Designed with adjustable setting
Adjustable pressure switch monitoring overpressure, vacuum or differential pressure of liquid and gaseous – also aggressive – media.
The pressure switch uses a scaled adjustment knob to adjust the trip and reset pressure without using a screwdriver.
Applications of Pressure switch 901 Prescal
- Wastewater technology
- Liquid level measurement
- Pump control
- Medical technology
