Description

Compact Moisture in Oil Sensor The EE381 is designed for the reliable measurement of moisture in transformer, lubrication or hydraulic oil as well as in diesel fuel. It is ideal for the preventive maintenance of equipment and machinery. Besides the accurate measurement of water activity (aw) and temperature (T), the EE381 calculates the absolute water content of the oil (x) in ppm. Measurement Performance The device features the high end E+E humidity sensing elements of the HC series, which stand for long term stability and high resistance to pollution. Display and Outputs The measured data is available on two freely configurable voltage or current outputs, as well as on the LC-display. Functional Design The compact, robust metal enclosure, the swirling front-end and various process connections and sampling options allow for easy and comfortable design-in, mounting and maintenance. Configuration and Adjustment An optional adapter and the free PCS10 Product Configuration Software facilitate easy configuration and adjustment of the EE381.
