摘要
电涡流探头是电涡流传感器的核心部件。本文从电磁场理论出发,通过二维有限元法构建电涡流探头模型,运用COMSOL Multiphysic软件对电涡流探头的电磁特性进行仿真,研究线圈结构对电涡流传感器性能的影响。依据仿真设计一种反射式环形结构电涡流传感器探头,并进行实验验证。
Current probe is the core component of eddy current sensor. Based on electromagnetic field theory, this paper modeled an eddy current probe by means of 2D finite element method, simulated the electromagnetic properties of the eddy current probe by using COMSOL Multiphysic software, studied the structures of coil that affect the performance of the eddy current sensor. Finally, designed a ring shape reflective eddy current sensor probe and experiments have been done.
