Description:
The function of the ultrasonic transducer is to convert the input electrical power into mechanical power (ultrasonic waves) and then pass it out, while consuming a small portion of the power itself.
Ultrasonic transducers, the technical problem to be solved is to design an ultrasonic transducer with a large distance and frequency bandwidth.
The transducer consists of a housing, a matching layer, a piezoceramic disk transducer, a backing, an extraction cable, and a Cymbal array receiver. The piezoelectric ceramic disk transducer is made of PZT-5 piezoelectric material with polarization direction polarization. The Cymbal array receiver consists of 8 to 16 Cymbal transducers, two metal rings and rubber gaskets. The working distance of the invention is greater than 35 m, the frequency bandwidth reaches 10 kHz, and the long-distance target moving at high speed can be detected.

What is ultrasonic Converter?
The converter is aptly named because it receives electrical energy from the power supply and converts it into mechanical vibrations.
How does it work?
When alternating voltage at a frequency of 20,000 Hz is applied to the converter it physically vibrates at that same frequency.
What is a converter made up of?
An electrostrictive transducer consisting of one or more disks of piezoelectric material sandwiched between two metal sections.
The entire assembly is resonant at a predetermined frequency, and its length is acoustically equal to one-half wavelength at the applied frequency.
