Moisture content sensor

Water in hydraulic and lubrication fluids is one of the main causes of oxidation, additive depletion, loss of dielectric strength in insulating oils, corrosion, and reduced lubricating film thickness.


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 % relative humidity. Making it the perfect solution for gearboxes, thrusters, and other applications where free water is a threat. By combining the MCS with other oil monitoring products like a Condition Monitoring Center and vacuum dehydration unit, we offer you the optimal solution for your water contamination problems.

The compact design and rugged stainless steel housing allow a space-saving installation in the most demanding applications. The MCS measures water activity and oil temperature. The measured values are available on two 4-20mA outputs and one digital output with the MODBUS RTU interface and can be integrated with Condmaster Ruby.
