正负压力端口均液体兼容 排气螺口提高测量精度 阀块选件简化安装 830 系列是针对液体或气体压力测量的湿-湿式差压压力传感器。电容式传感器具有快速相应的特点，较传统的充液传感器快20倍！传感器通过信号调理电路输出与压力成正比的高精度的线性信号。单向与双向型静压均可达 17 bar (250 psi)。独有的排放端口消除了管道内的气穴影响。 应用： 能耗管理系统 过程控制系统 液气流量 过滤器监测 液位管理
Liquid Media on Both Ports Bleed Screws for Accurate Results Optional Manifold for Easy Installation
The 830 Series is designed for wet-to-wet differential pressure measurements of liquids or gases. They feature fast-response capacitance sensors that respond approximately 20x faster than conventional fluid-filled transducers! Sensors are coupled to signal conditioned electronic circuitry for highly accurate, linear analog output proportional to pressure. Both unidirectional and bidirectional models are available for line pressures up to 250 psi (17 bar). These units feature bleed ports thatallow for total elimination of air in the line and pressure cavities.
