Classification of piezoelectric wafers: P4 series with black wafers and P8 series with yellow wafers; B. Frequency classification: low frequency series (17 ~ 23KHz), intermediate frequency series (25 ~ 28KHz), medium and high frequency series (33 ~ 60KHz) and high frequency series (68-200KHz); C. Power classification: 30W series (including 35W), 50W series (including 60W), 100W series (including 80W) and other unconventional power; D. Shape classification: straight and horn type;Choice of frequency The frequency of the transducer is inversely proportional to the wavelength, and the size of the wavelength is related to the diameter of the cavities (strictly speaking, it is caused by low frequency and longer nucleation), and the diameter of the cavities is related to its explosion pressure. Generally, the higher the frequency, the smaller the wavelength, the smaller the diameter of the cavities, and the lower the explosion pressure, but the higher the density of the cavities and the better the permeability.based on the above principles: Low frequency (17 ~ 23KHz): When the dirt to be cleaned is heavy or difficult to clean, and the impact of the explosion on the surface of the cleaned material is not great, a low frequency transducer should be selected. Commonly used industries are: magnetic industry, auto maintenance industry, textile industry, etc. Note that this series is relatively noisy, so it is best to do sound insulation treatment. Intermediate frequency (25 ~ 28KHz): If the dirt to be cleaned is slightly heavy or difficult to clean, and the impact of the explosion on the surface of the cleaned material is not great, you should choose an intermediate frequency transducer. This series of industries is the most widely used. The common ones are: machining industry, electroplating industry, catering industry, etc. Medium and high frequency (33 ~ 60KHz): If the dirt to be cleaned is light, easy to clean, or if there is a requirement for the impact of the explosion on the surface of the cleaned object, a medium to high frequency transducer should be selected. Commonly used industries are: precision parts, glass glasses, electronic components, circuit boards, etc .; High frequency (68-200KHz): The dirt to be cleaned is very light and easy to clean. When it is required to prevent any damage to the surface of the cleaned object from the impact of explosion, a high frequency series transducer should be selected. Commonly used industries are: semiconductors, special high-precision parts, etc.Data in detail:TypeLength(mm)Weight(g)Frequency(KHz)Resonance Impedance(Ω)StaticCapacity(pF)±10%InputPower(W)OKSCTRANSDUCER28k100W666252810-205200100Payment terms:Prepaid by Bank/ Paypal/ Western union are acceptableShipping Indications:HKDHL: 3-7daysBEIJINGDHL: 3-5daysUPS:3-5daysFEDEX:1-5daysHKFEDEX:3-7daysEMS:7-15daysChinaair post (within 2Kg): 15-18daysChinaPost Air Paracel: 35-60days (above 2kg)
