A system (20) for monitoring deformation of a substantially cylindri-cal casing (14). The system (20) includes at least two strings (22) of interconnected sensors (24) that are wrapped around the casing (14) so as not to intersect one anoth-er. At least one of the strings (22) includes a series of at least two segments (S). The series of segments (S) includes a segment (S) arranged at one wrap angle (.theta.) and an-other segment (S) arranged at a different wrap angle (.theta.).

La présente invention se rapporte à un système (20) destiné à contrôler la déformation dun tubage sensiblement cylindrique (14). Le système (20) comprend au moins deux chaînes (22) de capteurs interconnectés (24) qui sont enroulées autour du tubage (14) de manière à ne pas se croiser. Au moins une des chaînes (22) comprend une série dau moins deux segments (S). La série de segments (S) comprend un segment (S) disposé selon un angle denroulement (?) et un autre segment (S) disposé selon un angle denroulement (?) différent.
