Custom-made pressure monitoring.

Differential Pressure Switch 930 adjustable from 20 to 5000 Pascal

Adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.

The switching pressure can be adjusted without a pressure gauge using a scaled adjustment knob. Various versions with overlapping adjustment ranges between 0.2 mbar and 50 mbar are available for this purpose. As standard, the pressure switch is equipped with a transparent cover of protection class IP54.

Models:  930.84 / 930.85B / 930.86 / 930.85 / 930.83 / 930.87B

Ranges:  30 – 400 PA / 100-1000 PA / 500-2500 PA / 200-1000 PA / 50-500 PA / 1000-5000 PA

Applications:

Monitoring air filters and ventilators • Monitoring industrial cooling-air circuits • Overheating protection for fan heaters • Monitoring flows in ventilation ducts • Controlling air and fire-protection flaps • Frost protection for heat exchangers.
