Abstract: PURPOSE: Many machine parts look clean but all machine parts are not clean perfectly. The most surface of machine parts are covered various size particles. So an evaluation of participate contaminants is provided to measure the size and number of particulate contaminants in machine parts. CONSTITUTION: A component is washed with a fluid to release particulate contaminant. The particulate containing fluid is passed through a screen (22) having a known number of apertures of identical known size.

From this, a control system (54)determines the number of particles in the fluid having a size greater than the aperture size. This is related to a unit volume by measuring the volume of fluid passing through the screen (22). If the screen blocks before all the fluid is passed through the screen (22), the fluid is pulsed in forward and reverse flow to redistribute the particles on the screen. The fluid is then back washed from the screen to a second screen (28) having a known number of apertures of identical size.

If the second screen (28) blocks, the second screen (28) is pulsed and the fluid back washed to a third screen (32) having a known number of apertures of identical size. The number of particles per unit volume having a size greater than the size of the third screen (38) is then determined. These values are displayed by the control system (54).
