Description

The EB strain gauge is a special strain gauge that incorporates 4 individual strain gauges oriented 90° apart and configured in a full bridge configuration. The full bridge configuration means the strain gauges are pre-wired internally so no additional connections are required. Only 4 terminals are available: 2 for input and 2 for output making it easy to install. Wiring options are available to accommodate different applications.

 

Features

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

Applications

  • Stress analysis
  • Transducer construction
