Digihelic® Series DH Differential Pressure Controller provides the functions of 3 different units. This controller can be used as a digital display gauge, as a control relay switch, and finally, transmitter with current output. This cost effective and space saving unit is excellent for pressure, speed and and air flow measurement, and offers up to 0.5% accuracy on ranges from 0.25 to 100 in. w.c. The unit accommodates the selection of pressure, velocity, or volumetric flow. It is also equipped with two SPDT control relays that provide adjustable dead bands with a scalable 4-20 mA process output. When used in velocity flow mode, the square root output is transmitted on the 4-20 mA signal to correspond with actual flow. The unit has flexible power use, and allows 120/220 vac and 24 VDC power.
