The gas pressure switch DG monitors extremely low pressure differentials and triggers switch-on, switch-off or switch-over operations if a set switching point is reached. The switching point can be adjusted using a hand wheel.
It monitors positive and negative gas pressures on various industrial gas and air appliances, such as boiler fan monitoring and differential pressure monitoring in firing, ventilation and air-conditioning systems.
Pressure switches with manual reset lock off after switching. Pressure switches (DG..T) with UL, FM approval are fitted with a nozzle to limit the flow rate (Vent limiter).
