ABSTRACT:
An eddy current sensor probe which includes first and second rigid end portions coupled together with a central portion comprising a flexible membrane. The flexible membrane includes indentations comprising sensor supporting regions. A differential pressure is applied across the membrane to position the sensors in a favorable location for collecting data related to the condition of the wall portion of hollow tubes.
