Basics of Ultrasonic Cleaning

What is Ultrasonic Cleaning? When a varying or pulsating voltage is applied to a “Piezo Ceramic Transducer“ at a frequency higher than 20KHz (ultrasonic frequency range), it leads to contraction and expansion of the crystal. If these vibrating transducers are bonded to a metal tank’s bottom or side, the metal surface starts vibrating creating sonic Read More …
