Part Number Breakdown

Description

The AA strain gauge is a strain gauge designed with for linear strain measurement. Its grid pattern is simple yet versatile and can be made to different lengths to best suit the application.

Features

  • Constantan grid material
  • Phenolic base material
  • Polyimide base material (Optional for High Temperature Environments)
  • Wire pre-bonded (Optional)

Applications

  • Stress analysis
  • Transducer construction
