Moisture measurement in oil

Water is generally not wanted in hydraulic liquids and lubricants. High concentrations of water can seriously affect operation or even cause damage.
The oil moisture sensor of the LDH series measures the relative moisture in oil in the range of 0...100% by means of a capacitive measuring element. Besides the relative humidity the sensor also outputs the medium temperature as an analogue signal.
