217-094A

The Dungs GMH-A4-4-8 gas pressure switch (models 217-094A and 217-328A) is a reliable and efficient solution for monitoring and controlling gas pressure in various applications. This switch is designed to operate within a working pressure range of 4 to 8 bar and a temperature range of -10 to 60 degrees Celsius.

The 217-094A and 217-328A models are interchangeable, with the primary difference being the wiring configuration: the 217-094A comes with a wiring harness for a 200 WC (Water Column) connection, while the 217-328A is wired directly to a 200 WC pressure gauge. This makes the 217-328A model suitable for installations where a separate pressure gauge is already in place.

The gas pressure switch features a robust and corrosion-resistant construction, with a die-cast zinc housing and a silicone gasket to ensure a tight seal. The switch is also supplied with a 1.6 mm (AWG 10) wiring harness, which is long enough to accommodate typical installation requirements.

The switch operates on a simple principle when the gas pressure in the system reaches the set point, the diaphragm inside the switch actuates, which in turn activates the contactor. This contactor then opens or closes the electrical circuit as required, allowing for the control of downstream devices or processes.

The Dungs GMH-A4-4-8 gas pressure switch is an essential component for ensuring the safe and efficient operation of gas-powered systems. Its high-quality components, rugged design, and ease of installation make it an excellent choice for a wide range of applications, including industrial processes, heating systems, and compressed air systems.

To install the switch, simply connect the wiring harness to the appropriate power and control terminals, and then attach the switch to the system using the provided mounting hardware. The switch can then be calibrated to the desired working pressure using the adjustment screw located on the top of the switch housing.

Overall, the Dungs 217-094A and 217-328A gas pressure switches offer a versatile, reliable, and easy-to-install solution for monitoring and controlling gas pressure in a variety of applications. Their rugged construction, simple operation, and wide operating range make them an indispensable tool for maintaining the safety and efficiency of gas-powered systems.
