Abstract
L'invention concerne un dispositif extensomètre (1) destiné en particulier à un compteur d'essieux (91) et comprenant - au moins un élément extensomètre (5), en particulier une fibre optique (6) comportant une fibre à réseau de bragg (6a, fbg), - un support (2) sur lequel est fixé l'élément extensomètre (5), et - une structure à surveiller (4), en particulier un rail de chemin de fer, sur laquelle le support (2) est fixé. Au moins une partie du support (2) est maintenue par la structure (4) dans un état déformé élastiquement lorsque le support (2) est fixé sur la structure (4). L'invention est caractérisée en ce que le support (2) est formé d'une première pièce de support (t1) et d'une deuxième pièce de support (t2) espacées l'une de l'autre, et en ce que l'élément extensomètre (5) comporte au moins un premier point de fixation (7) qui est fixé à la première pièce de support (t1) et au moins un deuxième point de fixation (8) qui est fixé à la deuxième pièce de support (t2) et une partie centrale (5a) située entre les points de fixation (7, 8) qui n'est fixée ni à la première ni à la deuxième pièce de support (t1, t2). L'invention propose un ensemble extensomètre, facile à utiliser, dans lequel une dégradation peut être détectée de manière fiable et un état d'extension de l'élément extensomètre est plus facile à spécifier.
