摘要：
A novel pressure sensor with FBG partly packaged by a metal tube is presented. The thermal-strain cross effect can be avoided. Moreover, its pressure sensitivity is -2.44 X 10(-3)/MPa with the range from 0 to 0.44 MPa, which is 1200 times as that of a bare fiber grating. The linearity of this sensor reaches 0.9986.
