Impedance Analyzer For Ultrasonic Device

The proper frequency and impedance adjust is indispensable for all ultrasonic devices. The frequency depends mainly on dimensions (e.g.: length of the sonotrode) and the impedance of the quality of material used, assembly, and coupling of the acoustic sets’ parts. Deviations indicate the need for fine tuning, cleaning, re-gripping or re-assembly.

Description :

The HS-520A impedance analyzer can measure and evaluate the parameters and performance of various devices and devices such as piezoelectric ceramic sheets, piezoelectric transducers, and buzzers. Judging by the impedance-phase-frequency curve and the admittance circle, it is clear at a glance.

The impedance-phase-frequency curve and admittance circle of a normal product are shown in the following figure:


But not all of the device's graphics are as shown above. Here are the graphics for several problematic devices:
