Claim 0:
1. An in-line inspection (ILI) tool comprising: a tool body; a plurality of sensing segments, each sensing segment having an array of sensing elements and a drive conductor with an arc-shaped segment; a plurality of armatures, each controlling retraction and protraction of a respective sensing segment with respect to the tool body; an impedance instrument having a signal generator configured to generate an electrical current at a first excitation frequency, said signal generator electrically connected to provide the electrical current to the drive conductor of each of the plurality of sensing segments, and a plurality of parallel sensing channels, each sensing channel dedicated to a sensing element of the plurality of sensing segments and configured to simultaneously measure real and imaginary components of an impedance associated with the respective sensing element at the first excitation frequency.
