The amplitude of ultrasonic cell crushing processor | ultrasonic disperser| ultra sonicator usually refers to the amplitude of ultrasonic transducer and amplitude transformer.
The amplitude of ultrasonic cell crushing processor | ultrasonic disperser| ultra sonicator usually refers to the amplitude of ultrasonic transducer and amplitude transformer.In general, the frequency ranges from 19.5kHz to 21.5kHz, and the amplitude ranges from 40 microns to 80 microns. Because of its high frequency, it is out of the frequency range of most measuring instruments. The amplitude is small and the measurement accuracy is very high. It is difficult to measure because of the inability of common test methods to deal with it. Generally, it can only be measured by laser vibrometer, and good results can be obtained. However, the laser vibration measuring equipment is expensive and complex to operate, not to mention the general production units, even professional research and design units are rarely equipped, it is impossible to universal application.
As we all know, there are four parameters to describe any ultrasound. In other words, the effect of ultrasound depends only on four parameters, namely time, power, frequency and amplitude. The first two parameters are very convenient for control, adjustment and display, which are well understood by equipment producers and users and have been paid enough attention to. They are also adjustment parameters in daily operation of equipment. The amplitude (displacement) of ultrasonic vibration is the key index of ultrasonic equipment, and it is the most difficult physical quantity to measure and understand. Apart from the experts and scholars, not to mention the users of the equipment, even most of the equipment manufacturers, do not care much about it. We counted most of the ultrasonic random equipment operating instructions, there is little about the ultrasonic amplitude, including the physical significance of amplitude, amplitude control and adjustment.
The vibration amplitude of ultrasonic cell crushing processor | ultrasonic disperser| ultra sonicator directly represents the output energy of ultrasonic wave and is related to the strength of related materials and the service life of the whole machine. The importance of ultrasonic equipment cannot be overemphasized, either for manufacturers or users of ultrasonic equipment.

For ultrasonic vibration system, the main index is called ultrasonic sound intensity I in terms of energy transfer. It refers to the energy transmitted per square centimeter per second perpendicular to the direction of travel of a traveling wave, i.e
I = 1/2 rho omega factor 2 c
P is the density of the material
C is the velocity of ultrasonic wave propagation in the material
Omega is angular frequency
Factor is ultrasonic amplitude
Obviously, as the amplitude of the wave increases, the energy of the wave doubles as a square.
