English The GW...A4 HP pressure switch is an adjustable pressure switch in high pressure design according to EN 1854 (GW 6000 A4 according to DIN 3398T3) for combustion systems. It is suitable for switching a circuit on, off or over when the actual pressure value changes in relation to the set setpoint. The setpoint (switching point) is set using a dial with scale.
Application
The differential pressure switch is suitable for gases of gas families 1, 2, 3 and other neutral gaseous media, as well as air, flue and exhaust gases. All gas-carrying parts are made of stainless steel 1.4541 and are therefore suitable for applications with operating pressures greater than 600 mbar.
