摘要
以国产智能气压测量仪为研究对象,选取国产DYG4和国外PTB系列气压传感器为实验样本,对国产智能气压测量仪的实验室校准方法展开研究;校准方法对校准所用仪器设备、校准项目、校准数据处理原则展开分析,在校准方法研究基础上设计了DYG4自动化校准系统;校准案例中对样本仪器示值误差、回程误差、测量结果重复性进行了测试,并评定了示值误差测量结果的不确定度,DYG4在各校准点不确定度为0.14 hPa,PTB系列为0.12 hPa;实验室比对结果表明,各校准点归一化偏差绝对值均未超过1,证明校准方法合理。
Taking the domestic intelligent barometer as the research object,the sensors of domestic DYG4 and foreign PTB series barometer are selected as the experimental samples to study the calibration method of the domestic intelligent barometer in laboratory;The instruments and equipment,calibration items and data processing principles are analyzed by the calibration method,and an automatic calibration system for the DYG4 is designed based on the research method;In the calibration case,the indication error,return error and repeatability of measurement results of the sample instrument are tested,and the uncertainty of indication error of measurement results is evaluated.The uncertainty of the DYG4 at each pressure point is 0.14 HPA,and that of the PTB series is 0.12 HPA;The comparison results of laboratory show that,the absolute value of normalized deviation of each pressure point does not exceed 1.0,which proves that the calibration method is reasonable.
