GF Series
Plastic
This is a foil strain gage which is designed for the materials with low elastic modulus such as plastics, and is specially configured to minimize the effect of reinforcement effect resulted by gage installation. Self-temperature compensation is available for materials with thermal expansion of 50 and 70ppm/°C.
