- 產(chǎn)品名稱: 616WL系列壓差變送器 產(chǎn)品型號: 616WL系列 產(chǎn)品介紹 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. 技術參數(shù) 介質： Air and non-combustible, compatible gases. 材質：Consult factory. 精度：±0.50% F.S., display accuracy ±0.5%. 穩(wěn)定性：±1% F.S./yr. 溫度范圍：0 to 140°F (-17.8 to 60°C). 溫度補償范圍： 20 to 120°F (-6.67 to 48.9°C). 壓力范圍：See Catalog page. 熱效應：±0.02% F.S./°F (0.036% F.S./°C). 電源： 12-30 VDC (2-wire). 輸出信號： 4 to 20 mA. 調(diào)零： Digital, Push Button Adj. 環(huán)路阻抗： DC; 0-900 ohms maximum. 電流：DC; 38 mA maximum. 電氣連接：Screw-type terminal block. 過程連接： Barbed, dual size to fit 1/8" and 3/16" (3.12 and 4.76 mm) I.D. rubber or vinyl tubing. 封裝：NEMA 4X (IP66). 安裝方向： Vertical, consult factory for other position orientations. 重量： Without LCD 17 oz (482 g); with LCD 18 oz (510 g). 認證：CE.
