Abstract
An ultrasonic cleaning system that includes an electrical power supply, and a plurality of ultrasonic transducers coupled in parallel, wherein the plurality of ultrasonic transducers are coupled to the electrical power supply. The ultrasonic cleaning system also includes a transducer fault indicator coupled between the electrical power supply and the plurality of ultrasonic transducers, wherein the transducer fault indicator consists essentially of a current sensing portion configured to detect electrical current, and an alarm mechanism coupled to the current sensing portion. Additionally, the alarm mechanism is configured to provide a signal, indicating a failure of the ultrasonic transducer, based on the magnitude of electrical current detected by the current sensing portion.
