  • F Series: General Use Foil Strain Gauges

    The F series general foil strain gauges use Cu-Ni alloy foils for the grid and epoxy resin for the backing. The epoxy resin backing is color-coded to identify materials for self-temperature compensation. Special versions of these gauges are also available for measurement of shearing strain, residual stress, torque, stress concentration and strain measurement on glass or ceramic.
    Operating temperature: -196oC - +150oC
    Applicable specimen: Metal, glass, ceramic
    Temp. compensation materials: Mild Steel, Stainless Steel, Aluminum, Ceramic, Glass
    Temp. compensation range: +10oC - +100oC
    Strain limit: 50000 x 10-6 strain
