Abstract :
The measuring error in high precision electronic balance mainly results from the nonlinear error of weighting sensor. To deal with this problem, a novel adaptive segmenting best-fitting method is proposed in this paper to reduce the nonlinear error in the weighting sensor. A resistance strain type electronic balance manufactured by Shanghai Jing Tian Electronic Instrument Co., Ltd is used as the testing platform. The measuring results show that electronic balance can achieve the accuracy of 1 milligram within the temperature range from -10□ to 40□. And the measuring error is significantly reduced by this approach. Moreover, the improved electronic balance is applied to industrial sorting. And the design of a badminton ball head sorting system with a high sorting accuracy is accomplished and illustrated in this paper.
