Explosion Proof Differential Pressure Switch By Alvi Automation (India) Pvt. Ltd.

We are Manufacturing, Exporting, Distributing and Supplying Explosion Proof Differential Pressure Switches in Jaipur, Rajasthan, India. 930.8x Ex is explosion proof 930_Ex-Proof_Differential Pressure Switch differential 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 a 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.

Some suggested fields of application include:
Monitoring air filters and ventilators
Monitoring industrial cooling-air circuits
Overheating protection for fan heaters
