Comparison of fiber in line Fabry-Pérot pressure sensors for harsh environment in aeronautic field

Abstract

In this paper, we propose a comparison of fiber in-line Fabry-Pérot pressure sensors with different structure. The modeling and simulation of pressure sensor with different diaphragm and cavity shape is made. The sensor temperature response up to 900°C is presented. Pressure measurement up to 70bar of four different sensors are demonstrated.
