Pressure switch Dungs LGW 3 A2 M

The Dungs LGW 3 A2 M pressure switch is used as a changeover device when the pressure drops or increases. It controls the differential pressure in combustion units with a maximum pressure of no more than 500 mbar. It can be used to equip air conditioning and ventilation systems.

Main parameters

• Maximum permissible pressure: 500 mbar.

• Media: air, non-aggressive gases (except technical flammable gases).

• Setting range: 0.4-3 mbar.

• Response: 0-0.3 mbar.

• Class: S in accordance with EN 1854.

• Operating temperature: -15°C to +70°C.

Design and operating principle

The changeover device reacts to differential pressure. The device switches on/off/changes contacts when the actual pressure changes. The switching point is selected using a rotary disk with a marked scale.

The design is equipped with a highly sensitive membrane made of NBC. The body is made of polycarbonate, has compact dimensions.

The insulation of electrical components meets the IP 54 standard. At the customer's request, IP 65 design is possible.

With the standard mounting position, the relay operates in accordance with the settings. In case of a change in the installation orientation, switching will occur at a pressure higher/lower than the set one by ± 0.5 mbar (approximately).

Advantages:

• sensitive membrane;

• easy installation;

• convenient parameter setting;

• IP 54 protection of electrical contacts;

• wide range of applications;

• compact body.
