초음파 변환기,초음파 발생기,초음파 세척기 - SKSONIC
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.
