[0002] At present, as far as the metallurgical industry is concerned, the measurement of the outer surface temperature of various metals is essential in many working processes. In view of the fact that metallurgy cannot be separated from the characteristic of "high temperature", the measurement of the outer surface temperature of various metals , can not be carried out in a simple, direct, convenient and quick way, and there is no instrument or device that meets this requirement; in order to achieve the work goal, the existing technologies usually used include inductive temperature measurement, radiation temperature measurement, compensation Type temperature measurement, conversion type temperature measurement... etc.; the deficiencies, defects and disadvantages of these existing technologies are: complex structure, indirect measurement, inconvenient use, and large measurement error
