DatasheetEE360 High-End Moisture in Oil Sensor

EE360 High-End Moisture in Oil Sensor EE360 is dedicated for reliable monitoring of lubrication, hydraulic and insulation oils as well as diesel fuel. In addition to highly accurate measurement of water activity (aw) and temperature (T), EE360 calculates the absolute water content (x) in ppm. Measurement Performance The EE360 employs high-end E+E humidity sensing elements manufactured in state-of-the-art thin film technology, which are the prerequisite for outstanding measurement accuracy. Process Connection The sensing probe can be employed up to 180 °C (356 °F), 20 bar (290 psi) and is available...

Features Water activity aw / Water content x The 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. Independently of the oil type, the water activity shows how close to saturation is the oil at any moment in time. ▪ aw = 0 indicates completely dry oil ▪ aw = 1 indicates fully saturated oil EE360 measures directly the water activity. Water content x is an absolute...
