A novel optic fiber pressure sensor is designed based on the C type spring tube and the optic fiber ring. The theoretical analysis is made of C type spring tube and optic fiber ring, and a theoretical model to be used in determining the pressure and losses caused by the micro bend optic fiber ring is established. The experimental and testing method is used to test the reliability of this theoretical model. The optimal design is made of the installation position, the circle numbers and diameter of the optic fiber ring as well as the spring tubes via theoretical analysis and experimental testing method.
