The invention provides a sensor element quality evaluation method based on test data, which is used for reliability screening of a sensor element. The method is based on sensor element test data, usesthe mathematical methods of correlation analysis and principal component analysis to explore information implied in the sensor element test process data, and uses probability and statistical methodsto quantify and interpret analysis results to eliminate risky sensor elements. The invention can effectively compensate for the shortcomings of the traditional method only relying on reliability testsfor screening from the perspective of experimental data analysis, can be well used for reliability screening of the sensor element, and is especially suitable for applications where the reliability of the sensor element is high in the fields of aviation, aerospace and the like.
