Overview

Sensors based on the strain principle are widely used in industry, scientific research, military and other fields. As the degree of industrial automation becomes higher and higher, the automation control response is more real-time, the edge calculation requires more data, and the requirements for testing are further upgraded from qualitative testing to quantitative testing. In new energy, automotive assembly and manufacturing, industrial robotics, intelligent transportation, civil engineering and the Internet of Things and other fields, the traditional static or low-speed acquisition is difficult to match the needs of the East to dynamic measurement. t070B four-channel distributed response acquisition card in providing measurement accuracy based on the traditional force measurement response frequency from 100Hz to 10kHz.
