Abstract : The object of the program was to design, develop, and test an in-line metallic debris monitor for recirculating lubricating oil systems. The monitor was based on the removal of metallic debris by the action of centrifugal oil flow and filter screening, deposition of the debris in the annulus of a capacitor, and subsequent measurement of the change of capacitance compared to a reference capacitor of identical dimensions. The unit was found to respond to magnetic and nonmagnetic metallic debris and to changes in the rate of deposition of the debris. The principle of operation of the monitor is sound.
