  • QF Series: High temperature strain gauges

    The QF series is a foil strain gauge with polyimide resin backing designed for high temperature application. It is capable of generating stable and accurate measurement in environment with temperature up to 200oC. Other than general strain measurement, the QF series can also be used for stress concentration, torque and shearing strain measurement.
    Operating temperature: -20oC - +200oC
    Applicable specimen: Metal, Ceramic
    Temp. compensation materials: Mild Steel, Stainless Steel, Aluminum, Magnesium
    Temp. compensation range: +10oC - +100oC
    Strain limit: 30000 x 10-6 strain
