Dwyer DH3 Digihelic® Differential Pressure Controller
The DH3 controller is a perfect tool for pressure, velocity and flow applications. The DH3 ranges from 0.25" w.c. to 100" w.c. and it is also available in bi-directional ranges. Given a 4-20 mA process output the controller uses 2 SPDT control relays with adjustable deadbands. It is simple to access the 5 menus that gives you access to the security level; selection of pressure, velocity or flow operation, engineering units; and K-factor for use with flow sensors. See more info in the pdf datasheet.
