Abstract:
A position detector apparatus having a magnetostrictive wire extending through a measurement field with at least one magnet moveable through the measurement field for providing disturbances in the magnetostrictive wire, the apparatus comprising:an outer magnetic transmissive tube having a substantially linear sidewall extending between opposed first and second ends; a magnetostrictive wire fixedly mounted in and completely contained within the outer tube; pickup means, mounted within the outer tube and coupled to the magnetostrictive wire, for outputting signals propagating along the magnetostrictive wire; circuit means, disposed completely within the outer tube, for coupling electrical signals to the magnetostrictive wire and the pickup means and for transmitting electric signals from the magnetostrictive wire and the pickup means; and fitting means, fixedly mounted in the first end of the outer tube and containing a plurality of pins electrically engagable at one end to conductors extending from the circuit means, for connecting to external conductors.
