Description
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 handwheel.
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.
Features
- Monitoring of gas and air pressures (positive, negative, and differential pressures)
- With approved isolating amplifier for Zone 1 and 2 hazardous areas
- Handwheel set to rising pressure/ DG switches with rising and falling pressure
- Rp threads
