The gas pressure switch Dungs GW 10 A6 art. 228724

Description:
Adjustable compact pressure switch ‘Dungs’ GW 10 A6 to control the excess
pressure of gas/air.
Serves for switching on, switching off or switching an electric circuit if you change the actual value of the pressure set.
Set point pressure (switching point) is installed with the scroll-wheel with scale. In metal case the product is also built-in measuring and fitting.
Application:
Is used to control the pressure in the combustion units, ventilation installations and installations for
air conditioning. Can be used for gases of families 1, 2, 3 and other neutral gaseous media.
The use of this relay is especially true for chain building trouble-free off gas boiler when the pressure drop in the feed to the boiler gas line.
Operating principle:
The pressure switch works on a simple principle in the range of gauge pressure. When raising or lowering the pressure of the gas at the boundary of the admissible evidence, relay disables or enables the electrical supply circuit of the boiler.
For example, in case of emergency, in the absence of the owner of the equipment or staff, this option enables offline run the boiler without the forced inclusion.
For relay operation is not required auxiliary energy.
The inclusion of the GW 10 A6 is characterized by short response time when a deviation of the pressure values.
