针对电涡流传感器标定常用的随机误差分析法会扩大测量误差的估计范围,限制其工程应用的问题,提出了新型误差分析方法,对多批次测量数据进行误差上下限分析,同时建立了测量批次数的判断准则,这样可以更为精确地获得电涡流传感器的测量精度,并且具有较好的工程运用价值。
Because the random error analysis method for eddy current sensor calibration can expand the range of measurement error estimation and limit its engineering applications,a new error analysis method was used herein to analyze upper and lower limits of multiple batches measurement data. At the same time, a criterion for the measurement times was catched up. This method can obtain the measurement accuracy more precise, and has good engineering application values.
