Abstract
The present invention provides methods and systems for sensory elements for placement within a probe that includes at least one receiving coil disposed within a pulsed eddy current probe, and at least one sensing element disposed within a pulse eddy current probe. The at least on sensing element may be disposed on a printed circuit board.
Claims5
Sensory elements for placement within a pulsed eddy current probe, comprising:
- a first receiving coil and a second receiving coil that is wound over and around the first receiving coil and at least one sensing element disposed on a circuit board within a cavity of the receiving coils between the first receiving coil and the second receiving coil;
- the pulsed eddy current probe, comprising:
- a first magnetizing yoke having a first leg and a second leg with each leg having an interior side and an exterior side;
- a second magnetizing yoke having a first leg and a second leg with each leg having an interior side and an exterior side;
- an inner cavity formed within the interior side of the second leg and the first leg of the first magnetizing yoke and the interior side of the second leg and the first leg of the second magnetizing yoke;
- a coil assembly comprising a generation coil positioned within the inner cavity and a pair of positioning bores, wherein the second leg of each of the at least two magnetizing yokes is positioned within the pair of positioning bores of the coil assembly, the generation coil contains an opening;
- and
- the first receiving coil, the second receiving coil and at least one sensing element disposed on the circuit board and within the opening of the generation coil.
