The "Load Tester" is a pressure display device for d33 meters with a measurement range of 0.01 to 9.99N (resolution: 0.01N). Compared to ceramics, it is softer and undergoes elastic deformation, which affects the d33 value. Therefore, to ensure a constant load is applied, the piezoelectric materials (such as resin and thin film substrates) can monitor and adjust the applied load based on the load applied. By attaching this device to the d33 meter body, it monitors the pressure directly applied to the specimen. 【Features】 ■ Softer and undergoes elastic deformation compared to ceramics, affecting the d33 value ■ Attaches to the d33 meter body to monitor the pressure directly applied to the specimen *For more details, please refer to the PDF document or feel free to contact us.

Piezoelectric materials are functional materials that expand and contract when a voltage is applied, and they are widely used in actuators and various sensors. In recent years, these piezoelectric devices have expanded from traditional ceramics to applications using resin films and thin-film substrates due to the miniaturization and increased sensitivity of the equipment they are mounted on. Our company is advancing the proposal of various piezoelectric evaluation methods tailored to customer needs and the development of various measurement instruments based on the evaluation technology cultivated with traditional ceramics, in response to the diversification of these materials and devices.

The "Piezo reader" is a device for measuring the piezoelectric constants (d33, d31) of piezoelectric materials. Materials with low piezoelectric constants can also be measured by switching the measurement range. Furthermore, for soft piezoelectric resins and thin film materials, measurements are taken with controlled low loads to minimize large elastic deformations. Additionally, with dedicated software, measurement conditions (applied load, application time, etc.) can be input from a computer, and the measurement results can be displayed on the computer screen. 【Features】 ■ Measures the piezoelectric constants of piezoelectric materials, connects to a computer, allows input of measurement conditions via dedicated software, and enables graphical display of measurement results and data storage. ■ Materials with low piezoelectric constants can also be measured by switching the measurement range. ■ Measurements can be taken for soft materials with controlled low loads. *For more details, please refer to the catalog or feel free to contact us.
