Fiber Bragg grating temperature sensor (S300)
Conventional fiber Bragg grating temperature sensors measure surface or internal temperatures of different structures and can be used for tunnel fire protection, switchgear and embedded temperature measurement. High-temperature fiber Bragg grating sensors use regenerated Bragg gratings (RBGs) as sensing elements and measure temperatures from room temperature to 800℃. Regenerated Bragg gratings are obtained by annealing conventional UV-written type Ⅰ fiber Bragg gratings. Their reflectance is stable, and reflected wavelength has a good linear relationship with measured temperature. High-sensitivity fiber Bragg grating temperature sensors measure surface or internal temperatures of different structures, including tunnel fire protection, switchgear and embedded measurement applications. Installation options include surface mounting and embedding. They are widely used for precise temperature measurement in large structures and buildings, such as bridges, dams, offshore oil platforms, and oil and gas pipelines, and in large facilities or equipment in the power, fire-protection and mining sectors. Sensors with corresponding sensitivities can be supplied according to the material's coefficient of thermal expansion.
