PXT-K系列压力变送器是提供4-20毫安输出的最先进仪器。每个压阻式压力变送器包含一个由压阻式硅片组成的传感器，压阻式硅片安装在焊接在不锈钢外壳上的玻璃金属馈通集管上，并填充硅油。超薄的激光焊接不锈钢隔离膜完成正面。介质压力从不锈钢隔离隔膜通过电池内的油传递到硅测量芯片。这种结构，再加上先进的内部信号调节电路，使仪器坚固耐用，温度误差极小，抗电磁干扰/射频干扰能力一流。外壳和所有浸湿部件均由316L不锈钢制成，符合NACE MR0175的要求。The PXT-K Series pressure transmitters are state-of-the-art instruments providing 4-20 mA output. Each Piezoresistive Pressure Transmitter contains a transducer comprised of a piezoresistive silicon chip mounted on a glass-metal feed-through header welded into a stainless steel housing and filled with silicone oil. The very thin laser-welded stainless steel isolation-diaphragm completes the front side. Media pressure is transferred from the stainless steel isolation-diaphragm via the oil inside the cell to the silicon measuring chip. This construction, combined with the advanced internal signal conditioning circuitry, results in a rugged instrument with extremely small temperature error and class-leading EMI/RFI resistance.The enclosure and all wetted parts are made of 316L stainless steel to comply with NACE MR0175.
PXT-K系列压力变送器可用于压缩机、发动机、过程控制、液位和泵等应用场合。PXT-K Series Pressure Transmitters can be used in applications such as compressors, engines, process control, liquid level and pumps.
