Abstract

Abstract: To satisfying the requirements of accurate measurement displacement in the complex environment of high temperature and high pressure, a displacement sensor with high accuracy and low shift is designed. Compared with the traditional LVDT, new structure, new technology, new materials and 7JHB0187 are used in the process of sensor development to adapt high temperature and high pressure environment. The sensor parameters meet the application requirements. Also, the applications of the sensor is expanded.

Key words: Linear Variable Differential Transformer(LVDT), Displacement senor, High temperature, High pressure, Simulation analysis
