At 7:00 the strain is what is actually experienced by the test object at the location where the strain gauge is mounted. More: community.sw.siemens.com/s/article/Introduction-to-Strain-Gauges
@@SimcenterTesting Strain sensors are ratiometric. Most sensors output a voltage that is proportional to an engineering quantity (e.g. mV/g for an accelerometer). A strain gauge outputs a voltage ratio (Vout/Vsupply) that is proportional to strain (mV/V/Eue). Do you have an example for this? In other words how can I calculate a sensitivity so my instrumentation can output the correct microstrain output?
@@michaelc1063 Try looking at the example in Section 7 of this article (it does show V/V, but you can convert to mV/V): community.sw.siemens.com/s/article/Introduction-to-Strain-Gauges. If you are a user of Simcenter Testlab, the software supports ratio-metric sensors: community.sw.siemens.com/s/article/how-to-measure-strain-gauges-with-simcenter-testlab
The best lecture I've seen on this. Thanks 3000
