Series 616WL Differential Pressure Transmitter

Low Ranges Down to 0.25" w.c. (60 Pa), NEMA 4X Housing

The SERIES 616WL Differential Pressure Transmitter senses very low pressures of air and non-combustible, compatible gases and sends a standard 4-20 mA output signal. All models, including those featuring the 3 digit LCD digital read-out, are factory calibrated to specific ranges as listed in the chart below.

Positive, negative and differential pressures can be measured within a full span accuracy of ±0.50%. This weatherproof unit is enclosed in a polycarbonate case, designed to meet (IP66/NEMA 4X). Internal digital push button zero and span allow for quick and simple field calibration.

Product Applications

  • Low pressure applications
  • Outdoor HVAC
