The 28KHZ/40KHZ ultrasonic oscillator transducer is a device used in ultrasonic processing equipment to convert electrical energy at ultrasonic frequencies into ultrasonic energy. The equivalent impedance analysis method of the circuit explains that the working characteristics of the transducer, the impedance characteristics of the transducer, and the working mode of the sensor are closely related to the assembly structure of the transducer itself and the material characteristics of the transducer components. The impedance characteristics of the transducer must match the impedance of the transmission circuit of the device to achieve resonance transmission characteristics.
