Pressure switch Dungs LGW 150 A2P

The Dungs LGW 150 A2P pressure switch, article 272354, is designed to monitor differential pressure. It is characterized by response accuracy, reliability in operation and versatility of application. A special feature of the device marked "A2P" is the built-in test button for checking the safety function. The relay is suitable for a wide range of furnace units, ventilation and air conditioning systems.

Main operating parameters

• Maximum permissible pressure: 500 mbar.

• Media: air, non-aggressive non-flammable gases.

• Setting within: 30-150 mbar.

• Response: 0-3 mbar.

• Class: S in accordance with EN 1854.

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

Design and operating principle

The device responds to differential pressure. When the pressure increases/decreases compared to the set value, the contact closes and a corresponding signal is transmitted to the control unit.

The switching point is set using a rotary disk and scale.

The housing made of reliable polymer material protects the device from mechanical impacts, dirt and splashes, and is made in accordance with the European standard IP 54. Protection can be increased to IP 65 (separate order). The diaphragm made of nitrile butadiene rubber is highly sensitive.

The relay is connected using threaded holes (internal thread G1/4 and G1/8). The device can be installed in any position. If the orientation deviates from the standard (vertical placement), switching will occur at a pressure higher or lower than the set response limit (approx. ± 0.5 mbar).

Advantages:

• safety function test button;

• reliable design, electrical protection class IP 54;

• wide pressure adjustment range;

• easy parameter setting using a disk and scale;

• threaded connection;

• versatility.
