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.

Main Test Materials Plastics Materials Backing Epoxy
Operating Temperature -20 to +80°C Materials Element Cu-Ni alloy foil
Compensation range +10 to +80°C Strain limit 3%
(30000×10-6)
Bonding adhesive CN Fatigue life at room temp. 1×106
(±1500×10-6)
