Description
Model PSM03 mechanical pressure switches in a diaphragm or piston variant open or close a circuit, depending on whether the pressure is dropping or rising.
An adjustment knob enables easy, convenient and continuous setting of the required switch point. Optionally, WIKA offers its customers the factory setting of the switch point.
Features- High reproducibility.
- High vibration and shock resistance.
- Setting ranges -0.85 ... -0.15 bar and from 0.2 … 2 bar to 40 … 400 bar.
- Long service life due to high-quality micro switch.
- Precise switch point setting with adjustment knob.
