The function of the ultrasonic transducer is to convert the input electrical power into mechanical power (i.e. ultrasonic waves) and then transmit it out, while consuming a small part of the power itself.
Ultrasonic transducer, the technical problem to be solved is to design an ultrasonic transducer with large operating distance and wide frequency range.
The transducer consists of a housing, a matching layer, a piezoelectric ceramic disc transducer, a backing, an outlet cable and a 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 to 16 Cymbal transducers, two metal rings and rubber gaskets. The invention has an action distance greater than 35m, a frequency band width of 10kHz, and can detect high-speed moving long-distance targets.
