Description

High-pressure switch GW...A4/2 HP SGS

All gas-bearing parts are made of stainless steel 1.4541 Pressure monitoring of biogas installations operated with biogases and sewage gases according to DVGW worksheet G 262. All pressure switches have proven suitability for barn atmosphere in accordance with DIN EN 60730-2-9.

High pressure switch GW...A4 HP SGS

The control unit reacts on overpressure, which connects, disconnects or switches a circuit when exceeding or falling below a set nominal value.

Function

The overpressure acts via the metal bellows (GW...A4/2 HP) against the force of the adjusting spring on the micro switch. The pressure switch works without auxiliary power.
