The innovators who, in 1988, brought you the concept of SWEEP frequency extend the state of the art with patented dualSWEEP and now upSWEEP technology. The concept of dualSWEEP, an improvement to the conventional fixed fre- quency sweep rate, is the introduction into the tank of a non- constant sweep. This is accomplished by linearly sweeping the sweep rate. When a typical Langevin-type transducer is swept through a bandwidth of frequencies, the output power is not constant for each frequency. Generally, the output power of a sharp resonance transducer peaks near the center of the bandwidth. When sweeping up in frequency, a peak pulse of power is put into the tank at the center of the sweep range; when sweeping down in frequency, another peak pulse of power is put into the tank at the center of this sweep range.This process continues, producing equally spaced power pulses at a rate equal to two times the sweep rate. The resonance phenomena is caused by repeatedly pumping energy into a part at its resonant frequency. A non-constant sweep rate will vary the spacing between the power pulses, avoiding a resonant condition and potential damage.

multiSONIK: The next revolutionary step in ultrasonic cleaning technology. For the first time a system that allows operation at constant power at multiple distinct frequencies. Blackstone~NEY Ultrasonics has continuously focused on the entire ultrasonic cleaning process, not just the transducer or generator in isolation. It is this holistic approach that drives all of our engineering efforts, demonstrated in the major performance factors of frequency modulation, amplitude modulation and transducer design and, now, multiple frequencies from a single generator/transducer combination. Frequency Modulation

Conventional ultrasonic power delivery to a cleaning fluid. Conventional sweep results in periodic pulses that can excite a part into damaging resonance.

Our patented dualSWEEP technology, coupled with the broadband universal transducer, protects parts from damaging resonances by delivering power evenly and non-periodically.
