本文较详细地分析了羊毛细度测量系统中的主要测量部件,光电池及A/DC的测量和转换误差。通过定性实验结果的分析,得出选择测量光电池的原则。通过定量实验及结果的分析计算,给出本测量系统中光电池的测量误差限。另外,就测量存在非线性时的A/DC误差进行分析计算。尽管文中结合羊毛细度测量进行分析论述的,但提出的实验及计算方法不仅仅局限于此。它对一般光电池测量及A/DC系统具有普遍意义。
This paper analyzes in more detail the measurement and conversion errors of the main measurement components, photo cells and A / DCs in the wool fineness measurement system. Through the qualitative analysis of the experimental results, the principle of selecting the measurement of photovoltaic cells. Through the quantitative experiment and the result analysis and calculation, the measurement error limit of the photovoltaic cell in this measurement system is given. In addition, the A / DC error in the measurement of non-linearity is analyzed and calculated. Although the text in conjunction with wool fineness measurement analysis discussed, but the proposed experiment and calculation methods are not limited to this. It is of general significance for general photo cell measurement and A / DC systems.
