Miniature Urethane Molded Acoustic Transducer

摘要

The development of a reliable miniature molded transducer for the Williams/Koehler acoustic current meters, BASS (Benthic Acoustic Stress Sensor) is documented. The procedures developed and components selected for manufacturing the transducer assemblies are documented as well as some of those rejected. Engineering tests performed to ensure reliable performance in the field are outlined and discussed as well. The transducers are now routinely molded with great success (over 1200 operational transducer months to date) and commercial sources are being investigated. (Author)
