FB

Part Number Breakdown

Description

The FB strain gauge is a strain gauge designed with two strain gauges. Unlike the BB strain gauge series, the FB strain gauges are parallel and are oriented in the same axis. Options are available for three or four terminal output.

 

Features

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

Applications

  • Stress analysis
  • Transducer construction
