Description
The Dungs GGW 3 A4-U pressure switch, article 248327, is used to monitor the differential pressure of gas and air in combustion units. It complies with the European standard EN 1854. The sensor is used for vacuum.
Main characteristics
Maximum pressure: -500 mbar.
Adjustment in the range: from -0.4 to -3 mbar.
Response interval: 0-0.3 mbar.
Controlled environment: gas, including flue, exhaust gases, air.
Operating temperature: -15°C to +70°C.
Connection: threaded Rp 1/4.
Features and equipment
The model is used if the lower pressure (G 1/8 (-)) is lower than atmospheric. The sensor switch reacts to the differential pressure between the chambers, closing, opening or switching the contacts of the electrical circuit when the pressure exceeds/falls below the set mark.
A scale with markings and a rotary disk are provided to select the response parameters.
The compact relay housing is made of cast aluminum, the transparent cover is made of plastic, the membrane is made of NBC. Gold-plated contacts are used to increase electrical conductivity. Electrical protection class IP 54.
The pressure switch is screwed directly onto the branch pipe with an external thread G 1/4. It should be taken into account that when mounted in a position other than vertical, the response point shifts (see the manufacturer's instructions).
Advantages:
highly sensitive membrane;
flexible adjustment;
reliable operation at temperatures of -15 ... +70 degrees;
resistance to dust and small splashes (IP 54);
compactness, easy installation;
long manufacturer's warranty.
The Dungs GGW 3 A4-U pressure switch is a German-quality device that you can buy on our website. A compact, reliable, trouble-free sensor is the optimal solution for completing industrial boiler equipment.
