Dwyer
The AT-DH3 series differential pressure controller is ATEX/IECEx approved and incorporates a flameproof aluminum housing that protects the device for use in hazardous areas typically found in process or industrial applications.
In addition, the differential pressure controller is designed to monitor air pressure or velocity, reducing inventory and installation time by combining three instruments in a single unit with a digital display meter, control relay switches and a transmitter output. In turn, the standard LCD display allows the AT-DH3 to display a local pressure reading while simultaneously sending an analog signal to an instrument panel.
Also, the design has an optional window box that allows people to see the local pressure value on the DH3 differential pressure controller while the device is energized.
