Compact Moisture in Oil Sensor

對我們的產品有問題？

The robust, accurate and long term stable EE381 moisture in oil sensor is ideal for in-line monitoring of various oils as well as for predictive maintenance of plant and machinery.

The EE381 measures water activity aw and temperature T, and calculates water content x in ppm in transformer, lubrication and hydraulic oil, as well as in diesel fuel.

The measured data is available on two analogue outputs and on the optional LCD display.

The robust metal EE381 enclosure can be rotated for optimal positioning of the display and the status LEDs.

An optional adapter and the free EE-PCS Product Configuration Software facilitate easy configuration and adjustment of the EE381.
