Series ISDP Intrinsically Safe Differential Pressure Transmitter

Series 3100D Explosion-proof Differential Pressure Transmitter

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.

NIST CALIBRATION available in Product Configurator.
