Description
Portable impedance analyzer is mainly used to measure the performance of ultrasonic transducers, ultrasonic horn Rod (unit), piezoelectric ceramics and high-frequency devices. It is one of the most convenient tools for impedance scanning and characteristic analysis of ultrasonic equipment. Wherever you go, you can quickly and conveniently test the parameters and characteristics of the devices and share them remotely.

For ultrasonic welding or processing, the Qm value of the
oscillator itself is generally about 500-1000, the whole system is
1500-3000, if too low, the vibration efficiency is low, but it can
not be too high, because the higher the Qm, the narrower the
working bandwidth, the power source is difficult to match, that is,
the power source is difficult to work at the resonance frequency
point, the equipment can not work.CT: The capacitance value of free
capacitor and piezoelectric device at 1 kHz is the same as that
measured by digital capacitance meter. By subtracting the dynamic
capacitance C1 from this value, the true static capacitance C0, C0
= CT-C1, can be obtained. The inductance should be used to
balancethe 20.In the circuit design of cleaning machine or
ultrasonic processing machine, balancing C0 correctly can improve
the power factor of power supply. There are two ways to use
inductance balance, parallel tuning and series tuning.
Fp: Anti-resonant frequency, the resonant frequency of parallel
branch of piezoelectric oscillator. At this frequency, the
impedance Zmax of piezoelectric oscillator is the largest. If the
anti-resonant impedance Zmax is very low, the oscillator has
problems.
Graphics
The impedance analyzer provides five kinds of coordinate charts, among which the logarithmic charts are of great significance for the detection of piezoelectric devices. The vibration performance of piezoelectric oscillator or vibration system can be judged directly by logarithmic coordinate diagram, which is more intuitive and practical.
