Averaging Axial Extensometer

This Averaging Axial Extensometer (Series 632.17) is designed to simultaneously measure the axial deflection on opposite sides of the specimen. This extensometer is typically used to perform testing on solid or tubular composite or metal specimens.

Key Features & Benefits

  • Simultaneously Measures Axial Deflection — Simultaneously measures axial deflection on opposite sides of the specimen to reduce measurement errors caused by specimen bending
  • Patented Support System — Securely attaches the extensometer to the specimen while providing the necessary freedom of movement
  • Cross-Flexure Design — Ensures true center-point bending throughout the entire travel range of the extensometer
  • Innovative Contact Assemblies — Accommodates specimen bending or twisting without slippage or output distortion, increasing accuracy
