Main features
  • Quick attach kit wire forms for large specimens
  • Adapter kits to change gauge lengths
  • Connectors to interface to nearly any brand of test equipment
  • Special coatings and stainless steel knife edges available for biomedical tests

May be left on through specimen failure.

  • Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
  • Standard units meet ASTM class B-1 requirements for accuracy. A test certificate is included. ISO 9513 class 0,5 test certificates are available upon request.
  • All models can measure in both tension and compression and can be used for cyclic testing.
  • Standard quick attach kit allows one hand mounting to specimens.
  • Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this also allows cyclic testing at higher frequencies.
  • All models have mechanical over travel stops in both directions. Cable stops are used for over travel protection where required. Epsilon’s cable stops are fully contained between the arms of the extensometer and do not hang below where they can interfere with fix Turing–especially during compression testing.
  • Hardened tool steel knife edges are easily replaced. A spare set comes with every extensometer.
  • Gauge length adapter kits enable configuration of multiple gauge lengths with one extensometer.
  • Replaceable arms and spacers for ease of repair.
  • High and low temperature options extend operation from as low as -270°C to +200 °C (-454 °F to +400 °F).
  • Includes the Calibration system for on-site electrical calibration.
  • Includes high quality foam lined case.
General description

The extensometer is designed for testing a wide range of materials, including metals, plastics, composites and ceramics. All will perform both tension and compression strain measurement. The dual flexure design makes them very rugged and insensitive to vibrations, which permits higher frequency operation.
Its is able to mount the extensometer on the test specimen quickly and easily with one hand. The quick attach kit can be removed, allowing mounting of the extensometer with springs or rubber bands.

The extensometer is a strain gaged devices, making the compatible with any electronics designed for strain gaged transducers. Most often it is connected to a test machine controller, and equip the extensometer with a compatible connector wired to plug directly into the controller. For systems lacking the required electronics, we can provide a variety of solutions for signal conditioning and connection to data acquisition systems or other equipment.
For gauge lengths less than 20 mm (0.8 inches).
