湿度传感器不确定度评估研究

Study on Uncertainty Evaluation of Humidity Sensor

本文阐述测量不确定度的原理和评定思路及步骤,介绍了不确定度评定的各种方法,为了更好更完善的得到湿度传感器的不确定度,详细分析计算了HMP45D湿度传感器的A类和B类不确定度,以及合成标准不确定度和扩展不确定度,这样就更加完善的评估了自动气象站上湿度传感器的不确定度,确保了观测数据的完整性和可靠性。

The principle of measurement uncertainty and evaluation of ideas and steps are described. Various methods of uncertainty evaluation are introduced. In order to get a better and more complete uncertainty of the humidity sensor, this paper analyzes the calculation of the HMP45D humidity sensor class A and B class uncertainty, and the synthesis standard uncertainty and extended uncertainty. In this way, the uncertainty of the humidity sensor of the automatic weather station is improved, which ensures the integrity and reliability of the observation data.
