What Is An Ultrasonic Amplitude Measuring Machine?

An ultrasonic amplitude measuring instrument is the special equipment for ultrasonic amplitude measurement, which can be used to measure the output amplitude of ultrasonic transducers, ultrasonic horns, and tool heads.

Ultrasonic amplitude refers to the amplitude of ultrasonic equipment. Usually, the frequency is between 10kHz and 60kHz, and the amplitude is between 1μm and 200μm. Due to the high frequency and small amplitude, the measurement is also large.

The frequency of ultrasonic welding equipment is beyond the frequency range of most measuring instruments.

The amplitude of ultrasonic welding equipment also puts forward high requirements for measurement accuracy.

Commonly used test methods are powerless to it, so it is difficult to measure. Generally, only a laser vibrometer can be used to measure, and better results can be obtained. But laser vibration measuring equipment is expensive and complicated to operate. Production units and professional research and design units are rarely used.

Features

Sophisticated design: the device is small in size, only composed of a meter head and a bracket, no external power supply is required.

Reasonable structure: suitable for measuring the output amplitude of various ultrasonic welding equipment.

Simple operation: simple steps to use.

Accurate measurement: the measurement accuracy reaches 1 micron.

Scope of application

The output amplitude measurement of ultrasonic plastic welding, spot welding, cutting, sonochemistry, cell crushing, and other equipment can also be used to measure the output amplitude of ultrasonic transducers, horns, and tool heads independently.

Significance

For any ultrasonic device, whether it is ultrasonic plastic welding or ultrasonic sonochemical applications, ultrasonic power is related to three parameters: frequency, load characteristics, and amplitude. When the ultrasonic equipment and the object of action are determined, the frequency and load characteristics remain unchanged, and the only parameter that affects the ultrasonic power is the amplitude. Because the amplitude is difficult to measure, most equipment manufacturers and users do not know much about it.

Most of the manuals for ultrasonic random equipment have few descriptions of the ultrasonic amplitude, including the physical meaning of the amplitude, the control and adjustment of the amplitude, and the relationship between the amplitude and the actual effect.

The amplitude of ultrasonic vibration directly represents the magnitude of ultrasonic output energy and is also related to the strength of related materials and the service life of the whole machine. With the continuous development of ultrasonic application technology, people have deepened their understanding of ultrasonic waves, and providing users with accurate ultrasonic amplitude parameters has become more and more important for ultrasonic manufacturers or ultrasonic users.
