Differential pressure switch 930 with UL approval adjustable from 20 to 5000 Pascal

Differential pressure switch 930 with UL approval adjustable and cable conduit

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.

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
