The XTOP3D XTDIC-VG video extensometer overcomes the limitations of traditional methods, such as data discontinuity and significant human error. It allows for the configuration of virtual gauge lengths and operates in synchronization with testing machines, capturing the entire process—from initial material damage and strain evolution through to final fracture. Suitable for a wide range of complex testing environments, the system delivers precise mechanical data and fatigue curves, supporting applications in material R&D, structural optimization, and equipment service-life assessment.

The XTOP3D XTDIC high-temperature 3D full-field strain measurement series is designed for extreme high-temperature testing environments, such as those in the aerospace and nuclear energy sectors. By integrating proprietary technologies—including blue-light filtering, specialized high-temperature speckle patterns, and coaxial optical imaging—the system effectively eliminates interference from thermal radiation. It enables precise measurement of welding deformation and composite material tensile/compressive behavior across a wide temperature range (up to 2500°C), delivering accurate and reliable full-field strain and displacement data with a deviation of ≤5% compared to simulation results. This supports the analysis of thermal structural damage and the precise assessment of component service life.

The XTDIC-VG video extensometer measurement system utilizes Digital Image Correlation (DIC) technology, employs a single-camera optical system design, and employs a sub-pixel displacement measurement algorithm to provide high-precision, real-time measurement of transverse and longitudinal strain during tensile testing. Available in 60, 120, and 240mm field of view models, the XTDIC-VG video extensometer can be adjusted to suit the material deformation being measured.

The XTDIC-VG video extensometer is easy to calibrate, eliminating the need for perfect test specimen alignment. It communicates with a variety of testing machines, acquiring force information and outputting strain data. Developed based on DIC technology, it is suitable for testing conditions such as large deformation, three-dimensional deformation, thermal deformation, and in-cavity deformation, and is particularly well-suited for material characterization during tensile testing.

The XTDIC-VG video extensometer is designed for data acquisition on brittle or thin materials and specimens undergoing extreme deformation, ensuring measurement accuracy across a wide field of view. It offers seamless connectivity and compatibility with various types of testing machines and is suitable for a wide range of materials, guaranteeing precision in strain measurement experiments.
