摘要
本文分析了热电偶、热电阻等温度传感器动态热传递方程,影响传感器时间常数的因素以及预先测试的喷射装置;综述了时间常数就地测试的LCSR法和噪声分析法以及FFT、功率谱、窗函数、ARMA模型等信号处理技术在动态温度测量中的应用。
In this paper, the heat transfer equation of sensor, the effect factors for time constant of sensor and the jet equipment for a preliminary test are analysed, and the in-situ tests by both LCSR and the noise analysis aredescribed The signal processing technology, such as FFT, power specturm, windor function filter, ARMA model, are applicable to the dynamic temperature measurement.
