Products Description
The Dungs GW 500 is an adjustable pressure switch manufactured in accordance with EN 1854. It is not a differential pressure switch (like the LGW series), but is designed to monitor the absolute pressure (relative to atmospheric pressure) at a single point. Designed for monitoring and regulating pressure in a variety of industrial applications, including gas and air systems, the very flexible and dependable DUNGS GW 500 Pressure Switch is Its 10 to 500 mbar pressure range makes it especially fit for use in systems like gas burners, heating systems, and air handling equipment where exact pressure management is absolutely vital to guarantee safe and effective operation.
Its working principle is that when the actual pressure rises or falls to the switching point set by the user through the adjustment wheel, the internal mechanical device will drive a micro switch to connect, disconnect or switch a circuit. This action is purely mechanical and does not require an external power supply, so it is very reliable.
Key Product Advantages
Wide pressure range: 10-500 mbar covers most medium- and high-pressure industrial scenarios, reducing system configuration costs.
High durability: Constructed of high-quality materials, it withstands mechanical stress, long-term wear, and corrosive gases (such as gas combustion exhaust).
Easy installation: Simplified wiring and piping connection design, 13mm cable entry for easy cable fixing, and G-thread interface compatible with most industry-standard piping.
Strong environmental adaptability: IP54 protection with a fluid temperature range of -15°C to 70°C, ensuring stable operation in extreme conditions such as low-temperature heating rooms and near high-temperature burners.

FAQ
Q: What's the difference between "maximum pressure 600 mbar (gas)" and "1 bar (1000 mbar)"?
A: 600 mbar: This is the upper safety pressure limit for gas systems (gas is flammable and explosive, and overpressure can easily lead to pipeline leaks or valve damage). It's a "mandatory safety threshold" and must never be exceeded.
1 bar (1000 mbar): This is the maximum structural pressure the device can withstand (for inert media such as air). Air system pressure can approach, but it's not recommended to exceed, 800 mbar for extended periods (to avoid mechanical fatigue).
Q: What are the advantages of a mechanical switching mechanism over an electronic sensor?
A: ① No power supply is required to drive signal conversion, preventing electronic component failures caused by high temperature/humidity.
② Simple structure, 60% lower failure rate than electronic sensors.
③ Fast response speed (≤0.1 second), suitable for scenarios with sudden pressure changes.
Q: What scenarios are mechanical switching mechanisms suitable for?
A: ① High-temperature environments (such as near burners and in boiler rooms);
② High-dust environments (such as cement plant heating systems);
③ Locations with unstable power supply or strong electromagnetic interference (such as outdoor gas pressure regulating stations).
Q: Can IP54 protection be used in "workshops with spray cleaning"? For example, the industrial cleaning area of a food factory.
A: Not recommended. IP54's "splash protection" only protects against "non-directional splashing water" (such as pipe condensation and small amounts of spilled water). Try to prevent splashing water from entering the internal components and damaging the mechanical mechanisms.
