Abstract:
A multi-measurement apparatus using a search-coil type sensor includes: sensor modules, each of which has one or more sensors including respective housings having respective inner spaces, respective cores formed to be inserted into the inner spaces of the housings, and respective coils which are each wound around a portion of an outer circumferential surface of each of the housings, the portion corresponding to a position of each of the cores; impedance matching units that are connected to a plurality of the sensors, respectively, and perform impedance matching; and amplifiers that are connected to the impedance matching units, respectively, and amplify a fine current and voltage generated during approach of objects to the sensors.
