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.
