60KHz Eddy Current Testing Probes Electrical Conductivity Meter Non-Ferrous Metals
HEC-102 eddy current electrical conductivity meter, measurement technology of eddy current, which are designed for quick & convenient measurement of material property, such as material separate,quality control,material state check and so on. The products use the electromagnetism testing principle, can testing objects focus on non-ferromagnetic materials
Ⅰ,Principle
Eddy current exam is an NDT method established on the basis of electromagnetic induction principle; it is suitable for the conductive materials. Put the conductor in the alternating magnetic field, if inductive current exists, namely eddy current. On account of the change of each conductor’s own factors (for example: conductivity, magnetic conductivity, shape, size and flaw, etc), will cause the change of the current, so we can use this phenomenon to judge the conductor’s character or state and whether flaw exists.
Eddy current test is to put the conductor close to the alternating current coil, the coil establishes alternating magnetic field, this alternating magnetic field transits the conductor, and has the electromagnetic induction with it, establishes eddy current in the conductor. The current in the conductor also can produce its own magnetic field and can change the alternating magnetic field to be strong or weak, then causes the change of the voltage and R resistance. Therefore if the conductor’s surface or the near surface has flaw or the metal material changes, the intensity and the distribution of the eddy current will also change, so as the change of the voltage and R resistance, according to this change, the eddy current may indirectly know about the flaw in the conductor and whether the performance of the metal material changed.
