How to choose the frequency of ultrasonic transducer
Frequency Selection
Transducer frequencies are opposite to wavelength. Wavelengths are associated with the diameter of bubbles (strictly speaking, because the nuclear formation is less frequent), and explosion pressure associated with the bubble diameter. Generally, the higher the frequency, the smaller the wavelength, the smaller the diameter of the bubble and the lower explosion pressure, but the better foam density and permeability.
Based on the above principle:
Low Frequency (17-23kHz): You need to choose a low frequency series transducer that is not heavy and difficult to clean, and the impact of explosion on the surface of the object being cleaned. Commonly used industries are magnetic industry, automotive industry, textile industry, etc. This series is noisy and most soundproofing.
Medium Frequency (25-28kHz): You need to choose a Medium Frequency Series transducer that is slightly heavier and difficult to clean and not affected by explosion on the surface of the object being cleaned. This series of industries is the most widely used and common: machinery industry, electroplating industry, catering industry, etc.
Medium High Frequency (33-60kHz): When the dirt to be purified, easy to clean, or if there is an effect of explosion, you should choose a medium series transducer. Required for surfaces that are subject to washing. Commonly used industries include precision components, glass glasses, electronic components, circuit boards and more.
High Frequency (68-200kHz): The dirt being cleaned is very light and easy to clean. If you need to prevent damage to the surface of the object from being exploded by cleaning, you should choose a high frequency series transducer. Commonly used industries include semiconductors, special precision components.
