The E-type probe, also known as a cross-coil probe or rotating magnetic field probe, is suitable for flat material defect detection. It can perform a comprehensive magnetic saturation inspection in one go. Equipped with rolling wheels and a work light, it enhances the inspection speed. Pole spacing: 110mm, lifting force: AC≥9kg, weight: 2kg. A device independently made using this probe is called a rotating magnetic field flaw detector. It utilizes two crossed cores and AC phase-shifting technology to generate a composite rotating magnetic field that varies over time, magnetizing the workpiece comprehensively in one go. This probe features fast inspection speed and high detection quality.
