Pressure switch Dungs GGW 10 A4-U/2

Pressure switch Dungs GGW 10 A4-U/2 article 248691 is a reliable device with an increased degree of electrical protection, uninterruptible switching system and compact housing. The sensor is designed for error-free monitoring of differentiated gas and air pressure in industrial-scale heating systems. It is used for vacuum. Meets the European standard EN 1854.

Main characteristics of the model

• Maximum pressure in the system: -500 mbar.

• Adjustment in the range: from -1 to -10 mbar.

• Response interval: 0-0.5 mbar.

• Typical environment: gas of 1-3 families, smoke, exhaust, neutral gases, air.

• Permitted operating temperature: -15°C to +70°C.

Connection: thread G1/4 and G1/8 inches.

Design and features

The relay has a reliable design with a high degree of electrical protection (IP 65 standard). The base is aluminum casting, the casing is cast zinc. The sensitive membrane is made of butadiene-nitrile rubber.

Stable operation of the switch and a high level of signal transmission are ensured by the use of gold-plated contacts.

The switching mechanism responds to the differential pressure between the chambers, closing, opening or switching the contacts of the electrical circuit when the pressure exceeds/decreases relative to the response limit.

To simplify the adjustment of the device, the design is equipped with a wheel and a scale.

Mounting is carried out directly on a pipe with an external thread R 1/4. Standard orientation is vertical. Changing the position entails moving the switching point (at a pressure below/above the specified value).

Advantages:

• uninterrupted switching system;

• highly sensitive membrane;

• simple manual adjustment;

• stable operation in difficult conditions;

• metal dust- and moisture-proof housing;

• threaded connection.
