  • Ferrous particle counter
    Patent number: 5708198
    Abstract: A method of and apparatus for determining ferrous particle counts in a fluid within a machine fluid system. In a sequential process, a solid particle count in a fluid above at least one given particle size is determined to determine particle size distribution. Ferrous particles are separated from the fluid and a solid particle count in the fluid above at least one given particle size is again measured to determine the solid contamination level of non-ferrous particles only. The solid particle count is compared with the non-ferrous particle count to determine the ferrous particle count above at least one given particle size to determine particle size distribution in said machine fluid system caused by wear.
