About the BFRA Series for Composite Material Use
BF series composite strain gauge
These are foil strain gauges designed for measurement on composite materials. They have a specially designed grid pattern to enable small stiffening effect and excellent peformance in strain measurement up to 200°C. This series is available with self-temperature-compensation for a material having coefficient of thermal expansion of 3,5 or 8×10-6/°C. This series is recommended for use on ceramic, carbon and composite materials.
