LVDT pressure sensor and process pressure measuring system and method in containment

The invention discloses an LVDT pressure sensor and a process pressure measuring system and method in a containment. The LVDT pressure sensor comprises a shell, a pressure sensing element, a measuring rod and an induction coil, wherein the pressure sensing element, the measuring rod and the induction coil are arranged in the shell; when the pressure sensing element deforms or displaces, the pressure sensing element changes the relative position relation between the measuring rod and the induction coil, so that the inductance in the induction coil changes. The invention aims to provide the LVDT pressure sensor and the process pressure measurement system and method in the containment vessel, wherein the LVDT pressure sensor and the process pressure measurement system and method in the containment vessel are low in arrangement and power supply design requirements, simple in structure and good in measurement performance in an accident. 本发明公开了一种LVDT压力传感器、安全壳内过程压力测量系统及方法，LVDT压力传感器包括壳体和设置于所述壳体内的感压元件、测量杆、感应线圈；当所述感压元件
