About ultrasonic transducer, the upper limit of its working voltage will be marked, so the specified voltage should not be exceeded, otherwise the ultrasonic transducer will be easily damaged. For example, if the ultrasonic transducer is indicated as PHA-34-12C, then its nominal working voltage is 1

Ultrasound is different from audible sound waves in that it can be focused and has the characteristics of concentrated energy. Piezoelectric ceramics or magnetostrictive materials can obtain high-power ultrasonic waves under the action of high-voltage narrow pulses, which can be focused and can be u

The frequency of the ultrasound that people can hear is 20Hz~2KHz, that is, audible sound waves. The sound beyond this frequency range, the ultrasound below 20Hz is called low-frequency sound wave, and the ultrasound above 20KHz is called ultrasound (ultrasound), the frequency of general speaking .T

Ultrasonic distance transducers are sensors developed using the characteristics of ultrasonic waves. Ultrasonic is a mechanical wave with a higher vibration frequency than sound waves. It is generated by the vibration of the transducer chip under the excitation of voltage. It has high frequency, sho

Ultrasonic waves propagate in a straight line. The frequency is the higher , the diffraction ability is the weaker, but the stronger the reflection ability. For this reason, ultrasonic sensors can be made using this property of ultrasonic waves. In addition, the propagation speed of ultrasonic waves

With the technological advancement of MEMS, laser technology, high-tech materials, etc., the research and development of ultrasonic sensors is showing a diversified trend. Some application biological materials are to simulate human skin and innovate on the tactile sense of ultrasonic sensors; some M

In the application of ultrasonic wind speed and direction sensor, the ultrasonic wind speed sensor has the characteristics of light weight, no moving parts, sturdiness and durability, and does not require maintenance and on-site calibration. It can output wind speed and direction at the same time. W

Piezoelectric ceramics or magnetostrictive materials can obtain high-power ultrasonic waves under the action of high-voltage narrow pulses, which can be focused, and can be used for welding integrated circuits and plastics. After the ultrasonic wave is focused, it has good directivity. When ultrason
