Ultrasonic transducer
Sep 17, 2018

The function of the ultrasonic transducer is to convert the input electric power into mechanical power (i. E. ultrasonic) and then transmit it, while consuming a small part of its own power.

The technical problem of ultrasonic transducer is to design an ultrasonic transducer with large operating range and wide bandwidth.

The transducer consists of a shell, a matching layer, a piezoelectric ceramic disc transducer, a backing, a lead-out cable and a Symbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-5 piezoelectric material with thickness polarization. The Cymbal array receiver consists of 8-16 Cymbal transducers, two metal rings and rubber washers. The operating range of the invention is greater than 35m, and the frequency bandwidth reaches 10kHz, which can detect long-distance targets with high-speed movement.
