  • GF series: Low elastic modulus strain gauges

    The GF foil strain gauges are ideally suited for strain measurement on materials having low modulus of elasticity such as plastics. Designed with special grid pattern, these gauges exhibit reduced stiffening effect as well as the effect of Joule heat in the strain gauges. They are self-temperature compensated for materials having a thermal expansion coefficient of 50 or 70 x 10-6/oC.
    Operating temperature: -20oC - +80oC
    Applicable specimen: plastics
    Temp. compensation materials: plastics
    Temp. compensation range: +10oC - +80oC
    Strain limit: 30000 x 10-6 strain
