616WL-2-LCD 616WL-4/12/14/22/32/25/35-LCD 數字微差壓變送器 Dwyer德威爾

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.

FEATURES/BENEFITS

? 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
