APPLICATION
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.
