DG Range
The Kromschroder DG Gas Pressure switch is designed to monitor extremely low pressure differentials and will trigger on and off switching operations if a set switching point is reached; this is adjustable utilising the dial located on the front of the device.
Suitable for use with natural gas, LP, bio-gases and air and provide an accurate, reliable monitoring device for use in both industrial and commercial applications. As well as being able to be used as high and low gas/air proving switches in a combustion supervisory system.
It monitors positive and negative gas pressures on various industrial gas and air appliances such as boiler fan monitoring in firing, ventilation and air conditioning systems.
The TUV tested special design pressure switch is used as defined by the VdTUV 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..U and pursuant to EN 1854.
