A method for determining a heat transmission state by means of a resistance property of a shape memory alloy element

摘要

A method for detecting a environment heat transmission state, which surrounds a positioned, is positioned that the heated, the resistance of the shape memory alloy element is detected and the time interval is measured, which is necessary in order the positioned on a predetermined level of resistance property to heating. Heat from the environment transmission state, which surrounds the positioned, by reference to a relationship between the time which is needed in order to have the shape memory alloy on the predetermined level of the resistance property to heating, and the environment calculated heat transmission state.
