读了《中国计量》2010年第5期刊登的《压力变送器输出值误差的不确定度评定》(以下简称《该文》)一文,觉得因不确定度评定方面的不妥,结果导致0.02级标准压力模块用作主标准器及配套设备在检定中引入的扩展不确定度U95小于0.05及压力变送器最大允许误差绝对值的1/4的错误结论。若按该文的理解,0.02级标准 Read the “China Metrology” 2010 the fifth published in the “pressure transmitter output value of the uncertainty of the assessment” (hereinafter referred to as “the article”), I feel due to uncertainty in the assessment of the wrong, the result 0.02 standard pressure module used as the main standard equipment and ancillary equipment introduced in the test of the expansion of uncertainty U95 less than 0.05 and pressure transmitter maximum allowable error of 1/4 of the absolute error conclusion. According to the understanding of the text, 0.02 standard
