Physics · Transducers and Strain Gauges
Four strain gauges are mounted on a simple flat tensile specimen arranged for complete temperature compensation and maximum sensitivity when connected in a four-arm bridge circuit. An 8 × 105 Ω calibration resistor is shunted across one of the strain gauges. If the gauge resistances are each 188 Ω and the gauge factors are 1.22, then the effective strain is:
