Series 616W Differential Pressure Transmitter

Brand: Dwyer Instruments, LLC
Does not ship to OH, United States
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.
Features
  • NEMA 4X rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists
  • Easy to read LCD display provides immediate local alerts allowing corrective action to be taken quicker to eliminate the problem from becoming widespread
  • Zero and span controls provides easy calibration checks and shorter installation time to get device running and monitoring
