Impedance analyzer is a digital impedance analyzer and precision LCR meter that sets the new standard for impedance measurements in the frequency range from 1KHz‾5MHz (extended to 5 MHz when upgraded).
The impedance measurement of a piezoelectric device is a prerequisite for the correct use of the device. For a piezoelectric device, its main parameters can be obtained through an impedance analyzer, including: resonance frequency Fs, anti-resonance frequency Fp, half power points F1 and F2, maximum admittance Gmax, static capacitance C0, dynamic reactance R1, dynamic capacitance C1, Dynamic inductance L1, free capacitance CT, free dielectric constant, mechanical quality factor Qm, electromechanical coupling coefficients Keff, Kp, K31, K33, etc., and can draw five kinds of characteristic curves (admittance characteristic diagram, impedance characteristic diagram) of piezoelectric devices , Admittance polar diagram, impedance polar diagram, logarithmic diagram).
Ultrasonic Component Analyzer PV520A A comprehensive solution for the inspection of piezoelectric ultrasonic devices and equipment.
PV520A is a new generation of portable touch screen analyzer.
Its characteristics are as follows:
1. Dimensions are only 24cm * 14cm * (front 5cm and back 10cm) and weigh only 1.95 kg.
The world's most portable ultrasonic impedance analyzer.
2. Large touch screen, no physical keys required, all parameters and graphics are displayed at once, more intuitive.
3. Super fast test speed, it only takes 5 seconds to test 1000 points at a time.
4. It can also be connected to a computer, and the software is fully compatible with PV70A / 80A.
5. The maximum test frequency can reach 5MHz.
The system provides a dozen parameters, the average user is commonly used the following parameters:
Fs: mechanical resonant frequency, that is the operating frequency of the vibration system, the design should be as close to the expected value, and must match the power supply point.
R1: dynamic resistance, the piezoelectric vibrator series branch resistor, the internal resistance of the device is, the greater the resistance, the higher the power loss of energy.
Qm: mechanical quality factor, Qm, the higher electro-acoustic transducer conversion efficiency, but also the more narrow bandwidth transducer, generally moderate better.
CT: freedom capacitors, piezoelectric device capacitance value at 1kHz frequency, this value is subtracted dynamic capacitance C1 can get real capacitanceC0.
Fp: anti-resonance frequency, the piezoelectric oscillator resonant frequency of parallel branches.
Application: all kinds of ultrasound parts testing: piezoelectric ceramic, transducer, ultrasonic cleaner,
ultrasonic plastic welding machine, water sound, magnetostrictive material, ultrasonic disintegrator,
ultrasonic atomizing, ultrasonic tooth cleaner, distance sensor,ultrasonic emulsification, ultrasonic descaling,
ultrasonic motor, and all other piezoelectric and ultrasonic equipment and device.
