Description

General

The differential pressure switch GGW… A4 is an adjustable gas-differential pressure switch as per EN 1854 for automatic burner controls. It is suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference value (switching point) is adjusted on a setting wheel provided with a scale. The test nipple is integrated in metal housing as standard.

Application

Differential pressure switch in furnace, ventilation, and air conditioning applications. Differential pressure switch: Suitable for employment with gas family 1, 2, 3, and other, neutral, gaseous media as well as air, smoke and exhaust gases. It does not contain any non-ferrous metals, suitable for gases of up to max. 0.1 vol % H2 S, dry.
