When an electrical signal is applied to the ultrasonic transducer, it vibrates in the characteristic frequency range and generates sound waves. These sound waves will move, as long as any obstacle occurs, these sound waves will be sent back to the transducer data. Finally, these data are converted into electrical signals.
Here, the principle of ultrasonic transducer evaluates the time interval between sending a sound wave and obtaining an echo signal. The ultrasonic transducer probe emits an ultrasonic pulse at a frequency of 40 kHz, which moves in the air. These transducers are more popular than infrared sensors because they are not affected by black matter, dust, smoke, etc. Stork, as one of the most reliable handheld ultrasound probe companies in China, can provide you with many practical ultrasound probe types, such as phased array transducers.
In recent years, the application of composite devices in which micro-machined parts replace ordinary solid ceramic discs or plates has increased. They are tiny piezoelectric ceramic cylinders fixed in an epoxy resin matrix.
Composite components can provide higher bandwidth and higher sensitivity in many fault detection applications. When it is stimulated by electrical pulses, this piezoelectric component generates sound waves, and when it is vibrated by the return signal, it generates voltage. The specific element is not damaged by the wear plate or acoustic lens and is supported by a damping material that silences the transducer after the sound pulse is emitted. The ultrasonic sub-component is installed in a housing with a suitable electrical coupler. All angle beams, delay lines, common contacts, and immersion ultrasonic transducers use this main model.
The phase alignment probe used in the imaging system can easily integrate multiple individual transducer components into one design. The principle of dual-crystal ultrasonic transducers is usually used in corrosion inspection systems. The difference is that they have different transmitting and receiving parts, separated by sound barriers and integral delay lines to guide and combine sound energy, rather than wear plates or lens.
