Pressure switches for gas
The gas pressure switch DG monitors extremely low pressuredifferentials and triggers switch-on, switch-off or switch-overoperations if a set switching point is reached. The switchingpoint is adjustable via a hand wheel. It monitors positive andnegative gas pressures on various industrial gas and airappliances, such as boiler fan monitoring and differentialpressure monitoring in firing, ventilation and air-conditioningsystems. Pressure switches with manual reset lock off afterswitching. Pressure switches (DG..T) with UL, FM approval arefitted with a nozzle to limit the flow rate (Vent limiter).
