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.


NEW: This series is also available with an ATEX type examination.

Application:

  • 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
