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. 技术参数 介质： Air and non-combustible, compatible gases. 材质：Consult factory. 精度：±0.50% F.S., display accuracy ±0.5%. 稳定性：±1% F.S./yr. 温度范围：0 to 140°F (-17.8 to 60°C). 温度补偿范围： 20 to 120°F (-6.67 to 48.9°C). 压力范围：See Catalog page. 热效应：±0.02% F.S./°F (0.036% F.S./°C). 电源： 12-30 VDC (2-wire). 输出信号： 4 to 20 mA. 调零： Digital, Push Button Adj. 环路阻抗： DC; 0-900 ohms maximum. 电流：DC; 38 mA maximum. 电气连接：Screw-type terminal block. 过程连接： Barbed, dual size to fit 1/8¨ and 3/16¨ (3.12 and 4.76 mm) I.D. rubber or vinyl tubing. 封装：NEMA 4X (IP66). 安装方向： Vertical, consult factory for other position orientations. 重量： Without LCD 17 oz (482 g); with LCD 18 oz (510 g). 认证：CE.
