Compact Transmitter for Moisture in Oil Measurement



EE381 from E+E Elektronik GmbH

The NEW 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 (-40...176°F).

The specifically for that application designed 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 by E+E Elektronik.

Measured variables are water activity aw [0...1], temperature T [°C or °F] and the calculated water content x [ppm].

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 (1450 psi) 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.

Typical applications are monitoring of transformer oil, hydraulic oil, motor oil of ship engines and lubrication oil of bearings.
