MAGNETIC NON-DESTRUCTIVE INSPECTION APPARATUS CAPABLE OF RAPIDLY INSPECTING OBJECT

摘要

PURPOSE: A magnetic non-destructive inspection apparatus is provided to rapidly inspect an object by simply changing a scan range. CONSTITUTION: A magnetic non-destructive inspection apparatus includes a sensor module for detecting a magnetic field induced by scanning an inspected wire through a non-contact scheme. An amplifying circuit(14) is provided to amplify the magnetic field detected by the sensor module. The sensor module includes a coupling antenna(11) for inducing current through a capacitive coupling of the inspected wire. A bypass capacitor(12) is provided to bypass the current induced to the coupling antenna(11) to an earth. A magnetic sensor(13) detects the magnetic field generated by an induced current around the coupling antenna(11).
