Abstract : In this paper , directed by the basis theory of compensation network with sensor , a new kind of compensation network model with optical fiber sensor of measuring oil film thickness has been set up. Based on a factor that takes effect on pressure lubrication oil ,a novel all-fiber compensation network structure with three access-couples is applied. According to the actual application of operating experiment , compared with other conventional network ,this structure of compensation network possesses characteristics as fine-property , simple structures and is easy to achieve. The measuring accuracy of optical fiber sensor of measuring oil film thickness is increased deeply.
