(FR) capteur DE DÉPLACEMENT
Abstract
(EN)
A displacement, strain, and/or force sensor assembly (10, 110) has a mounting structure (12) with an anisotropic stiffness to facilitate the measurement of displacements, strains, and/or forces along the X-axis, while minimizing errors due to undesired displacements, strains, and/or forces along the Y- and Z-axes, and rotations about the X-, Y-, and Z-axes. A pedestal (30, 130) configured to respond to axial displacements along the X-axis is centrally disposed on the X-axis of the mounting structure (12), and a displacement or strain sensor (38) is coupled to the pedestal (30) to provide a measure of the displacements, strains, and/or forces. Contact pads (14, 114) are formed on opposite ends of the X-axis of the mounting structure, to enable the displacement and/or strain sensor assembly to be secured to an application structure.
(FR)
L'invention concerne un ensemble capteur de déplacement, de contrainte et/ou de force (10, 110) possédant une structure de montage (12) avec une rigidité anisotrope pour faciliter la mesure de déplacements, de contraintes, et/ou de forces le long de l'axe X, tout en minimisant les erreurs dues aux déplacements, contraintes, et/ou forces indésirables le long des axes Y et Z, et/ou rotations autour des axes X, Y et Z. Un piédestal (30, 130) configuré pour réagir aux déplacements axiaux le long de l'axe X est disposé au centre sur l'axe X de la structure de montage (12), et un capteur de déplacement ou de contrainte (38) est couplé au piédestal (30) pour constituer une mesure des déplacements, contraintes et/ou forces. Des plages de contact (14, 114) sont formées sur des extrémités opposées de l'axe X de la structure de montage, pour permettre de fixer l'ensemble capteur de déplacement et/ou de contrainte à une structure d'application.
