  • Construction structure corrosion measurement sensor assembly and method for measuring corrosion by using same
    Patent number: 11360051
    Abstract: The present disclosure provides a construction structure corrosion measurement sensor having accuracy higher than that of conventional sensors, and a method for measuring corrosion by using the same. To this end, the present disclosure provides a sensor assembly including an eddy-current sensor including an insulator a coil surrounding the outer periphery of the insulator. The present disclosure also provides a construction structure corrosion measurement method including the steps of: positioning a sensor assembly next to a rebar inside a construction structure in parallel with and adjacent to the rebar; applying a voltage to the sensor assembly; measuring a voltage generated by an eddy current resulting from the adjacent rebar; and conducting measurement at a predetermined time interval so as to measure a voltage change.
    Type: Grant
