Des-Case MCD-S-1 Moisture Content Sensor

Moisture Content Sensor Display

The moisture content sensor (MCS) is suitable for most hydraulic and lubricating fluids. The high accuracy of the measurement and excellent long-term stability make the MCS ideal for online monitoring of moisture in transformer, lubricating and hydraulic fluid, as well as diesel fuel. The MCS is perfectly suitable for long-term usage in moisture levels, higher than 90% RH. Making it the perfect solution for gearboxes, thrusters and other applications where free water is a threat. By combining the MCS with other Des-Case products like a Condition Monitoring Center and Vacuum Dehydration Unit, we offer you the optimal solution for your water contamination problems.
