Sir Armand Augustin Fondjo

Follow this helpful link

https://www.kyowa-ei.com/eng/technical/strain_gages/selection_chart.html

Anis Hamza

The installation and operating characteristics of a strain gage are affected by the following parameters, which are selectable in varying degrees:

• Strain-sensitive alloy

• Backing material (carrier)

• Grid resistance

• Gage pattern

• Self-temperature compensation number

• Gage length

• Options
