1. An eddy current probe assembly for analyzing an article, the eddy current probe assembly comprising:
a housing comprising a coolant passage extending into the housing, the coolant passage forming a loop within the housing including ports out of the housing, the coolant passage allowing coolant flow through the housing;
at least one eddy current probe disposed on or within a housing surface, the at least one eddy current probe being supported by a printed circuit board, the at least one eddy current probe being thermally coupled with a first portion of the coolant passage using at least a first surface of the at least one eddy current probe, wherein a portion of the housing separates the at least one eddy current probe from the first portion of the coolant passage; and
a barrier layer disposed on a second surface of the at least one eddy current probe opposite the at least one eddy current probe first surface where the at least one eddy current probe separates the barrier layer from the portion of the housing.
