Abstract
A tube inspection unit () includes an eddy current probe (). The probe () has a plurality of inductors and a plurality of receivers. The receivers are magnetoresistances having a substantially linear functional zone. The inductors of the probe () are linked to a controller (). The controller () is programmed to inject, into the inductors, a voltage with a sinusoidal component and a nonzero direct-current component, such that the receivers have a polarization center situated inside the substantially linear functional zone.
