Strain gaging in 10 easy steps!

In a recent blog post, StrainBlogTM presents 10 steps as a guide to successfully installing strain gages.

These steps are summarized below:

1. Determine the operating (i.e. testing) temperature. This will determine the foil strain sensor series, the adhesive and protection during the sensor selection process as well as the lead wire and solder.
2. Define the anticipated elongation. Foil strain sensor types and bonding adhesives have different elongation capabilities.
3. Define the number of loading cycles. This means selecting the correct type of sensing foil and configuration for the sensor which is compatible with the required strain strain level and number of loading cycles.
4. Select the correct gage STC number. This is determined using the type of test material.
5. Select the active gage length.
6. Select the pattern type. This is based on the type of measurement you are conducting.
7. Select the correct resistance required for the application.
8. Select any additional options such as integral lead wires or terminals. These additions can simplify the foil sensor installation or wiring.
9. Perform an electrical check to confirm that the gage is wired correctly with the appropriate resistance.
10. Lastly – select and apply a gage protection system based on the operating environment and duration of test.
