Zusammenfassung:The invention relates, in particular, to an instrument (10) for measuring length, comprising an inductive sensor (11) comprising an elongate body (14) and a tip (17) that is movable along a longitudinal axis (15). The body (14) contains windings and defines a first cavity receiving a magnetic core. The instrument further comprises a casing (13) which extends the body (14) along the longitudinal axis, and which defines, together with the body (14), a second sealed cavity (16) containing the tip (17). The capacity of the casing to resiliently deform along the longitudinal axis (15) is greater than the capacity of said casing to resiliently deform along axes that are orthogonal to said longitudinal axis. L'invention concerne notamment un instrument (10) de mesure de longueur comportant un capteur (11) inductif comportant un corps (14) allongé et une pointe de touche (17) mobile selon un axe longitudinal (15). Le corps (14) contient des bobinages et délimite une première cavité recevant un noyau magnétique. L'instrument comporte en outre une enveloppe (13) qui prolonge le corps (14) selon l'axe longitudinal et qui délimite, avec le corps (14), une seconde cavité (16) étanche renfermant la pointe de touche (17). La capacité de déformation élastique de l'enveloppe, selon l'axe longitudinal (15), est supérieure à la capacité de déformation élastique de cette enveloppe selon des axes orthogonaux à cet axe longitudinal.
