| Abstract: | Aimed at the problems on the non-linearity and hysteresis of pressure sensor used in bearing load-shear test machine of bridge which the non-linearity of capacitive pressure sensor signal and the hysteresis problem was analyzed. Using the least square method to correct the non-linearity of sensor output signal and using function correction method for hysteresis compensation. The results show that the method can correct the non-linearity and hysteresis. |
