Ultrasonic transducer manufacturing process:
The transducer consists of a shell, a matching layer, a piezoelectric ceramic disc transducer, a backing, a lead-out cable and a Cymbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-5 piezoelectric material polarized in the thickness direction, and the Cymbal array receiver is composed of 8 to 16 Cymbal transducers, two metal rings and rubber gaskets.
