Pressure switch Dungs GGW 3 A4 article 248673 – differential gas pressure switch, made in accordance with EU standards for automatic burner control. It is used to turn on/switch/switch off the electrical circuit when the actual pressure value changes. It is built into systems with a pressure of no more than 500 mbar.

Features

• The adjustable relay is manually adjusted in the range from 0.4 to 3 mbar by scrolling the disk with a scale marking. The response range is 0.3 mbar.

• The relay has a robust housing with a cast aluminum base and a transparent plastic cover that does not allow dust and moisture to enter the device (protection class IP 54), which ensures reliable, uninterrupted service.

• The switch is made of polycarbonate, the membrane is made of butadiene-nitrile rubber. The design is designed for operating temperatures from -15 ° C to + 70 ° C.

• When the pressure deviates from the set trigger point, the switch closes the contact, the signal is sent to the control unit.

• The relay has a simple installation method. The recommended orientation is vertical. In another position, the triggering will occur at a higher/lower pressure compared to the set parameters (within ±15%, the exact information is reflected in the specification).

The Dungs GGW 3 A4 pressure switch is manufactured in accordance with EU requirements, certified according to EN 1854, class "S". Suitable for most burner models of popular manufacturers.
