Ultrasonic transducer composition:

Ultrasonic transducers are energy devices that convert electrical energy, mechanical energy, or acoustic energy from one form of energy to another, also known as ultrasonic transducers, also known as active sensors. One of the most mature and reliable is the device that converts electrical energy and acoustic energy by piezoelectric effect, also known as piezoelectric transducer.

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. A piezoelectric ceramic disk transducer is used as a basic ultrasonic transducer for transmitting and receiving ultrasonic signals; a Cymbal array receiver is located above the disk piezoelectric transducer as an ultrasonic receiver for receiving the disk Doppler echo signals outside the transducer band. 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.

Ultrasonic transducer operating temperature

Ultrasonic transducers generate heat when used, which is mainly caused by three causes. One is that the material to be heated or ultrasonically treated by the workpiece will heat up, or the mold (tool head) and the horn will heat up for a long time, and this heat will be transferred to the transducer. The second is the power loss of the transducer itself. Since the energy conversion efficiency is not 100%, the energy lost is inevitably converted into heat. The temperature rise will cause the ultrasonic transducer parameters to change, and gradually shift to the best matching state. What is more serious is that the temperature rise will cause the performance of the piezoelectric ceramic wafer to deteriorate. This in turn causes the ultrasonic transducer to work worse and heat up more quickly, which is a vicious circle. Therefore, we must give the ultrasonic transducer a good cooling condition, usually at room temperature and air cooling; if necessary, cold air cooling can also be used. Under normal conditions, the temperature rise caused by these two points is also normal, and under normal cooling conditions, there will be no major problems.
