Ultrasonic impedance analyzer for sonotrode tuning and transducer testing

Principle:

The impedance analyzer can be measured and evaluated to match the circuit. For piezoelectric ceramics, you can directly judge the advantages and disadvantages of the device based on the admittance circle diagram and the logarithmic coordinates. If the ceramic chip is layered or cracked, the logarithmic curve will have multiple peaks and the admittance circle diagram will have multiple small circles.

Whether the horn is properly designed, machined and assembled, or defective, can be seen directly on the guide circle.
