Foil Strain Gages for Composite Materials

These strain gages are suitable for measuring strain in compound materials such as CFRP and GFRP. They make use of a special pattern to improve the effect of self heating caused by gage current as well as the reinforcement effect on low-elastic materials. *To ensure accurate measurement by avoiding the self-heating effect of gage current, consider the following: 1. Select a lower excitation voltage on a measuring instrument. 2. Active-dummy system 3. 350 Ω strain gages
