| Abstract: | This paper puts forward a new method of making the dynamic property test on the surface temperature sensor by using the high frequency modulated high power CO2 laser as the driving source,and sets up a dynamic property measuring system.A Butt-Welded thermocouple of company OMEGA has been tested on the system by using DIAMONG OMEGA series K-500 type CORHENT CO2 laser,and the experimental results show that the response time of the Butt-Welded thermocouple is 41.6 ms. |
