APPARATUS FOR METAL CRACK DETECTION USING ELECTROMAGNETIC WAVE AND CUTOFF CAVITY PROBE

摘要

The present invention relates to a conductor crack detection device and a crack detection method using electromagnetic waves and a blocking cavity probe. According to the present invention, there is provided an apparatus for detecting a crack in a conductor using an electromagnetic wave and a blocking cavity probe, comprising an opening for contacting a conductor plate and measuring whether the conductor plate is cracked, a blocking cavity probe coupled to the blocking cavity probe and electromagnetic wave An electromagnetic wave signal generator for generating an electromagnetic wave signal generator, a variable reactance for adjusting the electromagnetic field distribution in the blocking cavity probe, a variable resistor for adjusting the sensitivity of the blocking cavity probe by changing a resistance value of the blocking cavity probe, a current flowing in the blocking cavity probe A meter for measuring , a control unit that measures the amount of current when a conductive plate without cracks is contacted while varying the variable reactance, and obtains a reference current value using the change amount of the measured current, and the reference current is used and a crack determination unit for judging whether the conductor plate corresponding to the measurement target is cracked.
