Video Extensometer – Quantum Series
Non-Contact Video Extensometer – Quantum Series provides precise, real-time strain measurement with advanced DIC technology, offering accuracy, safety, and versatility for diverse material testing applications.
Qualitest’s latest video extensometer features cutting-edge Digital Image Correlation (DIC) technology, providing a non-contact solution for measuring elongation, extension, deformation, and deflection (strain).
Key Features:
- Measure What You See: As long as the test specimen remains visible, the extensometer captures data throughout the testing process.
- Reanalyzable Test Data: Test data is saved as images, allowing users to adjust the gauge length or measurement location post-test without re-running experiments.
- Simultaneous Axial & Lateral Measurements: Unlike conventional contact-based systems, this extensometer records both axial and lateral strain without needing multiple sensors.
- Streamlined Operation: Its contact-free design eliminates complex attachment and removal steps, reducing wear and tear, extending device longevity, and improving safety—especially in destructive or extreme-temperature tests.
- Eliminates Slippage & Alignment Errors: With no physical contact, common issues like slippage and misalignment seen in traditional extensometers are avoided, ensuring precise measurements.
- Comprehensive Data Tracking: The system monitors tests from start to finish, enabling accurate software-based elongation calculations.
- Advanced Connectivity:
- Analog Output: Real-time measurements can be exported to third-party devices.
- Digital Output: Data sharing via serial port or TCP/IP.
- Analog & Digital Input: External device signals can be integrated for comprehensive analysis.
Qualitest’s video extensometer is a powerful, efficient, and adaptable tool for advanced material testing across various industries.
How Does It Work?
What is pattern？
A pattern is a cluster of points that stand out from their surroundings due to significant differences in gray levels, much like constellations are identified by the arrangement and distribution of stars.
How Does it Track?
The system sets the initial pattern as a reference and identifies its geometric center. It continuously monitors deviations from this reference and tracks the center's movement. If a portion of the pattern is missing or deformation surpasses the confidence threshold, the system updates the reference to the most recently detected pattern.
