Pressure switch Dungs LGW 3 A1

The differential pressure switch Dungs LGW 3 A1 is factory-set and complies with the requirements of the European standard EN 1854. It is characterized by precise operation thanks to a special, uninterruptible switching system. The sensor ensures effective monitoring of the differential pressure of gas and air.

Basic data

• Supply pressure (maximum value): 100 mbar.

• Monitored media: air, non-aggressive, non-flammable gases.

• Adjustment in the range: 0.4-3 mbar.

• Response: 0-0.35 mbar.

• Basic setting: 0.8 mbar.

• Ambient temperature: -15…+85 °C.

Operating principle

The differential pressure acts through the membrane on the sensitive microswitch. The relay closes/opens/switches the electrical circuit to the factory-set value when the specified response conditions are reached.

Features:

• Preset response pressure of 0.8 mbar;

• Setting the switching point by turning the screw;

• Compact design;

• Reliable switching system;

• High sensitivity of the diaphragm made of butadiene-nitrile rubber;

• Plastic housing;

• Protection according to IP20 standard;

• Flat electrical plug;

• Hose nipple for pressure supply.
