Abstract
This paper introduces a new temperature measurement method, which can convert temperature change to phase change in applied AC current, and gives us frequency change as a final output of the measurement. The new method does not require any type of the special thermometers like a capacity thermometer. So the method is applicable to conventional temperature measurement system as an alternative one, and also suitable to the temperature measurement in a rotating cryostat just like a superconducting generator, since the method realizes non-mechanical contact measurement. In this paper, the principle of the new measurement method is studied, and the experimental data of temperature measurement in an actual rotating system is demonstrated, and the results show that the method is applicable for the measurement of rotating system, since the output is quit stable for any rotating speeds (less than 80rps).
