| Abstract: | Based on the principle of eddy current sensing, the performance of the eddy current sensor probe is investigated for the application of measuring the gaps between curved surfaces. The magnetic field generated by the curved coil is calculated by modifying the formulation that for the planar coil. And then, with the analysis and evaluation of the measurement characteristics of the curved coil, the parameters of the sensor coil is optimally designed. Furthermore, several factors that influence the measurement of the curved surfaces with eddy current sensor is analyzed and tested to give some advices and references. |
