压力变送器示值误差不确定度的评定

Pressure transmitter Indication Error Uncertainty Evaluation

对测量结果的不确定度评定,是检测工作重要的组成部分。不确定度是与测量结果相联系的表征测量结果品质的合理地赋予被测量之值的分散性的一个参数或一组参数,需要我们准确地评定,本文就最常用的二线制压力变送器示值误差的测量结果的不确定度如何评定进行了较为实用的分析探讨。

For the measured results of the uncertainty,detection work is an important part.Uncertainty is associated with measurement results of the measurement result of quality characterization reasonably gave the values of measurement of the dispersion of a parameter or a set of parameters,we need to accurately assess,this paper is the most commonly used two wire pressure transmitter and value of the error of the uncertainty of measurement results to assess for a more practical analysis is discussed.
