Most commonly used to monitor hydraulic systems, transmissions and turbines. Often used to determine what other tests should be carried out.
The following services complement normal (spectrometric) oil analysis to provide an even better understanding of equipment operating conditions and performance.
Particle counting indicates the cleanliness of an oil by determining the level solid contaminant particles present. Utilising two extremely accurate methods, fluid flow decay or light blockage, each technique can identity individual particles to over 100 microns in size.Fluid flow decay involves pushing oil through mesh screens under pressure the speed of the fluid indicating its level of contamination.
As the term suggests, light blockage involves passing an intense beam of light through the sample. As particles block the beam they are numbered and sized. Castrol refers to both the ISO 4406 and NAS 1638 standards for reporting these tests, and the results are tabled as the total number of particles in certain size ranges per millilitre of oil.This method of oil analysis is often used in conjunction with Spectrometric analysis.
