Humidity measurement in oil
Similar to the humidity in the air, the water content in an 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.
Measuring range, 0 ... 1aw
Accuracy- Standard calibration ± 0.02aw (0 ... 0.9aw) ± 0.03aw (0.9 ... 1aw)
Temp. dependence typ. ± (0.00002 + 0.0002 x aw) x .T [ ° C] .T = T- 20°C
Response time at 20°C 1 t90 typ. 10m in in still oil
Temperature Working range probe - 40 ... 180°C (-40 ... 356°F)
Outputs selectable and scaleable outputs 0 - 5V, 0 - 10V, 4 - 20mA
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.
The sensing probe is designed for inline monitoring and can be placed directly in the oil, at pressures up to 10bar (145psi). In addition to direct mounting of the sensing probe, a ball valve installation provides mounting and removal of the probe without interrupting the process.
Easy Calibration and Adjustment of EE36
The user can easily readjust or calibrate the transmitter by using either a simple procedure with two push buttons on the printed circuit board or the configuration software.
The configuration software is included in the scope of supply and allows an easy and fast configuration of the analogue outputs and of the alarm and control thresholds. Further features of the configuration software are adjustment and calibration of the outputs and service operations such as replacement of the sensing elements or of the entire sensing probe.
