DWYER Digihelic AT-DHC atex/iecex approved differential pressure controller

The Series AT-DHC ATEX/IECEx Approved Digihelic® Differential Pressure Controller is a 3-in-1 instrument possessing a digital display gage, control relay switches, and a transmitter with both current and voltage outputs. Combining these 3 features allows the reduction of several instruments with one product, saving inventory, installation time, and cost. The Series AT-DHC ATEX/IECEx Approved Digihelic® differential pressure controller is the ideal instrument for hazardous area pressure, velocity, and volumetric flow applications reading in several commonly used engineering units with optional unidirectional or bidirectional ranges. These units achieve a 1.5% or better accuracy on extremely low ranges, and 0.5% accuracy for ranges at or above 1 in w.c. Calibration can be performed in the field (in safe zone only) making maintaining its accuracy more manageable. Additionally, the Series AT-DHC Digihelic® differential pressure controller includes 2 SPDT control relays with adjustable deadbands. Programming the unit is simple using the built-in menu. With scalable 4-20 mA, selectable voltage process outputs, and selectable Modbus® or BACnet communication, this controller can easily fit into your application. Flameproof enclosures are available in aluminum and can include a glass window for viewing process information and set point status on the digital display.
