Compact transmitter for moisture in oil measurement

05 December 2008

The Series EE381 transmitter from E+E Elektronik enables precise measurement of moisture content in oil in the range 0…1 aw at temperatures from -40...80°C. The monolithic humidity / temperature sensor element provides outstanding accuracy and very good long-term stability. Fast response time and high resistance against chemical contamination are the main features of this sensor element HMC01, developed in thin film technology.

Measured variables are water activity, temperature and the calculated water content. The EE381 can be adjusted for measurement of non-mineral oils by entering the particular oil-specific parameters.
The sensing head is pressure tight up 100 bar and can be mounted either with a G½” ISO or a ½” NPT thread.

The rugged, compact metal housing of Series EE381 is rotatable over the full 360 degrees, allowing positioning for excellent readability of the optional dual-line display and easy accessibility of the robust industrial electrical connector - even in difficult mounting situations.

Both analogue outputs are freely scalable and configurable. It is possible to have the transmitter equipped with switching outputs. Status indicators provide easy on-site diagnostics.
