Ultrasonic Impedance Analyzer Test Ultrasonic 1-500kHz Transducer Converter Frequency Impedance

Impedance tester application:

Transducers: The admittance circle diagram should not show parasitic circles, the resonant frequency should be as close as possible to the design frequency, the dynamic impedance should be low, the quality factor Qm should be close to the design requirements, and the capacitance should 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, and multiple parasitic small circles will appear on the admittance circle diagram.

The design, processing, and assembly of the horn are reasonable or have defects, which can be clearly seen on the guide circle diagram. For the production and processing of ultrasonic welding machine, the results of admittance circle are used to analyze the state of the welding machine. Through the analysis of parameters and graphics, the existing problems of the welding machine are found.

Production and processing of ultrasonic cleaning machines: 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. Impedance characteristic analysis and measurement can be conducted on the manufacturing of transducers, incoming material inspection, bonded transducers, and cleaning machines. 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.
