The ZJ-3 piezoelectric tester (static pressure coefficient d33 measuring instrument) is a specialized instrument 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 model has added functions such as discharge protection, discharge prompt, and waveform output for the tested components, enabling the instrument to provide high-voltage discharge prompt and protection when measuring non discharged (especially large-sized) piezoelectric components. This instrument is an essential tool for the production, application, and research departments of piezoelectric materials and components.
