Abstract

Dynamic characteristics are one of the important properties of temperature sensor; improving the dynamic characteristics of temperature sensor is the fundamental purpose of dynamic calibration. In this paper, the author has established a dynamic characteristics testing system based on an analysis on temperature-sensor calibration method, and proposed a new method for testing the dynamic characteristics of surface temperature sensor by using high-power high-frequency modulation CO₂ laser as driving source. Test on the dynamic characteristics of Butt-Welded thermocouple (manufactured by OMEGA Company) shows that the response time of Butt-Welded thermocouple sensor is 41.6 ms, it is in consistent with the given response time. This proves that the high-power high-frequency modulation CO₂ laser can be used as the heating source in testing the dynamic characteristics of transient surface high-temperature sensors.
