Description

General

The GW…A4 pressure switch is an adjustable pressure switch as per EN 1854 (GW 6000 A4 as per DIN 3398T3) for burners. It is suitable for closing, opening or switching over a current circuit when the actual pressure value deviates from the specified pressure setpoint. The specified pressure setpoint (operating point) is set at a setting wheel using a scale.

Application

Pressure monitoring in burner control systems Suitable for gases of gas families 1,2,3 and other neutral gaseous media, as well as air, flue gases and combustion products. GW 500 A4: Free of non-ferrous metals, suitable for gases up to max. 0.1 % by vol. H2 S, dry.
