<P>PROBLEM TO BE SOLVED: To provide a practicable ultrasonic intensity monitoring system in which the ultrasonic intensity of a cleaning tank is automatically monitored, when a given threshold value is come off, this event is determined promptly, the momentarily abnormality caused due to the change with the lapse of time of the washing performance and failure of an ultrasonic cleaning machine is detected, and high reliability control is achieved; and to provide an ultrasonic cleaning machine which includes the ultrasonic intensity monitoring system and has a cleaning performance of a high reliability. <P>SOLUTION: The ultrasonic intensity monitoring system for an ultrasonic cleaning machine includes: a transducer 4 that is provided at a cleaning tank 2, and converts an ultrasonic wave that propagates the cleaning tank 2 into an electrical signal; a regulator 5 that regulates the size of the electrical signal converted by the transducer 4; and a determination part 7 that determines whether the size of the electrical signal regulated by the regulator 5 is in a given range. The size of the electrical signal is one of a momentary voltage, a momentary current, a moving average or a simple average value of the electrical signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
