Dwyer DH Series Offers

Features

  • The ideal instrument for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 0.25 to 100 in. w.c
  • 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 4-20 mA process output
  • In velocity of flow modes, a square root output is provided on the 4-20 mA signal to coincide with the actual flow curve
  • Provides extreme flexibility in power usage by allowing 120/220 VAC and also 24 VDC power which is often used in control panels
  • Programming is easy using the menu key to access 5 simplified menus which 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 readings; digital damping for smoothing erratic process applications; scaling the 4-20 mA process output to fit your application"s range; Modbus communications; and field calibration
Applications
  • SCFM Flow in Ducts
  • Air Flow for Industrial Ovens
  • Filter Status
  • Clean Room Pressure
  • Fume Hood Air Flow
  • Medical Room Pressures
  • Static Pressures in Ducts or Buildings
  • Damper Control
  • Fan Control
