Modified eddy current probe having a faraday shield

A modified eddy current (MEC) probe system comprising:

• a plurality of MEC probes configured to cooperate with each other, each MEC probe including:
• a probe body having a bore formed therein;
• a printed circuit board (PCB) assembly including a circuit board defining a plane and having a plurality of electronic components mounted thereon, the PCB assembly configured for mounting within the bore of the probe body;
• and
• a coil board assembly electrically connected to the PCB assembly, the coil board assembly defining a plane and including:
• a first coil board layer;
• a second coil board layer bonded to the first coil board layer;
• a transmitter coil formed on an outside surface of the first coil board layer,
• a Faraday shield formed on an outside surface of the second coil board layer;
• and
• a sensor coil formed on one of an inside surface of the first coil board layer and the second coil board layer, such that the sensor coil is positioned between the first coil board layer and the second coil board layer,
• wherein the plane of the coil board assembly is arranged orthogonally to the plane of the circuit board;
• wherein the Faraday shields are configured to isolate a propagating transverse electro-magnetic (TEM) field emitted by each MEC probe and to one of prevent and reduce coupling of electro-magnetic fields from the transmitter coil to the plurality of electronic components mounted on the PCB assembly.
