Abstract: The observed values of the embedding pressure sensors aren’t the actual stress values in the medium , for the sensor isn’t coupling with the surrounding medium. In this paper, The structure of pressure sensor is described firstly, then combined with the by using numerical analysis of finite element method , the real load feature and stress distribution of pressure sensor are obtained. Finally, a method to modify observation data is proposed so as to provide a theoretical foundation for applying pressure sensor correctly.

Key words: pressure sensor, finite element method, modification factors, stress monitoring
