There are various achievements in the field of micro-nanotribology! The minimum resolution is 5μN.

This product is a sensor that can measure micro forces with high resolution using a strain gauge and a capacitive displacement meter. It has a dynamic range of 80 dB and is compact and lightweight. The minimum resolution is 5 μN. Additionally, depending on the mounting direction of the sensor probe, it can measure small forces in either compression, tension, or both. 【Features】 ■ Main sensor component of the micro-nano tribology series friction and wear testing machine ■ High-resolution micro force measurement using a strain gauge and a capacitive displacement meter ■ Capable of measuring small forces in compression, tension, or both depending on the sensor probe mounting direction ■ Available for sale as a standalone sensor (capacitive displacement meter required) ■ Proven track record in various applications in the micro-nano tribology field *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Detection Method】 ■ The displacement of the leaf spring is captured as a change in capacitance by the sensor probe. ■ A special holding mechanism is provided between the leaf spring and the sensor probe to adjust the minute gap during installation. ■ The displacement caused by external forces on the strain gauge is proportional to the strength of the external force within the elastic limit; therefore, the displacement is measured with a capacitance displacement meter, and stoppers are placed before and after the strain gauge to indirectly measure the external force, preventing damage to the sensor. ■ There is also freedom in the measurement direction, allowing for measurements in various orientations such as horizontal and vertical. *For more details, please refer to the PDF document or feel free to contact us.
