| Abstract: | A novel fiber Bragg grating pressure sensor used in large weight systems based on a couple of chirped fiber Bragg gratings(CFBG) is developed.The linearity and the repeated error can attain 0.999 93 and 0.09%FS from 0 to 90 kN. In the meantime,the sensor,which don't need expensive wavelength demodulation equipments,is cheaper and has significant applications. |
