Patent

CA 2407247

The invention relates to a measuring sensor (1) for measuring positive and negative elongations on cylindrical or profiled bodies (6). The measuring sensor (1) consists of more than two parts and is essentially annular and has at least one tensioning element (7, 15). Two segments (2, 3) that can be tensioned are provided with a recess on the longitudinal center on the internal contour (22), said recess being disposed opposite the direction of tensioning (S) and accommodating a protruding elastic element (8) with a measuring element (10). Said recesses can be pressed non-positively onto the surface of the body (6). The segments (2, 3) of the multi-part measuring sensor (1) that are diagonally opposite can be tensioned with their both ends by means of exchangeable and/or adjustable lateral guide members (4, 5, 26, 38) for the body to be measured (6).

La présente invention concerne un capteur de mesure (1) servant à mesurer les expansions positives et négatives de corps cylindriques ou profilés (6). Le capteur de mesure (1) est composé de plus de deux parties, a une forme sensiblement annulaire, et comprend au moins un élément d'expansion (7, 15). Deux segments extensibles (2, 3) présentent chacun au milieu de leur longueur, sur leur contour interne (22), un évidement, lesdits évidements étant opposés dans la direction d'expansion (S), et destinés à recevoir une partie élastique en saillie (8) avec un élément de mesure (10), et pouvant être comprimés par liaison de force sur la surface du corps (6). Les segments (2, 3) diagonalement opposés du capteur de mesure (1) composé de plusieurs parties, peuvent être étirés à leurs deux extrémités par l'intermédiaire d'organes de guidage latéraux (4, 5, 26, 38) interchangeables et/ou réglables, destinés au corps (6) faisant l'objet de la mesure.
