  • Method for measuring a wall thickness of a hollow vane
    Patent number: 6806703
    Abstract: An eddy current detector includes two poles aligned in the direction of extension of partitions located behind a wall, wherein the thickness must be measured, but which interfere with the measurements. The influence of the partitions is decreased by the core of the detector including two poles aligned in the direction of the extension of the partitions and by using a logical system to correct the results obtained according to preliminary results obtained on a reference surface.

  • Hollow vane wall thickness measurement method
    Publication number: 20030184287
    Abstract: An eddy current detector (4) comprises two poles aligned in the direction of extension of partitions (3) located behind a wall (2) wherein the thickness must be measured, but which interfere with the measurements. The influence of the partitions (3) is decreased if the core (6) of the detector (4) comprises two poles aligned in the direction of the extension of the partitions (3) and if a logical system is used to correct the results obtained according to preliminary results obtained on a reference surface.
