0-2 至 0-10,000 psi 压力量程 (0-690 bar) 电压或电流输出 NEMA 4/IP65 、零满可调 856 系列传感器配备铸铝外壳，专为 NEMA 4/IP65 应用设计。坚固的电容元件设计有效的抵抗各种环境影响，如振动、冲击、温度和 EMI/RFI。17-4 PH 不锈钢传感元件无需与腐蚀性液体隔离。½" 螺纹电缆导管提供电气导线通路，可拆卸盖板便于内部接线端子导线安装。 应用： 过程控制 化工生产 农用灌溉设备 天然气管线 粮食加工 工业压力监测
0-2 to 0-10,000 psi (0 to 700 bar) Pressure Ranges Voltage or Current Output NEMA 4/IP65 with Zero and Span Adjustments
The 856 Series is specifically designed for NEMA4/IP65 service and features a diecast aluminum enclosure. Their robust capacitive design is resistant to environmental effects, such as shock, vibration, temperature and EMI/RFI. A 17-4 PH stainless steel sensing element does not require isolation from corrosive media. A 1/2˝ threaded conduit is provided for electrical termination and a removable cover provides easy access to the internal wiring terminal strip.
