Abstract

This paper presents a pre-verifiable calibration model, which can accurately characterize the measurement behavior of the flexible wall shear stress thermal sensor in constant current drive mode. In this calibration model, the fitting parameter a can be pre-verified with IRa, which provides a method to verify the accuracy of calibration instruments and data. In repetitive experiments, the average related normalized standard deviation ετ is 1.26%, which indicates that our calibrations are reliable. And the relative deviations η between a and IRa are below 1.15% in all experiments, which indicates that the calibration model can pre-verify the reliability of calibration instruments and data among different sensors and different drive currents.
