A modified eddy current (MEC) probe includes a probe body having a bore formed therein. A printed circuit board (PCB) assembly includes a circuit board defining a plane, has a plurality of electronic components mounted thereon, and is configured for mounting within the bore of the probe body. A coil board assembly is electrically connected to the PCB assembly, defines a plane, and includes 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. The plane of the coil board assembly is arranged orthogonally to the plane of the circuit board.

A modified eddy current (MEC) probe includes a probe body having a bore formed therein. A printed circuit board (PCB) assembly includes a circuit board defining a plane, has a plurality of electronic components mounted thereon, and is configured for mounting within the bore of the probe body. A coil board assembly is electrically connected to the PCB assembly and comprises a coil board defining a plane, a transmitter coil formed on a first side of the coil board, and a sensor coil formed on second side of the coil board. The plane of the coil board is arranged orthogonally to the plane of the circuit board.

Modified eddy current probe for low conductivity surfaces

A fully integrated wireless spread-spectrum sensor incorporating all elements of an 'intelligent' sensor on a single circuit chip is capable of telemetering data to a receiver. Synchronous control of all elements of the chip provides low-cost, low-noise, and highly robust data transmission, in turn enabling the use of low-cost monolithic receivers.
