Impedance analyzers can measure and evaluate to match the circuit
For piezoelectric ceramic sheets, the quality of the device can be directly judged from 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
Whether the design, processing, and assembly of the horn are reasonable or have defects can be clearly seen on the guide circle diagram
For the production and processing of ultrasonic welding machines, the results of the admittance circle are used to analyze the status of the welding machine. Through the analysis of parameters and graphics, problems with the welding machine are identified
For the 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 near the resonance point. It can be used for the manufacturing, incoming material inspection, and bonding of transducers The impedance characteristics of the cleaning machine can be analyzed and measured. The resonance frequency and static capacitance of the machine can be calibrated to match the power supply. The characteristics of its new resonance point, impedance after water injection, capacitance, and vibration mode of the entire machine can be analyzed
