Product Description
Displacement and strain measurement under normal environmental conditions.
Core Technology
Technical Specifications
LVE (Linconst Video Extensometer) Video Extensometer is a non-contact real-time high-precision strain measurement system. It is based on a separate camera and real-time image processing algorithms. By capturing images of the experimental process and analyzing the changes in image features, it can dynamically and in real-time measure strain, displacement, and other data. It is compatible with testing machine signals and can measure various mechanical property parameters such as stress-strain curves. Suitable for all types of mechanical tests. Test
LVE-PRO Series video extensometers support both standard and extended measurement modes, catering to high-precision testing requirements within the standard field of view while also offering scalability for wide-field measurements. They can flexibly handle various testing conditions. The LVE-PRO Series can simultaneously measure both longitudinal and lateral strains, providing real-time longitudinal and lateral strain curves of the specimen. Optional full-field strain modules are available for full-field cloud map calculations.
Product Features
1. Non-contact measurement methods
Avoid additional influence on measurements from contact methods such as strain gauges and extensometer holders.
Especially suitable for materials such as films and gels that cannot be tested using traditional contact methods.
2. Full-process tracking supported
Continuous operation without interruption, sample breakage won't damage the measuring equipment, and full-process traceability is available.
Especially suitable for testing the maximum elongation, breaking elongation, and elongation after break for scenarios involving steel wire ropes, steel wire strands, and rebars.
3. Suitable for various scenario testing
In addition to pull, compression, and bending tests at room temperature, the LVE-PRO unit also supports special tests in high and low-temperature environments.
4. Suitable for various material and part testing
Material limitations are minimal, allowing for testing of specimens with various sizes and materials.
The LVE equipment is suitable for testing various materials such as metals, rubbers, films, ultra-fine wires, and more, as well as for testing various shaped workpieces and components (e.g., bolts).
5. Wide measurable strain range
Supports strain testing over 1000%, far exceeding traditional methods.
Especially suitable for large deformation tests, such as large deformation tests of geotechnical materials and medical rubber gloves.
6. Easy and flexible to use
Set the gauge length arbitrarily; one machine is equivalent to N extensometers of different specifications.
Simultaneous calculation of longitudinal and lateral strains supported, meets Poisson's ratio testing requirements, and can also satisfy bidirectional testing needs.
Accommodates variable measurements across multiple points, suitable for multi-sample testing and multi-section testing, etc.
7. High measurement accuracy, equipped with vibration resistance testing on-site
Based on image processing techniques, the calculation accuracy reaches sub-pixel levels, representing a significant improvement over traditional visual tests.
Supports metrological calibration according to international standards, meeting the 0.5-grade extensometer accuracy requirements.
Self-developed anti-vibration algorithm, better suited to actual testing requirements.
8. Supports offline mode, with expandability for the entire site's contingency module
Features offline mode for revisiting previous measurement processes and supports reanalysis with parameter changes.
Supports importing external images for analysis and calculation.
Supports expansion of the full-range adaptive module, capable of conducting 2D strain field and displacement field tests.
