American Extensometer
TTM-6191 Features
This 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.
Full bridge, 350 ohm strain gauge design for compatibility with nearly any test system.
Standard units meet ASTM class B-1 requirements for accuracy.
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 overtravel stops in both directions. Cable stops are used for overtravel protection where required. Cable stops are fully contained between the arms of the extensometer and do not hang below where they can interfere with fixturing–especially during compression testing.
