what is LGW3A4 Dungs
The LGW3A4 Pressure Switch 232716 by LGW is a highly versatile and dependable solution for pressure control, designed to deliver reliable performance across a wide range of applications. With an IP 65 rating, this pressure switch is well-suited for use in demanding environments, offering protection against dust and water ingress.
The LGW3A4 features a pressure range of 0.4 to 3 mbar, making it ideal for precise pressure monitoring in various industrial systems. It is available in two models: the LGW-A1, which comes without a cover and has a fixed pressure setting with an AMP plug for electrical connection, and the LGW-A2, which includes a cover with an adjustable scale and screw terminal connections with PG 11 threading for greater flexibility in installation.
Equipped with a G3 plug and a 3-pole + E connection, the LGW3A4/2 Pressure Switch 232716 ensures reliable and consistent pressure control in a compact, rugged design. Trust LGW for high-quality, efficient pressure management solutions that meet your operational needs.
Main differences from other models in the same series
The key point lies in the adjustment range. The number in the model typically represents the upper limit of its adjustable range:
LGW3A4: The adjustment range is 0.4 to 3 millibars (mbar). It is designed for extremely low pressure applications.
LGW50A4: The adjustment range is 2.5 to 50 mbar. It is suitable for medium and low pressures.
LGW150A4: The adjustment range is 30 to 150 mbar. It is suitable for medium and high pressures.

Typical application scenarios
Fan operation status monitoring (Airflow Proving)
In large ventilation or combustion systems, it is necessary to confirm whether the fan is actually operating and generating airflow, rather than just the motor running idle. LGW 3 A4 can detect the slight positive or negative pressure generated after the fan is started, thereby confirming that the airflow is normal.
Air filter clogging monitoring
As the air filter becomes increasingly clogged with dust, the pressure difference across it gradually increases. The LGW 3 A4 is capable of detecting these subtle changes in pressure difference at the early stages of clogging and signaling for maintenance or replacement.
Combustion chamber negative pressure monitoring
In some large boilers or combustion furnaces, it is necessary to maintain the combustion chamber in a slightly negative pressure state to ensure safety. LGW 3 A4 is capable of precisely monitoring this slight negative pressure to prevent accidents.
