The significant advantage of ultrasonic cleaning technique is the abilities to clean the delicate and complex shape materials without damaging their surfaces quickly. Ultrasonic cleaners have found increasing applications in a variety of industries because these offer an environmentally good alternative to ozone-depleting compounds and hazardous solvents. Also, ultrasonic vibration is one of the methods for chemical synthesis (chemical reaction) and of yield enhancement of chemical engineering process. Consequently, there is a need to develop multipurpose ultrasonic cleaner/vibrator using computer control, which can be used to set the various performance parameter of ultrasonic vibrator such as frequency, duty cycle, continuous/pulsed mode, duration of operation, and thermal profile of tank during the process. An ultrasonic cleaner was developed using an oscillator circuit and the duration of oscillator circuit functioning can be set through the computer. Computerised ultrasonic cleaner using indigenously made piezoceramic transducers and their advantages over the conventional ultrasonic cleaners are discussed.
