Abstract:
Simulation model of analog part of measurement path of a flaw detector designed for application in automated systems of eddy current testing, as well as virtual stand and procedure for its testing were developed. The developed model was used for studying the transient processes in the flaw detector analog path for different types of input eddy current transducers. Investigation results can be applied for correction of the algorithms for automatic calibration and processing the information signals and taking decisions in automated systems of eddy current testing. 12 Ref., 9 Fig.
Keywords: automatic eddy current flaw detector, eddy current signal, simulation model, amplitude and phase modulation, transient process
