1️⃣ Misconception 1: "Higher Power Always Means Better Results"
While increasing ultrasonic power may seem beneficial, excessive power can damage sensitive materials-such as precision components, glass, or biological samples-and shorten the lifespan of the transducer system.
💡 Best Practice:
Always identify the material's tolerance threshold first. Use medium or low power for delicate materials and pair it with an appropriate frequency rather than maximizing output.
2️⃣ Misconception 2: "Power and Frequency Are Independent"
Power and frequency are closely related.
High-frequency systems concentrate energy in smaller regions, increasing the risk of localized heating.
Low-frequency systems spread energy over a larger area but may lack intensity for certain processes.
💡 Best Practice:
Select the frequency based on your target application (cleaning, bonding, dispersion, etc.), and then set power accordingly. For example, <2 kW is suitable for high-frequency systems, while >5 kW often fits low-frequency operations.
3️⃣ Misconception 3: "Ignoring the Effective Working Area"
For the same power level, high-frequency ultrasonic systems typically produce a smaller effective working area.
If that area is too small, the local energy density becomes too high-leading to uneven cleaning, lower efficiency, or even damage.
💡 Best Practice:
When treating large surfaces, use low-frequency or higher-power systems, or consider multi-transducer configurations to expand the effective area.
Conclusion
Achieving the best ultrasonic performance is not about maximizing power-it's about balancing power, frequency, and working area.
A scientific approach ensures higher efficiency, consistent results, and longer equipment life.
