DUNGS LGW50A4

Dungs LGW 50 A4 Differential Pressure Switch Description The Dungs LGW 50 A4 is an adjustable differential pressure switch designed for high-demand industrial applications. It is suitable for switching a circuit on, off, or over on changes in the actual pressure value relative to the setpoint. This device is widely used in gas-fired systems, ventilation, and air-conditioning technology to monitor air and gas pressures safely and reliably. Specifications Manufacturer: Dungs Type: LGW 50 A4 Part Number: 51100368 Adjusting Range: 2.5 to 50 mbar (0.25 to 5 kPa) Maximum Operating Pressure: 500 mbar Media: Air, flue gas, and other non-aggressive gases Electrical Connection: Screw terminals Switching Capacity: 10 A at 250 V AC Protection Rating: IP 54 Label Info Model: LGW 50 A4 ID.No.: CE-0085AQ0673 Pmax: 500 mbar Gas / 500 mbar Luft (Air) Application Ideal for monitoring differential pressure in firing, ventilation, and air-conditioning systems. It can be used as a pressure, vacuum, or differential pressure switch for air and non-aggressive gases, but not for combustible gases according to DVGW G 260. Country of Origin Made in Germany. CO2 Impact By purchasing this pre-owned component, you help avoid the emission of approximately 16.0 kg of CO2 associated with the production of a new one. This is comparable to the emissions from driving a standard car for 80 kilometers. Availability This item is in stock and ready for immediate dispatch.

FAQ What is the difference between the LGW…A4 and LGW…A2 series?The LGW…A4 series, like this model, features a high-quality die-cast aluminum housing for maximum durability. The LGW…A2 series uses a plastic housing. Both offer excellent performance, but the A4 is preferred for more demanding industrial environments. Can this pressure switch be used for liquids?No, the Dungs LGW 50 A4 is specifically designed for use with dry, non-aggressive gases. Using it with liquids will damage the internal diaphragm and lead to component failure. How do I correctly set the switching point on the LGW 50 A4?The switching point is adjusted using the hand wheel on top of the unit, which has a printed scale in mbar. For high-precision applications, it is recommended to use a calibrated manometer to verify the exact pressure at which the switch actuates. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
