Beck – Differential pressure Switch 930.80B222234 with adjustable switching pressure.
Adjustable differential pressure switches for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.
Explosion proof differential pressure switch for differential pressure, overpressure and vacuum pressure monitoring of air, clean gases, dry vapour for HVAC applications in building, commercial and industrial area. With its adjustable knob, you can set any switching point within the range. With its intrinsically safe certification, it can be installed in Zone 1 and Zone 2 hazardous area.
Explosion Proof BECK Differential Pressure Switch
For air, clean gases, dry vapour
Model: 930.8x Ex (For Hazardous area Zone 1, Zone 2)
Air differential pressure switch – 930 Ex
930.8x Ex is explosion proof 930_Ex-Proof_Differential Pressure Switchdifferential pressure switch for hazardous area or flameproof classified area installation. This DP switch can be used for monitoring over-pressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.
where x is:
0 = 20-300 Pa with switch differential of 10Pa (0.2 to 3 mbar)
3 = 50-500 Pa with switch differential of 20Pa (0.5 to 5 mbar)
5 = 200 – 1000 Pa with switch differential of 100Pa (2 to 10 mbar)
Differential pressure Switch 930 Ex comes with an adjustable knob which can be rotated, thus it can set at required threshold differential pressure to switch changeover contacts, for pressure control & automation.
