| Popis: | Recently, several research works exploring the potential of utilizing acoustic waves for the measurement of many physical phenomena has been published. Propagation characteristics of standing acoustic waves at the boundary between two solid edges within a closed resonance tube are a function of displacement. The possibility of designing a waveguide acoustic transducer for linear displacement measurement was investigated. Signal conditioning and processing is carried out using LabVIEW VIs. Linear range of operation was found 10 cm. Results obtained show that such transducer may be integrated with other primary nonelectrical sensors in order to get an electrical read out, and to realize linear positional feedback control. |
