One of these testing methods, eddy current, has been widely used for metal thickness measuring because of its good sensitivity, high test speed , non-contact and other advantage. The principle of eddy current testing is that, when the test coil is close to the metal conductor with alternating current, the eddy current would be inducing in the conductor, and correspongdingly, the eddy current would affect the original magnetic field, the result is the coils impedance and inducing voltage changed.

其中涡流无损检测技术具有灵敏度高、检测速度快、非接触等特点而广泛应用于金属厚度检测，它的原理是当载有交变电流的检测线圈靠近金属导体时在导体中产生涡流，该涡流又影响原磁场，使得线圈的阻抗和感应电压发生变化，通过分析阻抗或感应电压的变化来获得被测导体的信息。
