The Digihelic® II Pressure Controller combines the 2 SPDT control relays, 4-20 mA process output and Modbus® communications with a large, brightly backlit 4 digit LCD display that can easily be seen from long distances. The electrical wiring has also been enhanced in the DHII with its detachable terminal blocks.. Differential pressure controller - is a regulating pipeline fitting designed to automatically maintain a set water pressure difference at impulse pick-up points. Constant pressure difference maintenance is achieved by adjusting the valve passage area. Depending on the reaction to pressure difference changes, controllers are classified as either closing or opening when the pressure difference.
