ATEX/IECEX APPROVED DH3 DIFFERENTIAL PRESSURE CONTROLLER
Digihelic Pressure Control in Flame-Proof ATEX/IECEx Enclosure

Combining these three features allows the reduction of several instruments with one product, saving inventory, installation time and money. The Digihelic® controller is the ideal instrument for hazardous area pressure, velocity and flow applications by allowing for the selection of pressure, velocity or volumetric flow operation in several commonly used engineering units. Two SPDT control relays with adjustable dead bands are provided along with a scalable 4-20 mA process output. In velocity or flow modes, a square root output is provided on the 4-20 mA signal to coincide with the actual flow curve. Flame-proof enclosures are available in aluminum and can include a glass window for viewing process information and set point status on digital display.

FEATURES/BENEFITS :
• 3-in-1 instrument allows the reduction of several instruments with one product, saving inventory, installation time and money
• Flame-proof enclosure with optional glass window and aluminum housing protects the device in hazardous areas while giving local visibility to process pressure and set point status

APPLICATIONS :
• Hazardous area pressure measurement and switching
