Impedance analyzer 1-500khz for measuring transducer parameters
The application of impedance curve and admittance circle in the processing and production of supersonic components is as follows:
Transducer: Admittance circle should not appear parasitic circle, resonance frequency should be as close as possible to the design frequency, dynamic impedance should be low, quality factor Qm should be close to the design requirements, capacitance should match the circuit.
Piezoelectric Ceramic Sheet: It can judge the quality of the device directly from the admittance circle diagram and logarithmic coordinates. If there are layers or cracks in the ceramic sheet, the logarithmic curve will have multiple peaks. Several parasitic circles appear on the admittance circle.
Amplifier: Whether the design, processing and assembly are reasonable or defective can be clearly seen from the admittance circle chart.
Ultrasound welding machine: In production and processing, the state of the welding machine is analyzed by the result of admittance circle, and the problems of the welding machine are found through the analysis of parameters and graphics.
