International ClassG01N 033/30AbstractA 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.Field of SearchContent or effect of a constituent of a liquid mixtureMetallic particle constituent For measuring solid components (e.g., particles) By separation and subsequent measurement (e.g., by weighing, X-ray or microscope, etc.) By flowing through barrier or restriction and measuring flow effect (e.g., pressure, volume of or rate of flow) PARTICLE SIZE By solid content MAGNETIC With additional separator Fluid material examination Lubricant | |
