Abstract: In this paper, a kind of thin film thermocouple is designed for transient temperature measurement, and a new experimental scheme of temperature transducer dynamic calibration is presented. The mathematical model of transducer has been acquired using artificial neural networks identification. By many groups of experimental data, networks are trained to realized accurate dynamic calibration of transducer. It has been shown that the method presented in this paper provides reliable experimental results and new theory for transient temperature measurement.

Key words: transient temperature measurement, artificial neural networks, thin film thermocouple, dynamic calibration
