Oil moisture measurement in hydraulic power units

Application description


Continuous condition monitoring of oils
Water is generally not wanted in hydraulic liquids and lubricants. High concentrations of water can seriously affect operation or even cause damage. The sensor measures the relative humidity in the 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.
