This paper introduces a novel design of "bridge style" fiber-optic weigh-in-motion (WIM) sensor using fiber Bragg grating (FBG) technology. Compared with other designs of fiber-optic WIM sensors, the bridge-style design is reliable, sensitive and can bear more loads. With these advantages, the bridge-style WIM sensor is specifically suitable for heavy vehicle dynamic weighing, especially for military vehicles, cargos and equipments. Experiment is conducted and the results show good repeatability and sensitivity under large loads. The minimum achieved resolvable weight is 7.1 kilograms. Finally, WIM sensor on-site installation method is suggested.
