Abstract

Appareil de protection d’extensomètre Un aspect de l’invention concerne un appareil de protection d’extensomètre 10 à contact comprenant un premier corps 11 adaptée à être solidaire d’une portion d’un bras 1 d’extensomètre E comprenant une surface de contact 110 et un deuxième corps 12 comprenant une surface de contact 120 en contact avec la surface de contact 110, et une portion d’attache 124 d’un couteau 14. L’appareil comprend en outre un dispositif de collage 13 exerçant une force de maintien collant le premier corps 11 au deuxième corps 12, permettant une fonction de protection mécanique contre une force de séparation par le détachement du premier corps 11, et deuxième corps 12, l’un de l’autre lorsque la force de séparation est exercée au-delà de la force maintien. Figure à publier avec l’abrégé : Figure 1Extensometer protection device One aspect of the invention relates to a contact extensometer protection device 10 comprising a first body 11 adapted to be secured to a portion of an extensometer arm 1 E comprising a contact surface 110 and a second body 12 comprising a contact surface 120 in contact with the contact surface 110, and an attachment portion 124 of a knife 14. The device further comprises a gluing device 13 exerting a holding force gluing the first body 11 to the second body 12, allowing a mechanical protection function against a separation force by the detachment of the first body 11, and second body 12, from one another when the separation force is exerted au- beyond the maintaining force. Figure to be published with the abstract: Figure 1
