Dwyer DH-3 Differential Pressure Controller

• Allows the reduction of several instruments with one product
• Save inventory, installation time, and money

The gauge’s keypad allow you to access 5 simplified menus that provide access to: security level; selection of pressure, velocity or flow operation; selection of engineering units; K-factor for use with flow sensors; rectangular or circular duct for inputting area in flow applications; set point control or set point and alarm operation; alarm operation as a high, low or high/low alarm; automatic or manual alarm reset; alarm delay; view peak and valley process reading; digital damping for smoothing erratic process applications; scaling the 4-20 mA process output to fit your applications range and field calibration.
