Vortex Flaw Detector

Vortex flaw detector is a vortex tester with a single sensor input, single-channel double frequency. Eddy current testing machine can examine large areas very quickly, and it does not require the use of coupling liquids. In addition to finding cracks, Eddy Current can also be used to check metal hardness and conductivity in applications where those properties are of interest and to measure thin layers of nonconductive coatings like paint on metal parts.

  • FET-5.6

Product Description

Introduction profile:



Vortex flaw detector can connect the rotating type sensor and probe type sensor, suitable for arranging on the automatic or semi-automatic testing line to detect crack and heat treatment. 


Eddy current flaw detector is based on the physics phenomenon of electromagnetic induction. In an eddy current probe, an alternating current flows through a wire coil and generates an oscillating magnetic field. If the probe and its magnetic field are brought close to a conductive material like a metal test piece, a circular flow of electrons known as an eddy current will begin to move through the metal like swirling water in a stream. That eddy current flowing through the metal will in turn generate its own magnetic field, which will interact with the coil and its field through mutual inductance. Changes in metal thickness or defects like near-surface cracking will interrupt or alter the amplitude and pattern of the eddy current and the resulting magnetic field. This in turn affects the movement of electrons in the coil by varying the electrical impedance of the coil. The eddy current instrument plots changes in the impedance amplitude and phase angle, which can be used by a trained operator to identify changes in the test piece.


Vortex flaw detector is a vortex tester with a single sensor input, single-channel double frequency. Eddy current testing machine can examine large areas very quickly, and it does not require the use of coupling liquids. In addition to finding cracks, Eddy Current can also be used to check metal hardness and conductivity in applications where those properties are of interest and to measure thin layers of nonconductive coatings like paint on metal parts.
