Paper Abstract

A number of embedded sensor protection system (ESPS) and surface-mountable sensor protection system (SSPS) for fibre optic sensor (FOS) have been developed in this paper. Fibre Bragg Grating (FBG) and Extrinsic Fabry-Perot interferometric (EFPI) sensors protected by the designed protections system have been used to monitor the cure progress and structural health status of concrete cylinders. Results indicate that the sensor protection systems for the FOS perform adequately and effectively in concrete environment. The protected fibre optic sensors are suitable achieve the structural health monitoring in practical. It is also revealed that there is excellent correlation between the results obtained from the protected FOS and reference electrical resistance strain gauges.
