Abstract
A magnetostrictive position sensor achieves an improved signal to noise ratio by implementing several electronic control features, including: enclosing a waveguide within an approximately tubular return conductor, adjusting the energy of an interrogation pulse and then clamping the waveguide, tracking the peak voltage of a sensed signal, cutting off the signal of a pickup during the time period outside of a signal time frame, adjusting the pass band of a filter based on an interrogation rate and waveguide length, zeroing and scaling a signal without digitizing the signal, and avoiding noise from an interrogation voltage generator.
