【 摘 要 】

A contactless measurement technique is providing to examine products during the process; a modular design of eddy current micro sensor was developed using various materials. The sensor consists of two parts, a singleturn excitation coil and an anisotropic magneto-resistance (AMR) sensor. The sensor is intended to be applied for the detection of cracks in ferrous and non-ferrous metals. The AMR sensor detects the change of the magnetic field induced in a sample by the excitation coil. Initial investigations were conducted to prove the capability of the completed eddy current micro sensor.
