles of magnet 3 in filter 2 is detected by detector 7, whose output is referred to. Namely, when the deposit of the magnetic powder on magnet 3 reaches a fixed value for the start of warning, the alarm unit (not shown in the figure) of display unit 8 is put into operation on the basis of the detection result of detector 7. Here, said fixed value should be set within the range where much adsorbed magnetic powder never comes off at a time.
