Description
Model PSM02 screw-in pressure switches in a diaphragm or piston design open or close a circuit, depending on whether the pressure is falling or rising. With one adjustment screw, respectively, the required switch point and the switch hysteresis can also be easily and conveniently set on-site. Optionally, WIKA offers its customers the factory setting of
the switch point.
Special features
- Adjustable switch hysteresis
- Setting ranges: 0.2 … 2 bar [3 ... 30 psi] to 30 ... 320 bar [450 ... 4,600 psi] and -0.85 ... -0.15 bar [-25 inHg ... -5 inHg]
- Non-repeatability of the switch point: ≤ 2 %
- Switching functions: Normally closed, normally open or change-over contact
- Media: Compressed air, neutral and self-lubricating fluids and neutral gases
