EE381 is a compact and rugged moisture in oil transmitter suitable for in-line oil monitoring. High accuracy and long-term stability make it ideal for preventive maintenance of plants and machinery.
The device accurately measures water activity (aw) and temperature (T), and precisely calculates water conent (ppm). It is available with either two analogue analogue outputs or two alarm outputs. LEDs indicate alarm and operation status.
Values are displayed on the optional LCD display. The enclosure of EE381 can be freely positioned (360° rotation) to provide good readability of the display/LEDs in all mounting conditions.
With an optional confugration kit it is possible to adjust the EE381 and configure the analogue outputs.

Oil monitoring for wind turbines
The warranty period of standard gear units for wind energy is usually 2 to 3 years. After the expiry of the warranty period, maintenance teams are responsible for the smooth running of the turbine for the remainder of its service life - which can be up to 20 years
