On the study of the dynamic calibration of temperature sensor
a dynamic calibration system for transient surface is introduced.The dynamic performance of Butt-Welded thermocouple temperature sensor is tested with the system
its time constant is 41.6 ms
dynamic repeatability of the experimental results is 0.72 %
the uncertainty is 0.3 ms.The results show that the dynamic repeatability is good
the precision of measurement is high.Through dynamic calibration
the modified value of dynamic temperature obtained is 300 ℃.The research results have some application values to the research and the use of temperature sensor.
