Pressure, flow controller
Dwyer Instruments, Inc. has announced the Series DH DigiHelic differential pressure controller. The controller is a suitable instrument for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 5 to 100 in. w.c.0
Housed in a 1/8 DIN enclosure, the unit provides a 4 to 20 mA process output, 2 SPDT relays with adjustable dead bands, and selection of pressure, velocity or flow operation. Programming is 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; imperial or metric units; K-factor adjustment for use with various Pitot tubes and flow sensors; and circular or rectangular duct size for volumetric flow operation.
