Non-destructive evaluation of ferromagnetic material thickness using Pulsed Eddy Current sensor detector coil voltage decay rate

Pulsed Eddy Current Non-destructive Testing and Evaluation: A Review

Pulsed eddy current (PEC) non-destructive testing and evaluation (NDT&E) has been around for some time and it is still attracting extensive attention from researchers around the globe, which can be witnessed through the reports reviewed in this paper. Thanks to its richness of spectral components, various applications of this technique have been proposed and reported in the literature covering ...

Chirp and Multi-frequency Eddy Current Non-destructive Evaluation

This paper describes an eddy current (EC) based non-destructive testing system used for experimental verification of optimized chirp signal. The time-frequency content of the EC driving signal is synthesized with respect to material properties. We are expecting an improvement in sensitivity of crack and corrosion detection.

Eddy Current Pulsed Thermography for Non- Destructive Evaluation of Carbon Fibre Reinforced Plastic for Wind Turbine Blades

Pulsed Eddy Currents: A New Trend in Non-destructive Evaluation of Conductive Materials

Abstrac t Pulsed eddy current (PEC) is a new technique of non-destructive material evaluation (NDE). In comparison with other eddy current techniques, PEC uses pulsed excitation that is characterized by wide frequency content and thus the response carries more complex information about a tested object. PEC method is used in many NDE common applications such as inspection of defects, measurement...

Simultaneous Measurement of Material Properties and Thickness of Carbon Steel Plates Using Pulsed Eddy Currents

OF CARBON STEEL PLATES USING PULSED EDDY CURRENTS V.O. de Haan and P. de Jong 1 BonPhysics Research and Investigations BV, Putterhoek, The Netherlands; 2 Röntgen Technische Dienst bv, Rotterdam, The Netherlands Abstract: It is well know from literature that Pulsed Eddy Currents generated by switching off a stationary current through a coil above a carbon steel plate can be used to measure the t...
