Abstract:
An ultrasonic transducer is provided comprising a transducer housing, a piezoelectric assembly, and a seating assembly. The transducer housing includes a front end, a rear end opposite the front end, and an ultrasonic window positioned at the front end. The piezoelectric assembly is positioned within the transducer housing and comprises a piezoelectric assembly substrate and a piezoelectric laminate formed over a front surface of the assembly substrate. The seating assembly is arranged to secure the piezoelectric assembly within the transducer housing such that at least a portion of the piezoelectric laminate is aligned with the ultrasonic window. The transducer housing, the assembly substrate, and the seating assembly are preferably constructed of high temperature and high pressure materials characterized by substantially equivalent coefficients of thermal expansion. The piezoelectric laminate may include a piezoelectric aluminum nitride layer and the assembly substrate may comprise a material selected from the group consisting of tungsten carbide, silicon carbide, silicon nitride, and graphite.
