Pressure switch Dongs LGW 50 A4

The Dungs LGW 50 A4 pressure switch is a heavy-duty electromechanical device designed for precise gas pressure monitoring in industrial combustion and process control applications. Operating within an extended pressure range of 10 to 500 mbar, this robust switch features a die-cast aluminum housing with IP54 protection, making it suitable for harsh industrial environments. It incorporates a high-sensitivity microswitch with SPDT contacts 1NO+1NC and offers adjustable switching differential via an external calibration mechanism. The device maintains reliable performance across a wide temperature spectrum from -20°C to 80°C and complies with stringent European standards including EN 161, EN 1643 , and PED 2014/68/EU for gas safety applications.

Engineered by Dungs for demanding industrial use, the LGW 50 A4 model features 1/4" NPT female pressure connections and a manual reset function for fail-safe operation. Its corrosion-resistant brass sensing element and reinforced diaphragm ensure long-term durability in continuous operation. The switch is particularly suitable for large burner systems, industrial boilers, and gas distribution networks, with ATEX certification II 2G Ex h IIC T4 for use in potentially explosive atmospheres. The units precision spring mechanism provides consistent switching accuracy even under pressure fluctuations, while its compact design allows for flexible mounting options in control panels or equipment racks.
