摘　　要：在已有的皮带张力非接触测量方案中,音波式皮带张力计由于受背景环境噪声干扰,会造成较大的测量误差。新出现的光电皮带张力计基本解决了这一难题,本文分析了光电式皮带张力计的测量原理,提出了基于转速标准装置的光电式皮带张力计的校准方法,并给出了不确度评定的参考方案。In the existing belt tension non-contact measurement scheme,the sonic belt tension meter is interfered by the background environment noise,which will cause a large measurement error.The newly-appearing photoe-lectric belt tensiometer basically solves this problem.This paper analyzes the measurement principle of the photoe-lectric belt tensiometer,proposes a calibration method for the photoelectric belt tensiometer based on the speed standard device,and gives the uncertainty evaluation Reference program.
