Beck-930 Series Differential pressure switch

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.
We have three varian such as:
  • Differential pressure switch 930 adjustable
  • Differential pressure switch 930 EX adjustable
  • Differential pressure switch 930 with UL approval adjustable
*All varians is adjustable from 20 to 5000 pascal.930-8-Beck-Differetntial-pressure-switch

Applications

Adjustable differential pressure switch for monitor ing overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.
Possible fields of application include:
  • 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

Version

With this pressure switch the switching pressure can be adjusted without a pressure gauge using a scaled adjustment knob.
