Kromschroder Pressure Switches For Gas DG..U, DG..H, DG..N, DG..B, DG..I, DG..S
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 is adjustable via 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.
For positive pressure (gas, air), negative pressure (air) and differential pressure (air/air) :
