Sažetak
There is an intensive research of pulsed eddy current as a new nondestruc-tive technique. Broadband nature of pulsed excitation potentially enables ex-traction of more information about tested object in a single measurement. Furthermore, lower power consumption of the measurement probe and shorter inspection time can be achieved comparing to the multifrequency si-nusoidal eddy current inspection. On the other hand, there are some obsta-cles to wider application of pulsed eddy currents. Design of electronic in-strumentation for proper detection of pulsed eddy current signals is con-strained with requirements for both wideband and high dynamic range. Fi-nally, in practical use, problems might occur with data interpretation (in time or frequency domain) for operators familiar with impedance plains found in standard eddy current applications. In this paper, we present results of our research and development work on methods for nondestructive inspection based on pulsed eddy current and discuss advantages and prob-lems associated with such type of excitation. The first method is applied to determination of a thickness of an aluminum plate by measuring an excitation coil current. Furthermore, we present results of the first research of ferromagnetic tube wall thickness measurement utilizing pulsed remote field eddy current (RFEC) technique.
