Pressure switch Dungs GGW 150 A4/2

The Dungs GGW 150 A4/2 pressure switch has improved signal conductivity and increased tightness of electrical components, which guarantees stable and accurate switching and reliable operation of the gas burner automation. This device is used in systems with a pressure of no more than 500 mbar. Conforms to class "S" of the European standard EN 1854.

Features

• The relay switches on/off/on the electrical circuit when the pressure changes by a specified value and transmits a signal to the gas automation. The switching point is adjusted manually by rotating the disk with numbers. Setting range: 30 - 150 mbar, response - 3 mbar.

• The metal case guarantees unconditional protection of electrical contacts when the device is operating in difficult production conditions. IP 65 standard.

• The relay is made of cast aluminum (base), zinc (cover), polycarbonate (switch), NBC (membrane). Gold-plated contacts improve signal conductivity and more accurate response. The housing has a built-in measuring nipple Ø9 mm.

• The switch operates stably in a wide range of operating temperatures, from -15 ° C to + 70 ° C.

• The relay is mounted in the gas system using a threaded connection, which ensures simple and reliable fixation. The standard installation position is vertical. With a different location, the response point moves within ± 15% of the selected value, which should be taken into account during installation.

Advantages:

• sealed design according to IP 65;

• durable metal housing;

• stable operation in difficult conditions;

• high switching accuracy;

• simple and convenient manual adjustment;

• wide range of parameter adjustment;

• small installation dimensions;

• versatility - suitable for most burners.
