Moisture sensor keeps watch over oil
quality
The new Lufft moisture sensor is based on a long-term-stable chemically resistant capacitive sensor.
Moisture measurement in lubricating and insulation oils makes an important contribution to long-term maintenance functionality of plant and equipment and the water content of transformer oil has significant influence on its insulation properties Moisture monitoring is therefore of essential importance to daily operations

In the same way as gas moisture, the moisture content of oil can be stated absolutely in parts per million or relatively as the actual water content, AW.
Oil that is completely free of water has an AW value of 0; completely saturated oil has an AW value of 1.
The new Lufft moisture sensor is based on a long-term-stable chemically resistant capacitive sensor.
The measurement values that can be selected are water activity (AW), temperature (T) and the calculated water content in parts per million for mineral transformer oil.
For nonmineral transformer oils, the device can be adapted by inputting the oil specific parameters of the specific oil into the A1-SDI (Serial Digital Interface) indicator.
