“…A pressure sensor reported by Hsu et al [73] has a sensitivity of 28 pm/Mpa and is effectively temperature insensitive. They use a strained FBG and mechanical system that reduces the strain on the FBG as the temperature increases causing the Bragg wavelength to shift in the opposite direction.…”

Abstract. An optical fiber corrosion sensor (OFCS) based on iron-carbon (Fe-C) film was researched. OFCS was formed by electroplating a Fe-C film on fiber Bragg grating (FBG) metalized with silver film by magnetron sputtering. There was a more than 430-pm change of FBG wavelength when Fe-C film was seriously corroded. Compared to electrochemical method, the optical fiber sensor shows dominance in long-lasting monitoring of corrosion. The electric signal was broken off after the 20-h corrosion of Fe-C film, while the optical fiber sensor's monitoring lasted more than 40 days.

“…By using two FBGs and analyzing the difference in the wavelength shift, the temperature sensitivity is effectively eliminated. Furthermore, other groups proposed some feasibility techniques such as writing two FBGs in different diameter fibers, using a reference FBG, and combining FBG with Fabry-Perot cavity [15][16][17]. In this paper, a temperature compensation FBG pressure sensor based on the elastic diaphragm is reported.…”

Pressure sensors are the essential equipments in the field of pressure measurement. In this work, we propose a temperature compensation fiber Bragg grating (FBG) pressure sensor based on the plane diaphragm. The plane diaphragm and pressure sensitivity FBG (PS FBG) are used as the pressure sensitive components, and the temperature compensation FBG (TC FBG) is used to improve the temperature cross-sensitivity. Mechanical deformation model and deformation characteristics simulation analysis of the diaphragm are presented. The measurement principle and theoretical analysis of the mathematical relationship between the FBG central wavelength shift and pressure of the sensor are introduced. The sensitivity and measure range can be adjusted by utilizing the different materials and sizes of the diaphragm to accommodate different measure environments. The performance experiments are carried out, and the results indicate that the pressure sensitivity of the sensor is 35.7 pm/MPa in a range from 0 MPa to 50 MPa and has good linearity with a linear fitting correlation coefficient of 99.95%. In addition, the sensor has the advantages of low frequency chirp and high stability, which can be used to measure pressure in mining engineering, civil engineering, or other complex environment.
