Extension is measured by attaching two counterbalanced extensometer clamps to the specimen at a preselected gauge length.
When tensile forces are applied to the specimen by the testing machine, the slightest change in gauge length is measured by a precise LVDT transducer. If the range of this LVDT transducer is exceeded, measurement of elongation and strain transfers to an optical encoder.
Signals from the LVDT and optical encoder are fed into the signal conditioner interface for processing. The 100S extensometer can be fitted to all twin-screw materials testing machines and must be used under software control.
