DWYER 616W-4M-LCD Weatherproof Differential Pressure Transmitter

DWYER 616W-4M-LCD Weatherproof Differential Pressure Transmitter

Dwyer 616W-4M-LCD Weatherproof Differential Pressure Transmitter (0-0-5 kPa) with LCD 

  • Model: 616W-4M-LCD

Positive,Negative and Differential Pressure can be Measured Within a Full Span Accuracy of ±0.25.Units are Enclosed in a Polycarbonate Case,Rated NEMA 4X (IP66) and operate by sensing the Pressure of Air And Compatible Gases Then Sending a Standard 4-20 mA output signal


  • Design Enables Operation in 2-Wire Current loops
  • A Wide Range Of Models Are Available Factory Calibrated to Specific Ranges
  • The Span And Zero Controls Are For Use When Checking Calibration
  • They Are Not Intended For Re-Ranging To a Significantly Different Span
  • The LCD (As Shown To The Left) allows local indication of pressure
