Controller for pressure, velocity and flow

The Series DH DigiHelic® Differential Pressure Controller is the ideal instrument for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 0.25 in. w.c. to 100 in. w.c. The DigiHelic® provides a 4-20 mA process output, 2 SPDT relays with adjustable dead bands, and selection of pressure, velocity or flow operation.

The DigiHelic® Differential Pressure Controller delivers simplified programming via a menu key. Users can select from a multitude of options, including: security level; set point or set point and alarm operation; auto or manual alarm reset; English or Metric engineering units; K-factor adjustment for use with various Pitot tubes and flow sensors; and circular or rectangular duct size for volumetric flow operation.

The DigiHelic® offers the flexibility to operate from either 120/220 VAC or 24 VDC. Modbus® Communications is standard with every unit. In addition, units are compact, housed in a 1/8 DIN enclosure.

Dwyer Instruments produces a broad range of measuring and control instruments for pressure, temperature, level, flow, and many other related applications.
