1. What is an ultrasonic generator?

  Ultrasonic generator is a kind of equipment that converts the mains power into the corresponding high-frequency AC power of the transducer, to drive the transducer to work. It is an important part of high-power ultrasonic system. It can also be called electronic box, ultrasonic driving power supply and ultrasonic controller.

 2. Ultrasonic generator working principle

 The input of the ultrasonic generator is a signal with a fixed frequency. The signal waveform is uncertain and can be sinusoidal or pulsed, but its frequency is fixed as the frequency of the transducer, generally 20, 25, 28, 33, 40, 60KHZ, etc. Through the internal conversion of the ultrasonic generator, its output is power signal, frequency tracking signal, etc.

 As the output signal presents an unstable state with the change of input signal, some ultrasonic generators also contain feedback parts, which are mainly reflected in two aspects:

 On the one hand, the change of the input signal leads to the instability of the output power, resulting in irregular mechanical vibration of the transducer and poor cleaning effect. After adding the feedback part, the power feedback signal adjusts the output power so that it does not change with the change of the input signal and presents a stable state. The regular mechanical vibration of the transducer makes the cleaning effect better.

 On the other hand, the efficiency is the highest when the frequency of the transducer is at the resonant frequency point, but in practice, it cannot always work in the best state due to various reasons. Therefore, the feedback part plays its role to provide frequency tracking signal, and the signal sent by the control signal generator is always at the resonant point of the transducer to make it always work in the best state.

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.

 1. The working principles of the ultrasonic transducer

 The ultrasonic transducer uses the piezoelectric effect of the piezoelectric ceramic with the same resonant frequency to convert electrical energy into mechanical vibration. Ultrasonic wave is usually generated by ultrasonic generator, which is converted into mechanical vibration by high frequency ultrasonic transducer, and then ultrasonic wave can be generated by ultrasonic export device and ultrasonic receiving device. Therefore, as an energy conversion device, the function of the ultrasonic transducer is to convert the input electrical power into mechanical power (ultrasound) and then transmit it out, while it consumes a small part of the power.

 The structure of ultrasonic transducer mainly has several major components such as housing, acoustic window (matching layer), piezoelectric ceramic disc transducer, backing, lead-in cable, and receiver. Among them, the piezoelectric ceramic disc transducer has the same role as most transducers, mainly used to transmit and receive ultrasonic waves. The ultrasonic receiver is on top of the piezoelectric ceramic disc transducer, which is mainly composed of the lead-out cable, the transducer, the metal ring and the rubber gasket, and receives the Doppler callback generated outside the frequency band of the piezoelectric ceramic disc transducer Signal.

 2. The application of ultrasonic transducer

 Ultrasonic transducers have a very wide range of applications. According to the application industry, they can be divided into industry, agriculture, transportation, life, medical treatment and military. According to the functions realized, it can be divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc. According to the working environment, it can be divided into liquid, gas, organism, etc. By nature, it can be divided into power ultrasound, detection ultrasound, ultrasound imaging, etc.

Medical ultrasonic transducer is a device that converts ultrasonic frequency electric energy into ultrasonic energy in ultrasonic processing equipment. Currently, there are two types of ultrasonic transducers that are widely used. The types of ultrasonic transducers are as follows:

 1. Magnetostrictive ultrasonic transducer

 The first type of the medical ultrasonic transducer is the magnetostrictive transducer, which can be divided into two types according to the material. One is made by stacking sheets of metal materials with magnetostrictive properties (such as nickel, iron-cobalt alloys and aluminum-iron alloys, etc.). It is characterized by high mechanical strength, large emission power, stable performance, medium electroacoustic efficiency, and the working frequency range is generally below 50KHZ. It includes two structural types, window type and annular ultrasonic transducer. The other one is made of ferrite powder material by press molding and sintering. It is characterized by easy molding, high material resistivity, and higher electro-acoustic conversion efficiency than the former. Its working frequency can reach 100KHZ, but its mechanical strength is lower than the former, and its transmitting power is smaller. Magnetostrictive transducers also have the characteristics of high Curie point, low power supply voltage and easy cooling.

 2. Piezo ultrasonic transducer

 The piezo ultrasonic transducer can also be divided into two categories according to the type of material. One type is made by cutting and grinding a single crystal material with piezoelectric properties (such as quartz crystal) in a certain direction. It is characterized by high transmitting power and high electroacoustic efficiency, and is suitable for working in the high frequency range (up to several gigahertz). However, due to the high impedance, the supply voltage is relatively high and inconvenient to use. The other type is piezoelectric ceramics formed by pressing, sintering, and polarizing powdered materials. It is characterized by easy molding, high electroacoustic efficiency, low impedance, and lower power supply voltage than the former, and it is also suitable for high-frequency range work. In addition, a large number of sandwich structures are currently used in the low frequency range (several kilohertz to tens of kilohertz). The piezo ultrasonic transducer utilizes different polarizations and combinations to easily implement various vibration modes to meet the needs of different ultrasonic processing. The disadvantage of this type is low tensile strength. However, due to abundant material sources and low prices, applications are gradually increasing.

