  • Measurement Type Strain
OMEGA™ uni-axial strain gages are available in a variety of models to cover most strain measurement applications. Their rugged construction and flexibility make them suitable for highly accurate static and dynamic measurement. The measuring grid is formed by etching constantan foil, which is then completely sealed in a carrier medium composed of polyimide film.

Rated 3 out of 5 by from They work, but with some installation issues These strain gauges work reasonably well, but with lower mechanical gain than some other brands. Their solder pads are actually quite difficult to solder to, and multiple calls to their technical help line went unanswered.

Rated 5 out of 5 by from great for student use ribbon leads are perfect for student labs - no need to solder, and no long lengths of wire hanging on the parts. Pug alligator clipped leads on the DAQ, and ready to roll.

Rated 5 out of 5 by from SGD-1.5/120-LY11 Review Gauges arrived on time, as I had to expedite shipping. They work excellent as expected from Omega products. I am a student working on an engineering project and applied the gauges to aluminum and interfaced with an Arduino to collect strain measurements under varying loads. Would recommend if you're looking for a small/medium strain gauge that is easy to apply to most materials.

We received a package of SGD-10/350-LY13. I was wondering what is CHT: 317 mean? cannot find any information on it. Also, our application requires temperature compensation, where can I find information on temperature sensitivity of the gauge factor?

The description and item number dont match

Asked by: JBOB
JBOB, the SGD-3/350-LY11 stands for 3 mm grid, the 350 stands for 350 ohm and the LY stands for Linear. The description is incorrectly marked as 120 ohm. Please go with description on the spec sheet
