Abstract
A magnetostrictive waveguide type position measuring system wherein the wire waveguide is mounted within a small diameter brass tube which, in turn, is mounted by way of resilient suspension components within a rigid outer tube affixed to a position reference frame. The resilient components isolate the waveguide from relatively high frequency shock inputs characteristic of rough environment applications. The waveguide is made of rolled and drawn wire with a round section, but the terminal ends are gradually reconfigured from round to flat, rectangular sections and are sandwiched between acoustic dampening pads to reduce or eliminate sonic reflections.
