There are many types of ultrasonic transducers, which can be divided into ultrasonic welding transducers, ultrasonic cleaning transducers, and ultrasonic cutting transducers according to the application. According to the power, there are 18k, 20K, 28K, and 35K ultrasonic transducers. Their resonant voltages are also different. In this regard, Wuhan BBT surgery equipments company will introduce to you what the working voltage of medical ultrasonic transducers is:
Ultrasonic scalpel is a high-frequency electrosurgical device, which is mainly used for cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and faster recovery after surgery. It acts on human tissues to cut and coagulate, and will not cause side effects such as tissue dryness and burns. There is no current passing through the body when the cutter head is working, which has a wide range of applications in the operating room, known as the bloodless scalpel.

Ultrasonic emitter, also known as ultrasonic drive power supply, electronic box, and ultrasonic controller, is an important part of the high-power ultrasonic system. The function of the ultrasonic emitter is to convert the mains electricity into a high-frequency alternating current signal matched with the ultrasonic transducer to drive the ultrasonic transducer to work. High-power ultrasonic power supply generally adopts the circuit form of switching power supply from the aspect of conversion efficiency. Ultrasonic power supplies are divided into self-excited and other-excited power supplies. The self-excited power supply is called ultrasonic analog power supply, and the other-excited power supply is called ultrasonic emitter.
Ultrasonic transducers emit ultrasonic waves, which can also be called mechanical waves. It has good directionality and strong penetrating ability, and it can spread in water and air. It can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization, disinfection, etc. The transducers commonly used in ultrasound are divided into magnetostrictive transducers and electrostrictive transducers according to the vibration excitation mode.

The ultrasonic transducer is composed of a central piezoelectric ceramic element, front and rear metal cover plates, prestressed screws, electrode sheets and insulating tubes. This kind of sandwich transducer (also known as: bolt-fastened transducer) generates stable ultrasonic waves when the load changes, and is the most basic and main method to obtain a power ultrasonic drive source.

The main consideration when using an ultrasonic transducer is the matching with the input and output ends, followed by mechanical installation and matching dimensions. The ultrasonic transducer frequency is relatively intuitive. The frequency refers to the frequency measured by the transmission line method with a frequency (function) generator, millivoltmeter, oscilloscope, etc., or the frequency measured with a similar instrument such as a network impedance analyzer. It is commonly referred to as small signal frequency. The customer connects the ultrasonic transducer to the drive power supply through the cable, and the actual working frequency can be measured when no load or on load is energized. Because the customer matching circuit varies, the same ultrasonic transducer in different drive power supply performance of the frequency is different, such frequency can not be used as the basis for discussion.
Ultrasonic level gauge is a non-contact instrument dedicated to continuous measurement of liquid level. It mainly sends out high-frequency ultrasonic pulses through an ultrasonic transducer. When it encounters the surface of the liquid level to be measured, the sound wave is reflected back, and part of the reflected echo is received by the transducer and converted into an electrical signal. The ultrasonic level gauge uses the time difference between sound wave emission and reception and the sound wave propagation speed to calculate the liquid level. Ultrasonic transducers are the core components of ultrasonic level gauges, mainly including piezoelectric transducers, sandwich transducers, cylindrical transducers, inverted horn transducers and other different types. The transducers of our company are mainly piezoelectric transducers. In order to enable users to have a more comprehensive understanding of the ultrasonic transducer, its working principle and main applications are introduced as follows.
The early medical ultrasound mainly focuses on ultrasound diagnosis. From ordinary black-and-white ultrasound to three-dimensional color ultrasound and then to four-dimensional color ultrasound, the development of ultrasound diagnosis has gradually matured and has also been widely used. With the gradual development of medical technology nowadays, traditional surgical procedures are gradually moving towards smaller wounds and less bleeding.
