Air Differential Pressure Switch 930

The air differential pressure switch 930-series is suitable for low differential pressure switching applications in air-conditioning systems for providing indication of fan status or ´filter dirty`.

The cable gland for air differential pressure switch 930-series using a cap nut offers highly effective strain relief and a considerably better sealing function.

Applications

Air differential pressure switch 930-series used for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.

Possible fields of application for air differential pressure switch 930-series:
· 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