Ultrasonic transducer is the heart of ultrasound products and the electromechanical equipment is especially important. It converts the high-frequency and high-voltage power supplied from the electric box into high-frequency mechanical vibration, and the maximum power output can reach thousands of kilowatts, so its stability and power output are very important to the operation performance of the whole machine, and it is also the most valuable equipment. It is the key to reflect the value of the entire machine. The following is a method to detect the quality of medical ultrasonic transducers.

 1. Parameter detection of medical ultrasonic transducer

 Check whether the parameters of the transducer match the parameters of the electric box, and whether the desired effect can be achieved.

 2. It can be identified from the manufacturing process and appearance of the medical ultrasonic transducer

 It directly reflects the importance of technology to product quality, and the quality of products with good craftsmanship and appearance will naturally be better (but not absolutely). Moreover, the design process directly affects the product quality.

 3. It can be identified according to the process design and materials used for medical ultrasonic transducers

 However, this requires a good understanding and rich experience in the material of an ultrasonic transducer of the type used in medical. Whether the design is reasonable or not should be determined according to the selected materials. The quality of the materials directly affects the quality of the product. Pirated products with the same appearance are not necessarily good in quality. If the material of the same specification is from different place, the quality is also very different. If the material is bad, even the best technology cannot make good products.

 4. On-machine test of medical ultrasonic transducer

 (1) Stability test (simulated aging test): Test the power output stability of the electric box and the transducer with the rated load of the equipment.

 (2) Overload operation test: test the stability of product quality and its service life. This test only needs to equip it with the rated load and ensure it run continuously for 8 hours.

 (3) Power output test: It can detect the matching of the transducer and the electric box, and at the same time reflect the load power output of the electric box and the medical ultrasonic transducer. The larger the mold, the better the work effect, and the stronger the power output. (The current can only reflect the output efficiency, not the power of the device).

 The above is about the method to identify the quality of an ultrasonic transducer of the type used in medical. Of course, some of the methods need to be tested on the machine. I hope this article can help you. If there are any questions about the ultrasonic transducer, welcome to consult us Wuhan BBT Mini-Invasive Medical Tech. Co., Ltd.

BBT Ultrasonic Transducer

https://www.bbt-medical.com/products/bbt-ultrasonic-transducer/

Wuhan BBT Medical is a professional ultrasonic transducer supplier and manufacturer. Our homemade ultrasonic transducer is a device that converts electrical energy into mechanical energy, usually made of piezoelectric ceramic sheets. The piezoelectric effect of the material converts electrical signals into mechanical vibrations. The electric oscillation signal from the excitation power supply will change the electric field in the energy storage element of the ultrasonic transducer, causing it to enter a vibration state, thereby driving the medium in contact with the mechanical vibration system of the transducer to vibrate. When the vibrating blade is in contact with the tissue, it will break the protein hydrogen bonds of the tissue, and the tissue protein cells will be denatured to form a sticky clot, which can cut hemostasis (vessels below 5mm).

  How Does An Ultrasonic Transducer Work?

The ultrasonic transducer itself is not an energy generator, it is just an energy converter, which converts electrical energy into mechanical energy, and can convert a large amount of energy on the premise that the output matches the input well. A high AC voltage is applied to the transducer through the drive circuit to charge and discharge the capacitance of the transducer. Among them, the piezoelectric ceramic sheet undergoes simultaneous expansion and contraction under the action of an alternating electric field, generates longitudinal mechanical vibration and expands at the conduction shaft node. The bite force of the cutter head can reach the maximum 55.5KHz high frequency vibration. The cutter head contacts the tissue protein, breaking the hydrogen bond of the protein, reorganizing the protein structure, and deep coagulation to close the larger lumen, so as to achieve the effect of cutting, coagulating the tissue and stopping bleeding.

  Application of Transducer in Medical Field

Ultrasonic transducers are widely used in the medical industry and are continuously improved. From diagnostic tests that allow parents to see a newborn's heartbeat for the first time to surgical equipment that can treat rare cancers, ultrasound transducers play a key role in today's healthcare.

 Piezoelectric transducers generate ultrasonic waves because the material used to make the transducer vibrates when an AC voltage is applied. This vibration produces very high frequency pressure waves; the rate is 10MHz or higher. To generate ultrasound at these frequencies, most medical applications of ultrasound use lead zirconate titanate ceramics (PZT). These same materials can also work in reverse to detect ultrasonic waves and convert the energy of these waves into electrical signals.

 The most common use of ultrasound transducers in the medical field is ultrasound imaging. Use the echo time of the ultrasound and the Doppler shift of the reflected sound to create an image to determine the distance to the internal organs of the target and their movement.

 Another increasingly widespread application of ultrasound is ultrasound surgery. Ultrasound surgery is minimally invasive and precise enough to allow the surgeon to remove diseased or damaged tissue without affecting the surrounding area. This leads to faster recovery time and improved patient outcomes.

  Ultrasonic Transducer Working Principle

In the transducer probe are piezoelectric crystals, which will change shape when current is applied to them. Vibration or shape changes can produce sound waves that move outward. When they point to the human body, they pass directly through the skin into the internal anatomy.
