It is a 3-in-1 instrument possessing a digital display gauge, control relay switches, and a transmitter with current output. The Digihelic® controller is the ideal instrument for pressure, velocity and flow applications. The Digihelic® controller allows 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 4-20mA process output. The Series DH provides extreme flexibility in power usage by allowing 120/220VAC and also 24VDC power which is often used in control panels. Typical applications include SCFM duct flow, industrial ovens air flow, filter status, clean room pressurization, fume hood air flow and surgical and medical room pressurization.
