Description

The BB strain gauge is a strain gauge designed with two strain gauges. The two strain gauges are oriented 90 degrees apart  (or in a TEE configuration) and are designed to work in tandem in Half-Bridge configuration. Multiple configurations are available to address different mounting configurations with three or four terminal outputs.

Features

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

Applications

  • Stress analysis
  • Transducer construction
