Examples
- Round steel rods - the eddy current testing method with probe coil
圆钢点式线圈涡流探伤检验方法 - Probe coil clearance
探头线圈间隙 - Eddy current nondestructive testing ( ecndt ) is widely used to detect the thinness and defects of the sample , because of its characteristics of non - contact , high sensitivity and ease of detection . the principle of ecndt is that : when a probe coil with the ac exciting source is put near a sample , eddy current will be produced in the sample which will conversely affect the impedance of the coil according to the farad theorem . any un - uniformity in the sample will change the impedance of the coil and the output voltage
涡流无损检测技术具有灵敏度高、检测速度快、非接触等特点广泛应用于厚度检测和缺陷探伤，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。
