Abstract: To improve the temperature sensors dynamic characteristics the dynamic compensation based on the dynamic calibration results for temperature sensors is reported. The dynamic modeling and measurement errors compensation are described. The model of temperature measurement system is constructed with the system identification and the validity of this model is testified by the cross-validation method. Using inverse filter method the dynamic characteristics of temperature measurement system are compensated: the dynamic error is reduced and the work bandwidth widened evidently. The method is proved to be effective by the experimental results that the transient temperature is measured by a K type butt-welded bare wire thermocouple.
