This accurate, strain gaged extensometer is most often used on round specimens tested in bi-axial test machines capable of simultaneous axial and torsional loading.
The extensometer is often customized for particular applications.
All units are capable of bi-directional travel, so they may be used for cyclic testing under fully reversed loading conditions.

The standard sized model is self-supporting on the specimen, and works on specimens from 9.5 to 25.4 mm diameter, typically solid or turbular metal or composite specimens. The conical point contacts included with
the extensometer are made from tungsten carbide.
The unique design directly measures the surface shear strain angle, which allows operation on a wide range of specimen diameters without changing the calibration. All models are designed specifically to minimize crosstalk between axes and to provide high accuracy measurements. All feature a strong, dual flexure design.

Because these transducers are so often used for specialized tests, contact us with your specific test needs. We can then recommend the ideal configuration specifically for your tests.

The application range includes

• Static to cyclic axial/torsional testing including reverse loading
• Can be used also for single axial or torsional measurements

Features

• Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
• Self-supporting on the specimen.
• Cyclic testing may be performed at up to 2 Hz.
• Includes the Shunt Calibration System for on-site electrical calibration.
• Rugged, dual flexure design for strength and improved performance – much stronger than single flexure designs.
• Includes high quality foam lined case
