quality control links in the manufacturing of metal parts such as bearings, rings, and auto parts;

Colleges and universities, scientific research and experiments, etc.

Operating Principle

Eddy current testing technology is based on the principle of electromagnetic induction, which loads an excitation signal into the probe coil, and when the probe approaches the metal surface, the alternating magnetic field around the coil generates an induced current on the metal surface. For flat metals, the direction of the induced current is a concentric circle of coils, shaped like a vortex, which is called an eddy current. The magnitude, phase and flow pattern of eddy currents are affected by the conductivity of the specimen. Eddy currents also generate a magnetic field, which in turn changes the impedance of the detection coil.

Therefore, when there is a defect on the surface or near the surface of the conductor or the measured metal material changes, the strength and distribution of the eddy current will be affected and cause changes, which will cause changes in the Voltage and impedance of the detection coil.
