Sažetak
In conventional applications of the remote field eddy current technique, a probe with low frequency sinusoidal excitation is used for measurement of ferromagnetic tube wall thickness. An additional probe with high frequency excitation is required for measurement of the tube inner diameter (electrical caliper). In this paper, this is illustrated with results of finite element analysis. However, the waveform of the pulse driving current and shorter probe length potentially allow the measurement of the inner diameter and the wall thickness with the same probe. We present results of our experiments on ferromagnetic tubes with internal and external defects that confirm applicability of the pulsed remote field technique for measurement of the both quantities.
