DescriptionOMEGA™ stress relief strain gage roesttes are available in a variety of different models to cover most strain measurement applications. The rugged construction and flexibility make these general purpose strain gages ideal for residual stress analysis with a high degree of accuracy. The measuring grid is formed by etching Constantan foil, which is then completely sealed in a carrier medium composed of polyimide film. Either ribbon leads or solder pad termination style strain gages are available. Standard strain gages have temperature coefficients matched to either steel of aluminum.
