Overview
The Instron AVE3 Advanced Non-Contact Video Extensometer is an engineered optical strain measurement system designed for high-fidelity, real-time axial and optional transverse strain acquisition during mechanical testing. Based on digital image correlation (DIC)-enabled video metrology, the AVE3 captures sub-pixel displacement of surface features on specimens under load—without physical contact—thereby eliminating mechanical interference, knife-edge slippage, or premature failure at clamping points. It operates across tensile, compressive, and flexural test modes, supporting standardized strain-controlled protocols per ISO 6892-1, ASTM E83, and ISO 9513 Class 0.5 accuracy requirements. With native 500 Hz data streaming and onboard real-time processing, the AVE3 enables closed-loop strain rate control down to 0.00025/s—critical for r-value determination, yield point detection, and post-yield behavior analysis in metallic sheets and high-ductility polymers.
Key Features
- Patented Constant-Density Air Tunnel (CDAT) technology mitigates thermal drift and ambient airflow-induced noise, ensuring stable strain signal fidelity without aggressive post-processing filtering.
- Adaptive illumination system decouples measurement performance from lab lighting conditions—enabling consistent contrast and edge detection regardless of ambient light variability.
- Fan control integration synchronizes cooling activation exclusively with test execution, minimizing vibration coupling and thermal perturbation during critical deformation phases.
- Magnetic lens mount system guarantees repeatable, factory-calibrated positioning across interchangeable lenses (6 mm, 9 mm, 16 mm, 35 mm), supporting specimen gauge lengths from 10 mm to 250 mm and total elongation up to 1000%.
- Native integration with Bluehill® Universal software provides seamless configuration, real-time visualization, synchronized DIC image capture, and automated report generation compliant with 21 CFR Part 11 audit trails.
- Onboard FPGA-based processing delivers deterministic latency and jitter-free 500 Hz strain output—fully compatible with Instron’s strain-controlled test methods and third-party DAQ synchronization.
Sample Compatibility & Compliance
The AVE3 accommodates a broad spectrum of material classes and geometries: metallic sheets (including AA5052, DP980), thermoplastics (PP, PC, PA6), fiber-reinforced composites (CFRP, GFRP), elastomers (NR, SBR), thin films (<100 µm), paperboard, biomedical scaffolds, and textile laminates. It supports standard specimen configurations per ISO, ASTM, JIS, and GB/T standards—including dog-bone, flat strip, round bar, and bend fixtures. The system meets ISO 9513:2012 Class 0.5 calibration traceability and complies with ASTM E83–23 Annex A1 for extensometer verification. For regulated environments, Bluehill® Universal with AVE3 satisfies GLP/GMP documentation requirements, including electronic signatures, user access controls, and immutable audit logs aligned with FDA 21 CFR Part 11.
Software & Data Management
AVE3 operates as a tightly coupled subsystem within Bluehill® Universal v4.x or later, sharing the same host PC environment (Windows 10/11 64-bit, Intel i3 @3.0 GHz, ≥16 GB RAM). All measurement parameters—including ROI definition, lens selection, exposure time, frame rate, and strain averaging window—are configured directly in the test method editor. Strain data streams synchronously with load and displacement channels at full 500 Hz resolution, stored in vendor-neutral .csv and proprietary .bhuniv formats. Optional AverEdge32™ module implements real-time 32-point axial segmentation for r-value calculation per ISO 10113 and ASTM E517, while DIC add-on licenses enable full-field strain mapping (εxx, εyy, γxy) with pixel-level registration to force-displacement curves.
Applications
The AVE3 serves as a primary strain sensor in R&D labs, quality control facilities, and certification bodies performing mechanical characterization per international standards. Typical use cases include: high-precision r/n-value determination in automotive sheet metal stamping validation; low-strain modulus measurement in CFRP laminates per ISO 527-4; ductility assessment of biodegradable polymer films per ASTM D882; creep compliance tracking in thermoplastic elastomers per ISO 37; and fracture strain quantification in brittle ceramics under three-point bending per ISO 178. Its non-contact architecture makes it uniquely suitable for explosive failure events, hygroscopic specimens, cryogenic testing in environmental chambers, and aqueous immersion tests where traditional clip-on extensometers are impractical or unsafe.
FAQ
Does the AVE3 require recalibration when switching lenses?
No—each lens is pre-calibrated at the factory and recognized automatically via the magnetic mount ID; no user recalibration is necessary.
Can AVE3 be used with non-Instron test frames?
It is validated only for Instron systems (3300, 5900, 6800, and 3400 series), including environmental chambers and water baths; third-party frame integration is not supported.
Is transverse strain measurement available on all models?
Transverse measurement is an optional hardware configuration—only enabled on units ordered with dual-camera optics and corresponding firmware licensing.
What is the minimum gauge length supported with the 6 mm lens?
The 6 mm lens supports gauge lengths as short as 10 mm, with optimal performance between 15–75 mm depending on specimen surface texture and contrast.
How does CDAT technology improve measurement stability?
CDAT actively equalizes air density gradients along the optical path using laminar flow management, reducing refractive index fluctuations that cause sub-pixel tracking error—particularly critical below 0.1% strain.
