Precision Ultrasonic Frequency Measuring Instrument For Ultrasonic
Grinder
Description:
Impedance Analyzer is mainly used for piezoelectricity element impedance analysis and
parameter calculation. Before using piezoelectricity element, you
need to know its major parameters: resonance frequency Fs,
antiresonance frequency Fa, half point power F1 and F2, the max.
admittance Gmax, direct capacitance C0, dynamic resistance (R1, C1,
L1), free capacitance CT, free dielectric constant 33T,mechanical
quality factor Qm, electromechanical coupling factor Keff, plane
electromechanical coupling factor Kp and so on.

Functions:
This instrument can measure admittance characteristic curve of
piezoelectricity element (the admittance is equal to reciprocal of
impedance) and analyze and extractthe above needed parameters. With
this instrument, you can gain four characteristic curves of
piezoelectricity element (admittance characteristic graph,
impedancecharacteristic graph, admittance coordinate graph,
impedance coordinate graph).
Moreover, it is easy to save and print the measured result.
This instrument combines the hardware and PC software for impedance
analysis. The hardware system finishes impedance measure, and the
PC software finishes impedance analysis and parameter extraction
power.
This instrument is used for guiding piezoelectricity element's
testing and using.It is a synthetic solution of piezoelectricity
element's measurement and analysis.Moreover, it can evaluate and
test parameters of the piezoelectricity element.
Applications:
Impedance analyzer is widely applied in ultrasonic industries,including ultrasonic
plastic welder, ultrasonic cleaner, ultrasonic
transducer,ultrasonic electro machining, underwater acoustic
transducer, ultrasonic sensor, piezoelectric ceramic, parking
sensor, medical ultrasonic device, ultrasonic scaling device,
ultrasonic horn, ultrasonic welding head, ultrasonic grinder, and
ultrasonic emulsor.
Impedance analyzer is adopted to help the company make much profit,
1) Obviously improving product quality. Because the graphics of
impedance analyzer finds out whether there is unobvious bug inside
ultrasonic devices, it can be applied in testing Corp's materials
and instructing the production.
2) Rapid measurement speed can reduce human capital tremendously if
needful to measure a lot of devices.
3) Advantageous to the Corp's standardization production and
technical stabilization.
