Intelligent Manufacturing ZJ-4 Precision d33 Coefficient Measuring Instrument

The Institute of Acoustics, Chinese Academy of Sciences solemnly declares:

1. Material product measurement, data is authentic and reliable. Please do not trust any other products that replicate our parameters

2. There are units online impersonating our piezoelectric products and piezoelectric polarization devices, using stolen images and technical parameters. Our products have not been authorized to any unit, and we confirm that the products can be directly:.

3. In order to protect the interests of buyers: we support payment after the goods are received and inspected.

At present, our country attaches increasing importance to material testing, and many units and research institutions have encountered significant problems in product identification. However, to truly test materials, it is necessary to choose a reliable testing product, which will have a great impact on one's own testing results and research,The guiding role it brings to our production.

ZJ-4 piezoelectric tester (static pressure coefficient d33 measuring instrument)
Keywords: piezoelectric, ceramic materials, polymers, d33/d15

1、 Product Introduction:

The ZJ-4 piezoelectric tester (static pressure coefficient d33 measuring instrument) is designed to measure the d33 constant of piezoelectric materials. It can be used to measure piezoelectric ceramics with large piezoelectric constants, piezoelectric single crystals with small piezoelectric constants, and piezoelectric polymer materials. In addition, it can also measure the equivalent piezoelectric d'33 constant of any oriented piezoelectric single crystal and certain piezoelectric devices. The instrument has a wide measurement range, fine resolution, high reliability, simple operation, and no special requirements for sample size and shape. Circular discs, rings, tubes, blocks, strips, columns, and hemispherical shells can be measured, and the measurement results and polarity are directly displayed on a three and a half digit panel meter. The ZJ-3 piezoelectric tester (static pressure coefficient d33 measuring instrument) adds functions such as discharge protection, discharge prompt, and waveform output to the original ZJ-3 piezoelectric tester, enabling the instrument to provide high-voltage discharge prompt and protection when measuring undischarged (especially large-sized) piezoelectric components,
