Abstract

To meet the need of the pressure measurement in high temperature oil wells, an extrinsic optical fiber Fabry-Perot(F-P) pressure sensor on the surface of silver coating realized by physical vapor deposition is developed. The F-P cavity sensor fabricated by CO2 laser thermal bonding technique has characteristics of large dynamic gauge ranges, low temperature sensitive, high temperature resistance and high pressure resistance The pressure resolution of 0.006MPa, the temperature sensitivity is less than 0.005MPa/°C, the repeatability of 0.05%F.S over the full scale from 0 to 42 MPa has been achieved.
