The function of the ultrasonic transducer is to convert the input electrical power into mechanical power (that is, ultrasonic wave) and then transfer out, and its own consumption of a small part of the power. The transducer consists of a housing, a matching layer, a piezoceramics disk transducer, a backing, a lead-off cable and a Cymbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-5 piezoelectric material polarized in thickness direction. The Cymbal array receiver consists of 8 to 16 Cymbal transducers, two metal rings and rubber washers.
