How to use the STONE display, STM32 microcontroller

The human ear can hear the frequency of sound waves for 20HZ ~ 20KHz. when the vibration frequency of sound waves is greater than 20KHz or less than 20Hz, we can not hear the sound waves. Therefore, we put the frequency higher than 20KHz sound waves called "ultrasonic". Because of its good directionality, strong penetrating ability, easy to get more concentrated sound energy, in the

USER'S GUIDE - Ultrasonic Processors & Equipment

The ultrasonic power supply converts 50/60 Hz line voltage to high frequency electrical energy. This high frequency electrical energy is transmitted to the piezoelectric transducer within the converter, where it is changed to mechanical vibrations. The vibrations from the converter are intensified by the probe, creating pressure waves in the

Ultrasonics - an overview | ScienceDirect Topics

Ultrasonic methods use a beam of mechanical vibrations of wavelength in the range –10 mm (, frequencies in the range 500 kHz to 10 MHz). Being mechanical vibrations, the particles of the specimen are displaced temporarily as the wave passes through, but the displacement is very small and the specimen is not damaged. Several types of wave motion are possible, the most important for NDT
