Eddy current inspection probe for inspecting multiple portions of a turbine blade having different geometric surfaces

An eddy current probe inspection unit for inspecting multiple portions of a turbine blade having different geometric surfaces, comprising:

• a shaft having a hollow main body and a probe tip connector secured toward an end of the shaft;
• an eddy current signal conduit connecting the probe tip connector with an output device;
• and
• a plurality of eddy current probe tips, each tip adapted to be received by the probe tip connector and having a different geometric configuration to inspect a different geometric surface of the turbine blade,
• wherein said eddy current probe tip includes at least one coil and a magnetically permeable nose pivotally mounted in front of the at least one coil, being dimensioned and configured to be placed in contact with material to be inspected, and the eddy current signal conduit directly connecting the probe tip connector to the output device.
