| Abstract: | Abestract A new type of frequecy modulation (FM) eddy current transducer is intro-duced in this paper. Its sensing and reference coils of probe are made of differential con-struction. The probe and main frame link with optical fiber. The system stability,tem-perature drift rejection and anti-interference ability are contributed by all above technol-ogy. |
