A load cell has four identical strain gauges with an unstrained resistance
A load cell has four identical strain gauges with an unstrained resistance of 120.000 Ω for each gauge (a standard value). When a load is added, the gauges in tension increase their resistance by 60 m Ω to 120.060 Ω and the gauges in compression decrease their resistance by 60 m Ω to 119.940 Ω as shown in Figure 81. What is the output voltage under load?
