ABSTRACT:
An apparatus and method for selectively detecting particles above a predetermined size in oil lubrication systems, is disclosed. The oil tangentially enters a cylindrical chamber, whereby rotary motion is imparted to it. A detection cavity is positioned in the outer cylinder at its periphery. Heavier particles which are used by the apparatus to detect failures are transported into the cavity by centrifugal force while lighter particles remain suspended in the oil. A sensor is contained within the cavity to detect the heavier failure particles. A filter is combined with the apparatus for removing the lighter wear particles which would otherwise remain suspended in the oil. In another embodiment a self closing valve enables the filter to be removed from the system without requiring the oil to be drained.
