Differential pressure transmitter | range 0-.25" w.c. | with NEMA 4X housing.

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.

Product Applications

Low pressure applications
Outdoor HVAC
Dust collection
Roof-top equipment

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
High precision accuracy at low pressure ranges provides exceptional accuracy for insuring tight-control and minimizing costly out of specification conditions
