Eddy current magnetic particle flaw Detector

The eddy current magnetic particle flaw detector induces eddy currents on the surface of conductive materials through an alternating magnetic field. Defects disturb the magnetic field, causing magnetic particles to accumulate and reveal the flaws. It is used to detect surface defects in metals, such as cracks and pores, and is suitable for the online inspection of components such as steel pipes and shafts.
Selection
Based on the material's conductivity, select the probe frequency. Use the magnetic particle method for ferromagnetic materials and the eddy current method for non-ferromagnetic materials. Consider the detection depth and defect size to match the probe specifications. Environmental temperature affects instrument stability, so the appropriate protection level must be matched.
