DWYER  差压变送器616W-20B-LCD

可选带液晶显示

-

616W系列微差压变送器能够测量正压，负压和差压，精度为0.25%。它采用聚碳酸酯外壳，NEMA 4X（IP66）的防护，用于监测空气或其它兼容气体，输出4-20mA。

两线制的设计，多种量程范围可以选择，工厂会在出厂前校准。量程和零点可在校准时调整，但它不能大幅度改变量程。可选LCD数显用于现场显示（如果不需要LCD显示，去掉后面的后缀）

Positive, negative and differential pressures can be measured within a full span accuracy of ±0.25 with the SERIES 616W Differential Pressure Transmitter. Units are enclosed in a polycarbonate case, rated NEMA 4X (IP66) and operate by sensing the pressure of air and compatible gases then sending a standard 4-20 mA output signal. Design enables operation in 2-wire current loops. A wide range of models are available factory calibrated to specific ranges. The span and zero controls are for use when checking calibration. They are not intended for re-ranging to a significantly different span. The LCD display allows local indication of pressure.
