This paper designs and analyzes the structure of coils for a levitation gap sensor, which can reduce the output fluctuation when testing gaps between senor and groove surfaces. It analyzes magnetic induction between the coils and the tested conductor. If the values of magnetic induction at a certain gap are approximated constant, the output fluctuation will be lower. Based on the idea, the structure of coils is designed and experiments prove its feasibility.
