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.
The TÜV-tested special-design pressure switch is used as defined by VdTÜV Code of Practice “Druck 100/1” (Pressure 100/1) in firing installations for steam and hot-water generators in accordance with TRD 604, Para. 3.6.4, as well as class “S” for DG..B, DG..U and DG..I pursuant to EN 1854.
