ABSTRACT:
Abrasion testing, and hence particle content of fluids including liquids and gases is carried out by abrading a thin film 25 of an electrical conductor with the fluid, and measuring the resulting change in electrical resistance of the film.
The method can be used to monitor metal particles in oil, and hence the state of wear of oil-lubricated metal parts, and the level of particulate pollution in the atmosphere.
