The strain gage is one of the most important tools of the electrical measurement technique applied to the measurement of mechanical quantities. As their name indicates, they are used for the measurement of strain.
Strain gages have endless uses in structural test and monitoring applications. Are you getting the most signal out of your strain amplifier? In this blog, we share eight tips to help you choose the right strain gage amplifier for your data acquisition system.
For which applications can strain gage measurements be used?
Strain gage technology has practically unlimited uses in structural test and monitoring applications, like durability testing of structural components in the automotive and rolling stock industry. The use of strain gage technology in aviation, military, and space applications has a long history. Strain gages are bonded directly to structural load-bearing components for static and fatigue testing of components and sub-assemblies. In the renewable wind energy industry, strain gage technology is applied to test the structural performance of wind turbine blades and bearings and structural health monitoring of wind turbines in the field. Strain gages may also be used to monitor civil engineering structures (bridges, tunnels, railways, dams), oil and gas pipelines, or nuclear plants.
