What is Gage Factor mean?
Gauge factor (GF) or strain factor of a strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. The gauge factor is defined as:
G F = Δ R / R Δ L / L = Δ R / R ε = 1 + 2 ν + Δ ρ / ρ ε {\displaystyle GF={\frac {\Delta R/R}{\Delta L/L}}={\frac {\Delta R/R}{\varepsilon }}=1+2\nu +{\frac {\Delta \rho /\rho }{\varepsilon }}}where
ε = strain = Δ L / L 0 {\displaystyle \Delta L/L_{0}} Δ L {\displaystyle \Delta L} = absolute change in length L 0 {\displaystyle L_{0}} = original lengthν = Poisson's ratioρ = resistivityΔR = change in strain gauge resistance due axial strain and lateral strainR = unstrained resistance of strain gauge referencePosted on 05 Nov 2024, this text provides information on Miscellaneous in Space Science related to Space Science.
