WIKA PSM02 Series Pressure Switch, 20bar Min, 250bar Max, SPDT Output, Relative Reading

The WIKA PSM02 screw-in pressure switches in a diaphragm or piston variant open or close a circuit, depending on whether the pressure is dropping or rising. Two adjustment screws enable easy and convenient on-site setting of the required switch point and hysteresis. The model PSM02 mechanical pressure switches are employed wherever compressed air, neutral and self-lubricating fluids or neutral gases are used and a precisely set hysteresis is needed.
