The apparatus includes a sensor unit, a bobbin coil, a power supply unit, and a signal reception unit. The sensor unit is configured such that a plurality of magnetic sensors is arranged thereon and formed to be cylindrical. The bobbin coil is wound around the outside surface of the sensor unit. The power supply unit applies direct current (DC) power to the sensor unit and alternating current (AC) power to the bobbin coil. The signal reception unit quantifies a signal from the sensor unit. The sensor unit detects the distribution of a magnetic-field attributable to the crack in the small-bore piping system based on the AC power applied to the bobbin coil.

Abstract: If surface defects, near surface defects, or internal defects of a ferromagnetic substance object, a paramagnetic substance object, or a mixture object of ferromagnetic and paramagnetic substances are not quantitatively analyzed, the detected results can be differently analyzed depending on the knowledge or skill of an inspector.

The induced current applier applies a line or surface current to an object that is to be measured by using an alternating current (AC) having a frequency varying depending on a depth to be measured. The magneto-electric converter senses a magnetic field generated from the object by the Hn e or surface current and generates a magnetic field sensing signal corresponding to a strength of the sensed magnetic field.
