Description
The E+E EE381 moisture transmitter is specifically designed for measuring water content in oil. The EE381 is ideal for online monitoring of moisture in lubrication or insulation oil, which is very important for the long-term performance and preventive maintenance of plant and machinery.
The EE381 transmitter has two freely selectable and scaleable outputs for water activity, water content or temperature. The status for early warning and main alarm is indicated by LED’s. Adjustment of the aw/T/ppm set point and hysteresis can be achieved with the optional configuration software.
Typical applications for the EE381 include:
Monitoring of transformer oil
Monitoring of hydraulic oil
Monitoring of ship engines
