Abstract
The invention relates to a portable device for the non-destructive examination of a surface along a line, by means of at least one detection probe displaced along said line and guided by a guide removably fixed on said surface, wherein said guide has a length such that any portion of said line of comparable length presents a negligible variation in curvature, said probe is mounted in a probe-holder adapted to be displaced by hand and connected to said guide in rigid manner parallel thereto and in loose manner transversely to said guide, and means are provided for indicating, at each instant of a displacement of said probe-holder along said guide, the position of the probe-holder on the latter. The invention is particularly applicable to the verification of the riveted joints of aircraft fuselages.
