  • Description
  • Additional information


Positive, negative and differential pressures can be measured within a full span accuracy of +/- 0.25 with the SERIES 616W Differential Pressure Transmitter. 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 display allows local indication of pressure.


Applications: Dust collection; Outdoor HVAC; Roof-top equipment.


Electrical Connections:

3-wire removable European style terminal block for 16 to 26 AWG.
