MODEL 3550 Axial/Torsional Extensometers
Designed for simultaneously measuring axial and torsional deflections on specimens tested in axial/torsional machines.
MODEL 3550HT High Temperature Axial/Torsional Extensometers
Designed for simultaneously measuring axial and torsional deflections on specimens tested in axial/torsional machines. The 3550HT Axial/Torsional Extensometers are available in versions rated to 1200 °C (2200 °F) or 1600 °C (2900 °F). These are externally supported and use a special bracket for load frame mounting.
MODEL 3565 Bolt Extensometers for Proof Load Testing
Designed for measuring small measuring strain ranges as required for proof load testing of bolts and similar applications such as yield measurement.
MODEL 3560 Bi-Axial or Axial Averaging Extensometers
A single integral unit provides simultaneous lateral (transverse) strain and averaged axial strain measurement. The unit is also available as an averaged Axial Extensometer alone.
MODEL 4013 Averaging Extensometers for ASTM D5656 Shear Tests
Designed specifically for performing tests in accordance with ASTM D5656. The deformation is measured on opposite sides of the test specimen and the output is an average of the two readings.
MODEL 4030 Submersible Extensometers
Submersible Extensometer designed for performing tests in water, saline solutions, and other liquids compatible with the materials of construction.
