Paper Abstract

A fiber-optic extrinsic Fabry-Perot interferometer (EFPI) and fiber Bragg grating (FBG) based pressure sensor system is designed. Using polyimide coated optical fiber, this sensor works in harsh environment of high temperature and high pressure such as oilfield application with the advantages of high sensitivity, quick response and good reliability. Experiments show the sensor system has a pressure accuracy of 0.05MPa over a range of 0.1MPa to 60MPa at room temperature and in the mixed environment of high temperature and high pressure, the pressure accuracy gets to 0.07MPa under the experimental condition.
