Hualanhai foil resistance strain gauge is mainly composed of substrate, sensitive grid, adhesive and protective layer. It is etched by metal foil with thickness of 0.005mm. The sensitive grid is very thin and can better reflect the deformation of component surface. Therefore, the measurement accuracy is high. 60-5000 ohm strain gauge can be customized; It is widely used in various weighing instruments, industrial force measurement, stress analysis and testing, high temperature melt pressure sensors and so on.
