Compact Transmitter for Moisture in Oil Measurement

 

The NEW Series EE381 transmitter from E+E Elektronik enables precise measurement of moisture content in oil in the range 01 aw at temperatures from -40...80C (-40176F).

 

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 [01], 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 G ISO or a 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.
