Abstract
The utility model relates to an on-line nondestructive testing diagnostic device which can quantitatively detect broken wire and sections inside and outside cable wires, which aims at providing a computer flaw detector for cable wires, which can process flaw indication of the cable wires at a high speed and can store and display the flaw indication of the cable wires. When the cable wires to be detected in the computer flaw detector for the cable wires have relative movement with a magnetic sensor, the magnetic sensor transfers the change status of leakage magnetic field of the cable wires into analog voltage signals, analog signals collected by the magnetic sensor are transferred into digital signals after passing through a data converter, the digital signals are computationally analyzed by the CPU of a computer, and the digital signals can be stored in a data storage device after comparative judgment and analogously displayed on a display apparatus. After the flaw detector is used, undetected situations can not occur, the detection is more accurate, the judgment is easier, and the operation is convenient and simple. Therefore, the flaw detector can be widely applied to various industries manufacturing, using and managing cable wires.
