Static strain gauge is used for multi-point static strain measurement. It has the advantages of good stability, small drift and strong anti-interference ability. Strain, DC voltage/current, thermocouple and other sensors, suitable for long-distance transmission, reserved wireless test function. The bridge form of each measuring point is relatively independent, with a variety of compensation forms, can be connected to the computer through RS232/USB interface, real-time test data display. It is widely used in engineering survey and teaching, fatigue test and strain structure test.
