Abstract

L'invention a trait à un système de mesure de distance encapsulé. Elle a pour objet un tel système dans lequel un appareil d'exploration est guidé parallèlement à une échelle portant des graduations. Les éléments d'étanchéité 10, 11 recouvrant la fente longitudinale dans la capsule 1 du système de mesure, entre lesquels pénètre le bras d'entraînement 9, sont constitués par deux bandes se recouvrant ou des bandes profilées en forme de lèvres en matériau élastique, qui forment par recouvrement une surface d'étanchéité 23 et auxquelles les côtés écartés du recouvrement sont réunis de façon hermétique le Ion de la fente à la capsule du système de mesure. Application : notamment au réglage de coordonnées de chariots de machines et de tables de mesure.
