A Brief Introduction To Ultrasonic Transducers

The function of an ultrasonic transducer is to convert the input electrical power into mechanical power (i.e. ultrasonic waves) and transmit it out, while consuming a small portion of its own power.
The technical problem to be solved with ultrasonic transducers is to design an ultrasonic transducer with a large operating distance and wide frequency band.
The transducer consists of a housing, matching layer, piezoelectric ceramic disc transducer, backing, lead out cable, and Cymbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-5 piezoelectric material polarized in the thickness direction. The Cymbal array receiver consists of 8-16 Cymbal transducers, two metal rings, and rubber gaskets. The working distance of the present invention is greater than 35m, the frequency band width reaches 10kHz, and it can detect high-speed moving long-distance targets.
