HAZARDOUS AREA INSTALLATIONS
The Dwyer® Series AT-DH3 ATEX/IECEx approved Digihelic® differential pressure controller incorporates a flameproof aluminum enclosure that protects the device for use in hazardous areas commonly found in process or industrial applications.
The DH3 differential pressure controller, contained in the Series AT-DH3, is designed for monitoring pressure or air velocity. This controller reduces inventory and installation time by combining three instruments in one unit with a digital display gage, control relay switches, and a transmitter output. The standard LCD display allows the AT-DH3 to display a local pressure reading while simultaneously sending an analog signal to an instrument panel.
The Series AT-DH3 incorporates a cast aluminum enclosure with texture epoxy coating well-suited for industrial applications. An optional windowed enclosure allows individuals to visually view the local pressure value on the DH3 Digihelic® differential pressure controller while the device is energized.
