Abstract

Fiber Bragg Grating (FBG) sensors sense the change of temperature or strain by detecting the wavelength shifted reflected by the Bragg grating carved on a fiber. Aiming at measuring tension of cables, we did a lot of experiments with FBGs, testing its loading characteristics, temperature response, repeatability, consistency of different sensors, and long term stabilization. When analyzing data, we find that environment temperature has a serious influence to the result. So we use temperature compensation with a temperature sensor. Then we proceeded same experiments with traditional force sensor under the same condition, compared their result and analyze the advantages and disadvantages of the two kinds of sensors in the measurement of cable tension. At last, we made some prospect on FBG using on cable tension measurement.
