Eddy current testing is currently used to determine the physical characteristics of a conductive specimen and to detect defects by measurements of electrical impedance of an eddy current probe. In this study we developed two systems of coils allowing to determine properties of conductive coatings and ...

One of the major causes of error in conductivity measurements using the eddy-current method is known as "lift-off." Lift-off is the spacing between the electrical coil used to measure conductivity and the conductive material upon which measurements are to be taken. Lift-off can be caused by...
electrical conductivity, it requires ECT probes to operate at high testing frequencies to inspect these materials. The testing frequency was chosen to operate at a frequency within the near electrical resonance band to enhance the sensitivity and signal-to-noise ratio of the ECT probe [22]. The ...
Copper, while being an extremely good electrical conductor, has a problem that the torque delivered by the system employing the copper disc is neither relatively flat or constant for the range of exercise intended; nor is the torque provided by the eddy current/copper disc system controllable ...
