This ultrasonic transducer is used for ultrasonic washing and cleaning machine.
In the modern city, more and more family use the ultrasonic dish-washing machine. It can degradation the fruit pesticide and sterilization.
Transducer adopts different piezoelectric material description:
Black chips for the P4 series, this kind of piezoelectric materials belong to medium power emission type materials, has a dual characteristic to send and receive,
Has taught low dielectric loss and high mechanical quality factor, the main application Yu Chaosheng cleaning, ultrasonic atomizer, etc.
Yellow chips for the P8 series, this kind of piezoelectric material belongs to large power emission type, the main characteristics of high mechanical quality factor,
Good stability, very low dielectric loss, especially suitable for the production of high power transmission with ultrasonic transducer.Widely used in
Ultrasonic welding, ultrasonic emulsification, ultrasonic polishing, ultrasonic cleaning, etc.
The comparison of different wafer transducer:
1).Yellow chip assembly transducer capacitance change absolute value is low, small loss at high field, thus relative to the same driver circuit, low calorific value and good thermal stability.Spray characterized by stability to washing load change, impact, the quadrature in the compasses type.
2).Black wafer transducer high electromechanical coupling coefficient, high Curie temperature, and high electroacoustic converting efficiency. And than other general P4 series products have higher stability and high heat resistance.Spray of water column, high cavitation feel is rich, but high sensitivity to wash load change.
3) use occasions (recommended) : high frequency (such as more than 40 k) or low power transducer (below 60 w) use black chip assembly
Transducer, low frequency or high power transducer using yellow chip assembly.

Ultrasonic Transducer also called ultrasonic Oscillator, if used in washing area, we call it ultrasonic cleaning transducer.
Ultrasonic cleaning by ultrasonic vibration produced by the transducer, in the water produced by cavitation effect of instantaneous high pressure cavity, the impact is clean and good cleaning effect.
