Ultrasonic element analyzer PV520A series can work in any voltage of AC220V-250V, power is 30W, the instrument comes with a special power supply, power supply socket is in the back of the instrument (the 5-core aviation plug).
For piezoelectric devices, the main parameters obtained by impedance analyzer include: Resonant frequency Fs, anti-resonant frequency Fp, half-power point F1 and F2, maximum admittance Gmax, electrostatic capacity C0, dynamic reactance R1, dynamic capacitance C1, dynamic inductance L1, free capacitance CT, free dielectric constant, mechanical quality factor Qm, electromechanical coupling coefficient Keff, Kp, K31, K33, etc.
Features:
Impedance analyzer is mainly used for the detection of piezoelectric devices (such as a single piezoelectric ceramic plate, or a single transducer, or transducer + amplitude modulator/welding head). Through the impedance analyzer, we can get some technical indicators that can not be seen directly, but have an important impact on product quality, which can guide production. Impedance analyzer, as the name implies, is to test the impedance characteristics of all kinds of piezoelectric devices, suitable for the development and production of all kinds of ultrasonic equipment.
