  • BF series: Strain gauges for composites

    The BF foil strain gauges are developed for strain measurement on composite materials. Similar with UBF strain gauges, the BF gauges have specially designed grid pattern and newly developed gauge backing to deliver significant improvements in terms of reducing the stiffening effect and creep characteristics compared to conventional strain gauges. These gauges are self-temperature compensated for materials having thermal expansion coefficient of 3, 5 or 8 x 10-6/oC.
    Operating temperature: -20oC - +200oC
    Applicable specimen: Ceramic, carbon, composite
    Temp. compensation materials: composite
    Temp. compensation range: +10oC - +80oC
    Strain limit: 30000 x 10-6 strain
