| Abstract: | The basic principle of eddy current sensor is introduced, the primary reason of temperature drift is analyzed, and a sort of new method of temperature drift compensation is brought forward. It completed composite compensation of temperature drift, closed system composed by minus feedback. The precision of composite compensation is showed to be 0.41% by experiment result, being superior to that of common method in evidence. |
