Principle of Strain Gauge: Let us consider a conductor of length L and diameter D. This conductor is now stretched by force F as shown in figure below. As you can surmise, properly mounting a strain gauge is critical to its performance in ensuring that the applied strain of a material is accurately transferred through the adhesive and backing material, to the foil itself. The gauge factor is defined as: {\displaystyle GF= {\frac {\Delta R/R} {\Delta L/L}}= {\frac {\Delta R/R} {\varepsilon }}=1+2\nu + {\frac {\Delta \rho /\rho } {\varepsilon }}} The change of resistance is very small and it is usually measured using a Wheatstone bridge circuit where a strain gauge is connected into the circuit with a combination of four active gauges for full-bridge, two gauges for half-bridge or a single gauge for the quarter bridge. The complete strain state is composed of normal, shear, and principal strains. Gauge factor (GF) or strain factor of a strain gauge â¦ Online Books & Manuals Gage vs Gauge: Is there a difference?
