FLAW DETECTING SYSTEM OF MICRO-TYPE AND MANUFACTURING METHOD OF SENSOR PART

摘要

PURPOSE: A method for manufacturing a micro-type defect detecting system and a sensor unit is provided to measure the defective part of a pipe-shaped object by using a defect detecting device. CONSTITUTION: A method for manufacturing a micro-type defect detecting system and a sensor unit comprises a sensor unit(10), a signal processing unit(11), a data collection unit(12), and a data processing unit(13). The sensor unit senses a signal of magnetic field occurred from an object. The signal processing unit first filters and amplifies the sensed magnetic field signal. The data collection unit collects two or more data.
