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 enable the adjustment of trip and reset pressure without the use of a screwdriver.
Ambient temperature from –20° C to 85° C. Temperature of media from 85° C or 130° C depending on material of pressure connection and diaphragm.
Depending on media NBR, Silicone, FKM (Viton®), EPDM. For 901.8x Silicone, others upon request.
