Abstract
In this study, the measurement technology and temperature compensation calibration method of piezoelectric vibration signal under high temperature environment are deeply discussed. Through experimental test and theoretical analysis, this paper proposes a reliable method for measuring high temperature piezoelectric vibration signal and temperature compensation calibration, so as to improve the measurement accuracy and stability. We propose a new temperature compensation algorithm that combines linear interpolation and polynomial fitting techniques to calibrate sensor outputs at different temperatures. The experimental results show that the measurement error of the piezoelectric sensor is significantly reduced and its stability is obviously improved under high temperature environment. In addition, we also verified the reliability and repeatability of the technology, proving that it has high practical value in practical applications. This research result is of great significance for improving the technical level of industrial inspection and safety monitoring.
