The Dungs LGW 3 A2 pressure switch is a precision electromechanical device designed for gas pressure monitoring in commercial heating systems and industrial burner applications. Operating within a range of 0.5 to 15 mbar, this compact switch features a durable aluminum housing with IP40 protection and incorporates a high-sensitivity SPDT microswitch 1NO+1NC for reliable electrical switching. The unit offers manual differential pressure adjustment via an external screw and maintains stable performance across temperatures from -20°C to 60°C , complying with European safety standards EN 161 and EN 1643 for gas appliances.
Engineered by Dungs for combustion control systems, the LGW 3 A2 model includes 1/8" NPT pressure ports and operates without external power, making it suitable for fail-safe applications. Its corrosion-resistant brass sensing element ensures long-term reliability in gas environments, while the compact design allows flexible installation in control panels. The switch features a fixed 3 mbar minimum switching differential and is particularly effective in small to medium-sized boiler systems, providing accurate pressure monitoring with ATEX-compliant safety for non-hazardous areas. The mechanical design prevents false triggering during pressure fluctuations, ensu

Dungs LGW 50 A2 Pressure Switch is a dual-function device designed for monitoring and controlling both positive pressure** and **differential pressure in gas systems, heating units, ventilation systems, and industrial burners. This model can measure gas pressure up to 50 mbar with high accuracy. A key feature of the LGW 50 A2 is its ability to detect both positive and differential pressure within a single unit, making it an exceptionally flexible choice for combined applications involving gas and air lines. Its design is based on a sensitive diaphragm and a durable housing, allowing it to operate reliably in harsh industrial environments.
This pressure switch is equipped with an **SPDT electrical contact** that sends a control signal when the pressure reaches the setpoint. The switching point can be finely adjusted using a built-in calibration screw, and its operation is completely independent of any power supply, making it ideal for use in safety-critical systems. The compact design of the LGW 50 A2 allows for easy panel or in-line installation, even in confined spaces. Compliant with European safety standards **EN** and **CE**, this model is widely trusted in gas-burning systems and combustion equipment due to its stable performance and long service life.
