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 100R extensometer can be fitted to all sizes of screw-driven materials testing machines.
