Application Cases

Ultrasonic standing wave levitation is an important means of non-contact and container-free processing. The principle involves generating high-frequency piston-like vibrations at the radiating end of an ultrasonic transducer to form an acoustic field in the medium. By placing a reflector in the path of the sound wave, the reflected wave superimposes with the incident wave to create a high-intensity standing wave acoustic field. Objects placed within this standing wave field will levitate under the influence of the radiated acoustic pressure. This technique is widely used in chemical synthesis, biological research, and pharmaceutical production.

Aigtek offers a wide range of high-voltage amplifiers that are widely used in ultrasonic testing. These amplifiers can be matched to the electrical parameters of different transducers to provide suitable power amplification.

Experiment Name: The Application of High-Voltage Amplifiers in Ultrasonic Standing Wave Levitation

Experiment Principle:

The radiating end of an ultrasonic transducer generates high-frequency piston-like vibrations to form an acoustic field in the medium. A reflector placed in the path of the sound wave causes the reflected wave to superimpose with the incident wave, creating a high-intensity standing wave acoustic field. Objects within this field will levitate due to the radiated acoustic pressure.

Experimental Process:

The ultrasonic standing wave levitation system primarily consists of a signal generator, power amplifier, ultrasonic transducer, mechanical support, and reflector.

A function signal generator produces specific periodic waveforms to provide electrical signals of various frequencies to the ultrasonic transducer. This signal is amplified by the ATA-2032 high-voltage amplifier to drive the transducer. Based on the converse piezoelectric effect, the transducer converts the electrical signal into a high-frequency acoustic signal. The acoustic signal superimposes multiple times with the reflector to form a standing wave, which levitates the object.
