The CMS in-line contamination monitor automatically measures and displays particulate contamination, moisture and temperature levels in various hydraulic fluids. It is designed specifically to be mounted directly to systems, where ongoing measurement or analysis is required, and where space and cost are limited.
CMS Water and Temperature Sensor
The water sensor option measures water content using a capacitive RH (relative humidity) sensor. The results is 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.
All CMS units are supplied with software to download automatically new results as they are generated, provided the test is done while being directly controlled by the software. Or alternatively historical results can be downloaded form the CMS’s inbuilt memory. The CMS memory has space for around 4000 log entries, when full, the oldest log entry is overwritten.
- Which test are logged, and when, are determined by the log settings
- Each log entry is time-stamped and contains the CMS serial number, so that it can be identified later.
CMS Alarm Relay Status LED
All CMS versions have a multicolour indicator on the front panel, which is used to indicate the status or alarm state. The alarm thresholds can be set from the supplied software via the serial interfaces.
