Abstract: A pressure transmitter has a pressure sensor, an isolator diaphragm, and a fill tube. Interior passages in the pressure sensor module body are filled with isolator fluid and provide fluid connections. The isolator fluid couples pressure from the first isolator diaphragm assembly to the pressure sensor. A first crimp portion of the fill tube radially narrows into a substantially solid circular cylindrical cross section to form a first primary seal that is resistant to high pressure cycling.

Abstract translation: 压力变送器具有压力传感器，隔离膜和填充管。 压力传感器模块主体中的内部通道充满隔离器流体并提供流体连接。 隔离器流体将来自第一隔离膜组件的压力与压力传感器耦合。 填充管的第一卷曲部分径向变窄为基本上实心的圆形圆形横截面，以形成耐高压循环的第一主密封。
