1. A probe-holder carriage, comprising:
a probe-holder frame, sliding means connected to said probe-holder frame and suitable for cooperating with a resting surface in a material with high magnetic permeability so as to permit a sliding of the carriage on said surface, at least one permanent magnet, suitable for interacting magnetically with said resting surface for an anchorage of the carriage to the resting surface, said permanent magnet being fitted so as to graze the resting surface with one of its poles, wherein: said probe-holder frame defines a central housing and comprises support means suitable to support at least one probe inside said central housing, said sliding means comprise sliding skates hinged to the probe-holder frame so as to be free to oscillate about an oscillation axis in relation to said frame to adapt to any curvature of the resting surface, wherein the at least one permanent magnet is supported by a respective sliding skate, the sliding skates are fitted with wheels suitable to permit a sliding of the carriage in one direction only, the at least one permanent magnet is kept in place at a predefined distance from the resting surface, and the rotation axis of the wheels is orthogonal to the oscillation axis of the sliding skates. |
