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.
