Customer Reviews
The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

Latest company news about Ultrasonic impedance analyzer

Traditional ultrasonic impedance analyzer all need a computer running software to realize scanning analysis function, and HS520A provided by Altrasonic series ultrasonic impedance analyzer not only have the functions of the computer scanning analysis, also provide display in the instrument directly piezoelectric device scan function, customers no longer need a computer for each instrument configuration. This method not only ensures the test efficiency, but also reduces the test cost. This is HS520A series of products in the field of piezoelectric testing to provide customers with another super value solution.


At the same time, HS520A has good measurement accuracy, ultra-wide frequency range and excellent stability, which can meet the measurement requirements of most ultrasonic devices and materials.


Ultrasonic impedance analyzer is mainly used for the measurement of impedance characteristics of all kinds of ultrasonic devices, including: piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic ranging, ultrasonic motors, ultrasonic flowmeters, ultrasonic flaw detectors and other ultrasonic equipment.


Measurement parameter


For a piezoelectric device, its impedance characteristics vary with frequency. A complete description of a piezoelectric device requires an extremely complex circuit network, and a simpler network is selected in the frequency band we are interested in. (including inductors, resistors, capacitors), a more complete description of the characteristics of the piezoelectric device. It has been proved that the network is constructed by using the inductors, resistors and capacitors included in the following network, and the required network characteristics can be better reproduced.

For a general piezoelectric device, there is no other resonance in the frequency domain away from a certain resonant frequency. In the frequency domain near the resonant frequency, the device can be simulated with a plurality of inductors, resistors, and capacitors, and the corresponding equivalent circuit is as shown below. Shown as follows:
