Zusammenfassung:	A nondestructive sensor tube inspection probe (1) for examining the condition of a wall of a tube (6) from an interior thereof. The probe comprisesa probe body (14) having an axis extending along a direction of travel through the tube (6) anda centering seal (31) extending around an entire circumference of the probe body and biased radially outward from the probe body (14). The centering seal has a plurality of circumferential segments that, respectively, only partially extend around the circumference of the probe body and make contact with an inside of the wall of the tube (6) to be inspected with each of the segments being biased outward around a circumference of the probe body by a force. The force is separately applied to each of the segments with the same pressure by an axially reciprocal plunger (37) which is connected to each of the segments.
