Piezo electric actuator housing in a magnetostrictive device

This invention relates to linear position transducers of the type comprising a linear magnetostrictive wire into which a signal is induced by applying a torsional strain along the wire and by action of a piezo electric actuator in contact with the wire. In particular, the invention relates to an improved housing for holding the piezo electric actuator in mechanical contact with the wire. An improved piezo electric actuator housing for use in a magnetostrictive device containing a piezo electric actuator and a magnetostrictive, where the improvement is a substantially one-piece container having a slot positioned therein, where the piezo electric actuator and the magnetostrictive wire are partly positioned in the slot, and an elastomeric cushion is positioned in the slot so that the magnetostrictive wire is mechanically coupled to the piezo electric actuator in the slot.
