Abstract
A method and system for measuring time constant of thermal sensor was put forward.The system heated electrically the thermal sensor firstly, then made it cool in the medium naturally. And the temperature of the sensor was measured and recorded by the system in the progress. The time constant was the time used for change of temperature arriving 63.2% of its maximum. The method is accurate in accuracy , and the system is simple in structure.
