What Are the Influencing Factors of Different Structural Designs of Ultrasonic Transducers
Ultrasonic transducer, also called ultrasonic vibrator, is one of the most widely used energy conversion devices at present. As a device that can convert high-frequency electrical energy into mechanical energy, it converts the input electrical power into mechanical power and then transmits it out, and it consumes a lot of energy. With a small part of the power, ultrasonic transducers are widely used in the medical industry as well as in agriculture, national defense, biomedicine and scientific research.
1. Ultrasonic transducer has its own independent subject status
Its content involves physics, chemistry, optics, wave mechanics, electronics, mathematics, and signal processing. The direction of ultrasonic transducer research is to study the characteristics of acoustic impedance, impulse response, frequency response, impedance matching, acoustic structure, transducing material and vibration mode that meet the requirements of engineering use as much as possible, and design and coordinate these basic characteristics. To achieve the best conversion between electricity and sound.
The ultrasonic transducer designed based on years of production experience has the advantages of high efficiency, large amplitude, low equilibrium temperature, and good temperature stability. The comprehensive small-signal test and high-power driving inspection of each transducer before leaving the factory ensures the product quality is more guaranteed, eliminating your worries.
2. Influencing factors of ultrasonic transducers
According to the introduction of ultrasonic transducer equipment, specifically speaking, there are structures, piezoelectric ceramics, material matching, and manufacturing processes. Moreover, if the thickness is different, then the electrical parameters of the transducer are significantly different. If it is used as a heat meter, the main influencing factors are the piezoelectric ceramic material and the manufacturing process. The ultrasonic transducer is a device that converts electrical energy into mechanical energy, and a device that converts electrical energy and sound energy through the piezoelectric effect. It is called a piezoelectric transducer. It consists of a central piezoelectric ceramic element, front and rear metal covers, and prestressed Composed of screw, electrode sheet and insulating tube. According to different structural designs, it also has a great influence on their form and performance.
The influencing factors of ultrasonic transducers include structure, piezoelectric ceramics, material matching and manufacturing process, etc. Moreover, if the thickness is different, then the electrical parameters of the transducer are significantly different. If it is used as a heat meter, the main influencing factors are the piezoelectric ceramic material and the manufacturing process.
Manufacturers of ultrasonic transducers believe that the difference is mainly in the ultrasonic frequency and its power, because there are obvious differences in this aspect. In addition, the internal circuit of the transducer, that is, the main control board and the matching inductor are also different. They cannot be mixed, otherwise, there will be problems.
