Eddy Current Automatic Flaw Detector

The eddy current automatic flaw detector induces eddy currents on the surface of conductive materials through an alternating magnetic field and identifies defects by detecting changes in the eddy currents. It is used for online detection of surface cracks and corrosion in metal pipes and rods, ensuring material integrity.
Selection
When selecting, consider the conductivity of the material being tested, match the probe frequency and fill factor. Set the phase amplitude according to the defect type, and combine automatic sorting and alarm functions to adapt to the speed and environmental conditions of the production line.
