A miniature urethane molded acoustic transducer

Abstract

The development of a reliable miniature molded transducer for the \nWilliams/Koehler acoustic current meter, BASS (Benthic Acoustic Stress Sensor) \nls documented. The procedures developed and components selected for manufacturing \nthe transducer assemblies are documented as well as some of those \nrejected. \nEngineering tests performed to ensure reliable performance in the field \nare outlined and discussed as well. \nThe transducers are now routinely molded with great success (over 1200 \noperational transducer months to date) and commercial sources are being investigated.
