616WL系列压差变送器

产品名称:  616WL系列压差变送器
产品型号:  616WL系列

 

产品介绍

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.
