| May 10, 2018 at 22:25 | comment | added | Kono | By using two strain gauges in the bridge, the effect of temperature can be avoided. For example, Figure 5 illustrates a strain gauge configuration where one gauge is active (RG + ∆R), and a second gauge is placed transverse to the applied strain. Therefore, the strain has little effect on the second gauge, called the dummy gauge. However, any changes in temperature will affect both gauges in the same way. Because the temperature changes are identical in the two gauges, the ratio of their resistance does not change, the voltage VO does not change. | |

| May 10, 2018 at 21:43 | comment | added | Kono | It's said, that half or full bridge includes temperature compensation. This is half bridge. | |
| May 10, 2018 at 21:38 | comment | added | Marko Buršič | You would need also R1 and R2 to be strain gauges. | |
