| Summary | Ultrasonic vibrators (can be called other names such as Transducer and Condenser) made by using piezoelectric ceramics are an assembly of using a piezoelectric phenomenon that can convert electrical energy into mechanical energy by the resonance phenomenon of the piezoelectric ceramics. |
| Division | Bolt-clamped Langevin Transducer: BLT, which has a different style according to manufacturing methods and now has a stable structure, is used the most. It may be divided into 28 kHz, 40 kHz, 50 kHz, 60 kHz, and etc. depending on the resonance frequency. |
| Types | It is variously divided into 28 kHz, 40 kHz, 50 kHz, 60 kHz, 80 kHz, 100 kHz, 135 kHz and 170 kHz according to the type of material to be cleaned. |
| Features | It uses a vibrator with a difference resonance frequency depending on the type of material to be cleaned. It applies either frequency or output depending on the completion of cleaning contaminants. |
