How can you tell if your ultrasonic cleaner is working right? There is no universally accepted standard for evaluating the performance of an ultrasonic cleaner. Several methods are available which will detect day to day variations in relative ultrasonic intensity. The classic "aluminum foil test," removing graphite from a ceramic surface and various hydrophone-type devices are the most commonly used for this purpose. When using any of these, it is important to duplicate conditions as closely as possible to assure that any change indicates a true variation in the ultrasonic performance and is not related to a change in temperature, soil loading, chemical concentration or any of several other variables. For critical applications and where the expertise is available, an alternative approach is to evaluate the transducer condition by measuring its capacitance and resistance and to monitor the generator power by measuring its input current, input power or output power. If the transducer characteristics are within specifications and if the generator is drawing the correct power from the AC lines or delivering the correct power to the transducers, the probability that the ultrasonic cleaner is working right is very high.
