About the GFRA Series for Plastic Use
GF series low elastic strain gauge
These gauges are suited for the measurement on materials such as plastics, which have low elastic modulus compared to metal. These specially designed grid reduces the stiffening effect of the strain gauges to the specimen material, and also reduces the effect of Joule heat in the strain gauges. This series is available with self-temperature-compensation for the material having a coefficient of thermal expansion of 50 or 70×10-6/°C.
