Ultrasound Equipment

In order to introduce ultrasound energy into a washing system, an ultrasound transducer and an ultrasound motor force or “generator” are required. The generator provides electrical energy at the desired ultrasound frequency. The ultrasound transducer converts the electrical energy from the ultrasound generator into mechanical vibrations.

Ultrasound Generator

The ultrasound generator converts electrical energy from the power line, which is a 50 or 60 Hz alternating current, to electrical energy at the ultrasound frequency. This is carried out in a large number of different ways by the various ultrasound equipment industries. Ultrasound current generators have a solid technological state.

There have been many recent innovations in ultrasound generators which can increase the effectiveness of ultrasound cleaning equipment. These include square wave output, which slowly or rapidly pulses the ultrasound energy at intervals and modulates the frequency of the generator output around the central operating frequency by “extending it in a curved line”. The most advanced ultrasound generators area able to adjust a variety of output parameters in order to customise the ultrasound energy output to meet the task.

Square Wave Output

Applying a square wave signal to an ultrasound transducer results in an acoustic output rich in harmonics. The result is a multifrequency cleaning system that vibrates simultaneously at different frequencies, which are harmonics of the basic frequency. The multifrequency operation offers the benefit of all the frequencies combined in a single ultrasound washing tank.

Impulse

In the impulse operation, the ultrasound energy is switched on and off at a rhythm that may vary by one every umpteenth second to several hundred per second.
