X-Sight 4000-3D Optical Extensometer with Stereoscopic Camera System

• All-in-one box extensometer
• Ideal for general tensile tests
• 3D capabilities
• Resilient to out-of-plane error

The X-Sight 4000-3D Series is a universal stereoscopic video extensometer (3DVE) equipped with two cameras to capture spatial movements and deformations. Its 3D capability ensures resilience to errors caused by out-of-plane movements, enhancing accuracy.

The 3DVE provides multiple measurements simultaneously, allowing for data collection at different positions or with various gauge lengths. It measures strain, total length, delta length, angle, and more, making it ideal for comprehensive material testing, sophisticated research and quality control that requires 3D data analysis.

When to Use X-Sight 4000-3D?

• Whenever we deal with very thin samples or weaker grips that may cause the specimen to bend and move out of plane
• During compression tests, the middle of the sample may bulge outward and move out of plane (barreling)
• If the sample bends or twists and moves out of plane during compression (buckling).
• When the sample is already curved at the start of the test
• When measuring points in different planes, e.g., on a rebar coupler
• During component testing of generally 3D objects

Why extensometer 3D?

• Prevention of measurement distortion due to out-of-plane displacement, which is not prevented by the test rig sufficiently
• Accurate measurement and determination of Poisson’s ratio of thin samples susceptible to tilting (composites, metal sheets, fabrics)
• Control of 3D movement of measured samples and adjacent parts (sample clamping system, test rig frame, etc.)
• Identification of sample cracking, bending or buckling
• Identification of non-symmetric thermal expansion deformations
• Identification and validation of actual sample deformations in 3D
• Test rig sample loading issues, test rig set-up, test rig adjustment
