Pressure switch Weishaupt GW 150 A4

The Dungs GW 150 A4 pressure switch is used in gas equipment to control excess pressure and vacuum pressure. This compact device features uninterrupted operation, reliable performance, and high-quality insulation of electrical contacts. Meets the EN 1854 standard.

Key parameters

• System pressure: no higher than 500 mbar.

• Setting within: 30-150 mbar.

• Response interval: 0-3 mbar.

• Controlled environment: gas (family 1-3 neutral), air.

• Operating temperature range: -15…+70 °C.

Features

When the pressure changes relative to the set limit, the relay is triggered, the electrical contact closes/opens and a signal is transmitted to the control device.

A hole with an internal thread of 1/4 inch is used for connection to the pipeline.

The compact device has a plastic case (the base is cast from aluminum), a membrane from NBR. The outer shell is characterized by excellent dust- and moisture-proof properties (IP54).

To change the response limit, a wheel with a scale located in the upper part of the case is used.

The sensor can be mounted in any position (recommended - vertical). With a non-standard orientation, the relay will switch at a pressure below / above the specified response parameters.

Advantages:

• convenient manual parameter setting;

• protected design (IP54);

• stable precise operation;

• wide range adjustment;

• threaded fit.
