This paper reviews fiber Bragg grating sensing technology with respect to its use in mainstream industrial process applications. A review of the various types of sensors that have been developed for industries such as power generation, water treatment and services, mining, and the oil and gas sector has been performed. A market overview is reported as well as a discussion of some of the factors limiting their penetration into these markets. Furthermore, the author's make recommendations for future work that would potentially provide significant opportunity for the advancement of fiber Bragg grating sensor networks in these mainstream industries.

“…Twenty four strain sensors were divided into three columns, respectively, arranged in the first span bridge bottom 1/4, 1/2, 3/4 points across, each column for a group of eight strain sensors. At the ends of each group, a temperature compensation sensor was installed [7,8]. The wavelength of the sensors in each column was different, connected with each other.…”

Abstract:The theoretical design method of enhanced sensitivity fiber grating (FBG) strain sensors was given, and moreover high qualified strain sensors were developed and fabricated, whose sensing properties were good for practical applications. The strain sensor with cylindrical shell encapsulation contained three tubular structures, due to the uneven surface structure, in the area of the strain concentration, improving the sensitivity. It could achieve the embedment strain measurement and surface measurement and had the advantages of the easy installation. The good agreement was obtained between the measurements and theoretical simulation results. After each calibration test, twenty-four FBG strain sensors and six FBG temperature compensation sensors have been installed on the undersurface of the box girder of Diaoshuiyan bridge in Yongtaiwen highway. Finally, we built up a long-term structure health system for the highway bridge.

“…For measuring magnetic field strength accurately, magnetic force induced strain should be measured effectively with www.intechopen.com processing of temperature compensation. The relative Bragg wavelength shifts in response to axial strain change (  / B ) in a packaged FBG sensor can be described as the following equation (Liu et al, 2000).…”
