Ultrasonic Converters and Ultrasonic Transducers are one in the same. There is one Ultrasonic OEM, Dukane Corporation, that uses the term Transducer. All of the other ultrasonic OEM manufactures such as Branson, Sonics and Materials, Rinco, Telesonics and Herrmann refer to these as Converters or Konverters.
Converters or Transducers all do the same thing…convert electrical energy to mechanical movement…so we have our electrical charge being introduced across the surface of the ceramics at the desired frequency which in turn gives us a movement or vibration at the working end on the converter.
The converter is threaded onto a booster, which increases, decreases or just transfers the amount of movement from the face of the converter to the horn or Sonotrode as we call it.

The physical definition of a wave is that the transmission of vibration in an object forms a wave. There must be two conditions for the formation of such waves: one is the source of vibration and the other is the propagation medium. The classification of waves generally has the following types: First, classification according to the direction of vibration and the direction of propagation. When the direction of vibration is perpendicular to the direction of propagation, it is called a transverse wave. When the direction of vibration coincides with the direction of propagation, it is called a longitudinal wave. Second, according to the frequency classification, we know that the human ear sensitive hearing range is 20HZ-20000HZ, so the wave within this range is called sound wave. Waves below this range are called infrasound waves, and waves above this range are called ultrasonic waves.
Transducer working mode
Due to different processing methods and requirements, the working mode of the transducer can be roughly divided into continuous work (lace machine, CD set machine, zipper machine, metal welding, etc.) and pulse type work (such as plastic welding machine). Different working methods The requirements for the transducer are different. In general, continuous operation has almost no pause time, but the operating current is not very large, the pulse operation is intermittent, there is a pause, but the instantaneous current is very large. On average, the power of both states is large.
