Title (EN) STRAIN SENSOR WITH MEASUREMENT DISCRIMINATION ACCORDING TO THE DEFORMATION DIRECTION
(FR) CAPTEUR DE DEFORMATION PERMETTANT UNE DISCRIMINATION DE MESURE EN FONCTION DE LA DIRECTION DE LA DEFORMATION
Abstract:
(EN) A passive strain sensor (C2) includes a system for detecting a variation in the distance between two points or regions of a structure, and a carrier (1) having first and second portions (1a, 1b) configured for attachment to said points or regions. Said system comprises a measuring assembly (13) carried by the first portion (1a) and actuatable only in one measurement direction to measure and store a measurement associated with at least one strain in a measurement direction, and an actuating device (12) comprising an intermediate assembly (15) with an actuating member (15c) of the measuring assembly (13), and an actuating assembly (14) having a push portion (14c) opposite the intermediate assembly (15) and configured such that the actuating member (15c) is moved relative to the measuring assembly (13) only when the second portion (1b) moves in the measurement direction.
(FR) Un capteur passif (C2) de déformation (s) comprend un système de détection de variation de distance entre deux points ou zones d'une structure et un support (1) possédant des première et seconde parties (1a, 1b) configurées pour une fixation auxdits points ou zones. Ledit système comprend un ensemble de mesure (13) porté par la première partie (la) et actionnable uniquement dans un sens de mesure pour mesurer et mémoriser une mesure associée à au moins une déformation dans une direction de mesure, et un dispositif d' actionnement (12) comprenant un ensemble intermédiaire (15) possédant un élément d' actionnement (15c) de l'ensemble de mesure (13), et un ensemble d' actionnement (14) possédant une partie de poussée (14c) en regard de l'ensemble intermédiaire (15) et configurée pour que l'élément d' actionnement (15c) soit déplacé par rapport à l'ensemble de mesure (13) uniquement lorsque la seconde partie (1b) se déplace dans le sens de mesure.
