Abstract
An ultrasound transducer includes a resonant driving assembly having an ultrasound radiating surface covered with a propagation disc of impedance matching material. The resonant driving assembly and propagation disc are housed in a polymeric or stainless steel enclosure. All exposed surfaces of the enclosure, resonant driving assembly, and disc are covered with a coating of polyparaxylylene to make the transducer substantially impervious to industrial chemicals.
