<p>A displacement transducer (10) utilizes a torsional strain waveguide (20) having a magnetic member (17) that is adjustably positioned along the length of the waveguide, when an electrical current pulse is passed along the waveguide (20) and reaches the magnet (17) a torsional strain wave is created in the waveguide (20). The torsional strain wave will be reflected back toward a mounting end of the waveguide (20) where a converter (32) is positioned. A waveguide mounting block (25) supports the waveguide (20) at the mounting end, provides a reflection point for the torsional strain waves, and is precisely positioned a distance from the signal sensor (32) that is equal to distance traveled by the torsional strain wave in the waveguide during one-half of the signal lobe time period.</p> |
