What is ultrasonic transducer?

Definition: An Ultrasonic Transducer refers to Capacitive Transducer or Piezoelectric Transducer that can convert electrical energy into ultrasound energy and vice versa. It is one of the types of sound-related transducers. The frequency spectrum range of this ultrasound or ultrasonic wave is over 20KHz and this is used at 200KHz based on the application.

These are used in non-destructive testing, measuring materials, and identifying small faults because of the lower wavelength of the ultrasound. These are important in sensors for level and flow measure, distance calculation, and also in biomedical, power, and other ultrasound applications. It has a wide range of applications in various fields.

Ultrasonic Transducer Working

When this transducer transmits the electrical signals onto the target, then the signal hits the object and returns to the transducer. Here distance of the object is calculated rather than the amplitude of the signal and sound quality. These transducers utilize ultrasonic waves to calculate a few parameters but are typically used in distance measurement.

This transducer depends on the sensitivity or resolution. The ability of the transducer to disconnect signals formed by the two close reflectors is called resolution. The ability of the transducer to detect the fault in the substances is known as sensitivity. An extremely damped transducer helps to lower the reflected signal and permits the transducer to study the closely spaced faults. To transducer should have higher resolution and sensitivity with large polarized ceramic materials and crystals to change its process.

Ultrasonic transducer consists of:

The ultrasonic transducer consists of a shell, an acoustic window matching layer, a piezoelectric ceramic disc transducer, a backing, an outlet cable and a Cymbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-5 piezoelectric material polarized in the thickness direction. The Cymbal array receiver consists of 8 to 16 Cymbal transducers, two metal rings and rubber gaskets. According to different designs, the main forms of ultrasonic transducers are: column type (NTK type), inverted horn type (Branson type), steel back cover type, and aluminum sheet type in the middle.

Working principle of ultrasonic transducer:

Ultrasonic sensors are sensors developed using the characteristics of ultrasonic waves. Ultrasound is a mechanical wave with a higher vibration frequency than sound waves, and ultrasonic transducers generally come in two forms: magnetostrictive and piezoelectric ceramics.

Working principle of piezoelectric ceramic ultrasonic transducer: Piezoelectric technology uses crystals with special electrical properties made of lead zirconate titanate. In a transducer, this crystalline material has two wires attached to it on opposite sides. The crystal and wiring are then assembled in a housing between two metal plates. When electricity flows through the wiring and into the crystal, the crystal rapidly changes shape and expands. When the current is terminated, the crystal returns to its original shape. Ultrasound transducers using this technology rapidly cycle an electric current through a crystal at a set frequency, creating a resonant effect.

How a magnetostrictive ultrasonic transducer works: Iron-rich metals expand and contract when exposed to a magnetic field. To exploit this behavior, a core of iron-rich metal is wrapped in copper wire. The component is then contained in a can. When electricity passes through a copper wire, the metal core expands and lengthens. Like piezoelectric transducers, current at a set frequency creates a resonant effect.

How to Evaluate the quality of the ultrasonic transducer?
First, it can be identified from the manufacturing process and appearance of the ultrasonic transducer; the ultrasonic transducer indirectly shows that the company pays attention to the quality of the product, and the production and quality with good technology and appearance will naturally be better . And the design process indirectly affects the quality of production.
Second, it can be identified based on the process design and application data of the ultrasonic transducer; however, this requires a good understanding of the transducer data and rich experience. Whether the design is reasonable should be determined based on the selection of data. The quality of the data indirectly affects the quality of the product, and it may not be copied according to the board. The origin of the data with the specifications is not the same, the quality varies greatly, and no matter how good the data is, it also makes a good product.
Third, parameter detection by impedence analyzer; test whether the parameters of the ultrasonic transducer can match the parameters of the electrical box, and whether it can achieve the desired effect.
Fourth, work on the ultrasonic welding machine
1-Power input experiment: This method can detect the match between the transducer and the ultrasonic generator, and at the same time can reflect the power input of the ultrasonic generator and the transducer load. The larger the mold belt, the better the task effect and the better the power input. Strong. (The current can only reflect the input efficiency and does not represent the power of the device)
2- Fluctuation experiment (imitation aging experiment): Take the equipment extra load to detect the power input fluctuation of the ultrasonic generator and transducer.
3- Overload operation test: test the fluctuation of product quality and life. This test only needs to take extra load to continue discontinuous operation for 8 hours.
