GTS12型数字探空仪气压传感器测量结果不确定度评定

Evaluation of Measurement Uncertainty of GTS12 Digital Air Sensor

测量不确定度是表明测量结果可信程度的重要参数,是检定系统中最重要的特性指标。通过Model745标准数字气压计与GTS12型数字探空仪气压传感器的数据比对,运用不确定度的评定与表示方法,分析产生误差的影响因素,构建相应的数学模型,并进行有效合成,对GTS12型数字探空仪气压传感器测量不确定度进行评定,为高空气象探测设备探测数据的准确性及可靠性提供依据。

Measurement uncertainty is an important parameter to indicate the reliability of measurement results and the most important characteristic index in the verification system.In this article,through Model745 standard digital barometer and GTS12 type digital radiosonde pressure sensor data,using the method of evaluation and expression of uncertainty analysis error influence factors,the corresponding mathematical model was constructed,and an effective synthesis,type of GTS12 digital radiosonde measurement uncertainty evaluation of pressure sensor,for high altitude meteorological equipment provides the basis for the accuracy and reliability of the detection data.
