    摘要： A non-destructive test apparatus includes a drive coil and a resonant coil in working relation to the drive coil. The non-destructive test apparatus includes a voltage source coupled to the drive coil. The voltage source is configured to apply an alternating current signal to the drive coil. The non-destructive test apparatus includes a sensor coupled to the resonant coil. The sensor is configured to output sensor data indicative of a voltage induced in the resonant coil by the alternating current signal applied to the drive coil. The non-destructive test apparatus also includes a processor coupled to the sensor to receive the sensor data from the sensor. The processor is configured to determine, based on the voltage, a porosity of an item positioned in working relation to the resonant coil.

    摘要： If surface defects, near surface defects, or internal defects of a ferromagnetic su bstance object, a paramagnetic substance object, or a mixture object of ferromagnetic a nd paramagnetic substances are not quantitatively analyzed, the detected results can b e differently analyzed depending on the knowledge or skill of an inspector. A defect detection apparatus according to an exemplary embodiment of the pres ent invention includes an induced current applier, a magneto-electric converter, a signal processor, a signal converter, and a data processor. The induced current applier app lies 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 s trength of the sensed magnetic field. The signal processor filters and amplifies the ma gnetic field sensing signal and outputs a signal corresponding to amplitude of the filtere d and amplified signal. The signal converter converts the signal output from the signal processor into a digital signal. The data processor quantitatively converts an intensity of a magnetic field generated from the object into a numerical value based on the digital signal output from the signal converter.

    摘要： The invention relates to an inspection apparatus (ID) for inspecting a structural component (SC) to which access is restricted, comprising a movable unit (MU) including a superconductor (M) and an inspection device (1), a drive unit (DU) including a magnetic field generator (2) adapted to generate a magnetic field (MF), wherein said movable unit (MU) and said drive unit (DU) are arranged with a predetermined gap (G) therebetween for receiving said structural component (SC) and are coupled in a force-locking manner by means of the frozen magnetic flux, i.e. without a physical connection, between the magnetic field generator (2) and the superconductor (M). Thus, spaces or areas to which access is restricted can be inspected without the need of physically connecting the drive unit (DU) and the movable unit (MU).
