Abstract

The invention relates, in particular, to an instrument for measuring length, comprising an inductive sensor comprising an elongate body and a tip that is movable along a longitudinal axis. The body contains windings and defines a first cavity receiving a magnetic core. The instrument further comprises a casing which extends the body along the longitudinal axis, and which defines, together with the body, a second sealed cavity containing the tip. The capacity of the casing to resiliently deform along the longitudinal axis is greater than the capacity of said casing to resiliently deform along axes that are orthogonal to said longitudinal axis.
