Overview
DG Pressures Switches are for monitoring positive gas- and air-pressure, and for negative and differential air-pressures. The DG version is the European Version and the DG..T is the US version.
Both versions offer switching point adjustment via setting dial, are silicon free, and operate with the following media: Gas, air, flue gasses for positive pressure; Air and flue gasses for negative/differential pressure. For available accessories, see technical documentation.
