Oil Contamination Monitoring sensor
The CMS in-line contamination monitor (particle counter) automatically measures and displays particulate contamination, moisture, and temperature levels in various hydraulic fluids. Atex classified version available - CE II 3 G Ex nR IIB T6 X
It is designed specifically to be mounted directly to oil lubrication and hydraulic systems, where ongoing measurement or analysis is required, and where space and cost are limited.
Features
The water and temperature sensor option measures water content using a capacitive RH (relative humidity) sensor. The results are expressed as percentage saturation. 100% RH corresponds to the point at which free water exists in the fluid, i.e., the fluid is no longer able to hold the water in a dissolved solution.
Measuring results will be stored in Condmaster Ruby and presented in trend graphs with alarm limits.
