Information About

Gauge Factor




ε G = (ΔRB ÷ RB) = αθ

G = ÷ V × (1÷ε)

Where

G = Strain Gauge Factor

ε = strain

ΔRB = change in strain gauge resistance

RB = unstrained resistance of strain gauge

α = Temperature Coefficient

θ = temperature change

v = Voltmeter reading

V = circuit Potential Difference
