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 circular, shaped like a vortex, named as the eddy current.The size, phase and flow pattern of the eddy current are affected by the conductivity of the specimen.The eddy current also produces a magnetic field that in turn causes the impedance of the detection coil to change.

So when the conductor surface or near the surface of the defect or the measurement of metal materials change, the intensity and distribution of eddy currents will be affected by changes in the impact,Which in turn causes a change in the detection coil voltage and impedance.Eddy current testing is based on this change, the indirect feedback of the existence of defects within the conductor and the performance of metal materials have changed.
