Description

ZYMMT are specially designed for the measurement of water content in oil.Transmitter Series EE36 are specially designed for the measurement of water content in oil, it can be portable or online use. They are certified in accordance with the regulations of the "Germanischen Lloyd (GL)" and therefore can be utilized in the maritime field as well. EE36 is ideal 


Humidity measurement in oil
Similar to the humidity in the air, the water content in oil can be described by the absolute value in ppm or by the relative value aw:

PPM (mass of water / mass of oil)

AW (actual water content as fraction of the water content in the saturated oil) aw = 0 corresponds to water-free oil, while aw = 1 describes fully saturated oil

aw measurement with EE36 transmitter series is based on the outstanding long term stability and resistance to pollution of the E+E capacitive sensor elements series HC.


Product Versions
The physical quantities measured are water activity aw and temperature T. With these quantities EE36 calculates the water content (ppm) in mineral transformer oils. Calculation of water content in non-mineral transformer oils and lubrication oils can be accomplished by downloading specific parameters of the oil.

The measured and the calculated values are available on two free scaleable and configurable analogue outputs. In addition, an optional relay output can be used for alarms and process control.
