Pressure switch Dungs GW 2000 A4 HP M

Pressure relay Dungs GW 2000 A4 HP M (article 246665) is a compact, adjustable device for equipping gas burners of most popular manufacturers. The sensor monitors excess gas pressure in combustion units. It has compact dimensions, simple threaded connection, and an uninterruptible switching system.

Main characteristics

• Maximum pressure: 5000 mbar.

• Controlled environment: gas of 1-3 families, neutral, flue gas, air, combustion products.

• Adjustment in the range: 400-2000 mbar.

• Response interval: 0-100 mbar.

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

• Connection: thread Rp 1/4.

Design and features

The relay has a plastic case (base - aluminum casting) with a transparent cover. Electrical components are protected against moisture and dust according to the IP 54 standard.

When the pressure changes relative to the set parameters, the switching mechanism closes the contact and sends a signal to the control device. The device is adjusted manually - a wheel and a scale are provided for this purpose.

Stable, precise operation is ensured by using gold-plated contacts.

The relay is screwed onto a pipe with an external thread R ¼. The standard orientation is vertical. If the sensor is installed in a different position, the operation will occur at a lower/higher pressure relative to the set value (see the installation and operating instructions for the device).

Advantages:

• Uninterrupted service;

• Manual adjustment using a scale and disk;

• Reliable protective design (IP 54);

• Wide range of parameter adjustment;

• Compact dimensions;

• Easy installation on a thread;

• Universal application.
