Extensometers

Model 100R Long Travel Extensometer

The Tinius Olsen model 100 R is a high elongation extensometer that is designed to measure the ‘stretch’ of a wide range of materials. The initial measuring length, or gauge length, can be changed to suit the specimen size or the test standard that is being applied.

The unique design ensures an extremely low tracking force for testing sensitive materials combined with a robust construction to easily withstand the high release forces and breaking energies with certain specimens. The design also incorporates a simple yet effective method with which the extensometer followers are attached to the specimen, so allowing rapid testing throughput.

Extension is measured by attaching two counterbalanced extensometer clamps to the specimen at a pre-selected gauge length. When tensile forces are applied to the specimen by the testing machine, the slightest change in gauge length is measured by an optical encoder. Signals from the optical encoder are fed into the signal conditioner interface for processing.

The 100 RC extensometer can be fitted to all sizes of screw driven materials testing machines.
