Pulsed Eddy Current Measurement of Lift-Off
AIP Conference Proceedings, 2006It is observed that the slope of pulsed eddy current signals at the Lift‐Off point of Intersection (LOI) depends strongly on the lift‐off. The behaviour of the LOI slope is studied under varying test conditions. The signal response is curve‐fitted to a circuit equivalent non‐linear model using the Levenberg‐Marquardt algorithm and the LOI slope is ...

Pulsed Eddy-Current Interaction with Subsurface Cracks
1999Calculations have been carried out to evaluate pulsed eddy-current interaction with a planar crack in a conductor. The field is excited by a coil carrying current pulses while crack signals are detected by measuring changes in the magnetic field above the conductor or by monitoring variations in the induced emf across the coil.

Investigation into the Depth of Pulsed Eddy-Current Penetration
1981Pulsed eddy-currents have been used successfully for a number of years to measure the wall thickness of thin-wall tubing. In studies of 88.9-mm (3.50-in.)-diameter stainless-steel tubing, wall thicknesses in the 0.254 to 0.762 mm (0.010 to 0.030 in.) range have been measured with an accuracy of ±10%.

Pulsed Eddy-Current Testing of Steel Sheets
1981This is a brief report on some early work on the testing of steel sheets using pulsed eddy currents. Penetration up to about 10 mm has been achieved and some artificial defects have been observed. Longer pulses are to be employed for deeper penetration, and more work done on the observation of defects. Some theoretical work is also reported.
