500kHz 1MHZ 3MHZ Graphic Transducer Pizeoceramic Tester Ultrasonic Frequency Impedance Analyzer

The application of impedance curves and admittance circles in the processing and production of ultrasonic devices is as follows:

● ultrasonic transducer: the admittance circle shall be free of parasitic circles, the resonant frequency shall be as close as possible to the design frequency, the dynamic impedance shall be low, the quality factor Qm shall be close to the design requirements, and the capacitance shall match the circuit.

Piezoelectric ceramic sheet: The device can be directly judged based on the admittance circle diagram and logarithmic coordinates. If there are layers or cracks inside the ceramic sheet, the logarithmic curve will have multiple peaks. Multiple parasitic small circles appear on the admittance circle diagram.

Ultrasonic horn and mold: Whether the design, processing, and assembly are reasonable or have defects can be clearly seen from the admittance circle diagram.

● ultrasonic welding machine: during production and processing, the results of admittance circle are used to analyze the state of the welding machine, and the existing problems of the welding machine are found through parameter and graphic analysis.

Ultrasonic cleaning machine: During production and processing, the selection of vibrators requires their vibration performance to be as consistent as possible (bandwidth, quality factor, resonance frequency, dynamic impedance). On the admittance circle diagram, there should be no parasitic circles as much as possible or no parasitic circles near the resonance point. The admittance circle can be used to analyze and measure the impedance characteristics of the manufacturing, incoming material inspection, bonded transducers, and cleaning machines of the transducer. The measurement of the entire cleaning machine can calibrate the resonance frequency and static capacitance of the machine to match the power supply. It can analyze the characteristics of its new resonance point, impedance after water injection, capacitance, and vibration mode of the entire machine.
