Paper Abstract

An optical fiber pressure sensor based on fiber Bragg grating (FBG) and metal bellows is presented in this paper. Due to the lower spring rate of metal bellows, the sensitivity is improved to 48pm/kPa. The relationship between Bragg wavelength and the applied pressure is derived. Experimental data indicates that there is good linear relation between the Bragg wavelength shift and the applied pressure. This sensor can be utilized in low pressure measurement.
