Kromschroder Pressure Switches for Gas DG
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 between 0.4 and 500 mbar via a hand wheel. It monitors 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.
DG Pressures Switches are for monitoring positive gas- and air-pressure, and for negative and differential air-pressures. The DG version is the European Version and the DG..T is the US version. Both versions offer switching point adjustment via setting dial, are silicon free, and operate with the following media: Gas, air, flue gasses for positive pressure; Air and flue gasses for negative/differential pressure.
