EE364 Moisture in Oil Sensor The compact moisture in oil sensor is designed for reliable online monitoring of the moisture in transformer, engine, lubrication or hydraulic oil as well as in diesel fuel. Besides the accurate measurement of water activity (aw) and temperature (T), the EE364 calculates the absolute water content (x) of the oil in ppm. Outstanding Measurement Performance The sensor employs high end E+E humidity sensing elements which feature outstanding long term stability and high resistance to pollution. Functional Design The small size and robust stainless steel enclosure, together...

Features Measurement Water activity aw  /  Water content x Moisture in oil can be expressed in absolute or relative terms. Water activity aw is the relative measure for moisture in oil. It represents the ratio between the actual amount of dissolved water and the maximum possible amount of dissolved water in the oil at a certain temperature. The aw value indicates the degree of saturation of the oil. aw = 0 indicates completely dry oil, aw = 1 indicates fully saturated oil. The water activity is independent of the type of oil and shows how close to saturation is the oil at any moment in time....

Dimensions Values in mm (inch) Technical DataMeasurandsWater Activity (aw) / Water Content (x) Measuring range 1) The accuracy statement includes the uncertainty of the factory calibration with an coverage factor k=2 (2x standard deviation). The accuracy was calculated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement).
