Multi - Frequency Intelligent Portable Raman Spectrometer Eddy Current Flaw Detector

Mitech MET Series Portable Eddy Current Flaw Detector intelligent, portable, multi-frequency Working Principle The eddy current detection technique is based on the principle of electromagnetic induction, and the excitation signal is loaded into the probe coil. When the probe is close to the metal surface, the alternating magnetic field around the coil will generate the induced current on the metal surface.For flat metal, the flow of induced current is a coil concentric
