Define gauge factor of a strain gauge

WebThe photoelectric gauge uses a light beam, two fine gratings, and a photocell detector to generate an electrical current that is proportional to strain. The gauge length of these devices can be as short as 1/16 inch, but they are costly and delicate. The first bonded, metallic wire-type strain gauge was developed in 1938. Web4. Think of this (bridge) circuit as two simple potential dividers. R3 and R4 divide the excitation voltage in the ratio. V1 = R4/ (R3 +R4) * E. R2 an R1 divide the excitation voltage in the ratio. V2 = R1/ (R2 + R1) *E. The output voltage, e, is the difference between V1 and V2 (assuming no current is taken by the measuring equipment) Share.

Web0. My understanding is that strain gauges are constructed using constantan etched onto a flex PCB. According to wikipedia, constantan is a highly suitable strain gauge material due to its high gauge factor. I recently came across this document which shows that copper has a higher gauge factor (2.6 compared to 2.1) than constantan.
