Overview
FM+AM oscillation system reduces cleaning irregularities and saves energy
Special feature
●FM (frequency modulation) + AM (output modulation).
Highly efficient energy-saving type with reduced cleaning irregularities.
●The generator is 1/3 the size and weight of conventional models – in our comparisom.
●No adjustment of the generator is required when replacing the transducer unit, making maintenance easy.
FM+AM oscillation method
FM modulation refers to continuously varying the frequency of ultrasonic waves, and AM modulation refers to varying the output. This FM+AM oscillation makes the ultrasonic waves in the tank uniform, reducing unevenness in cleaning and providing stable performance against load fluctuation from workpiece, liquid type and liquid depth.
