BMT-EV – NOPIX VIDEO EXTENSOMETER
BESMAK® BMT-EV Series Nopix Video Extensometer is a state-of-the-art, non-contact strain measurement system based on advanced Digital Image Correlation (DIC) technology. This extensometer system delivers high-precision strain measurements combined with a user-friendly graphical interface.
It allows researchers to focus on the experiment while capturing real-time strain data during tensile, compression, bending, shear, torsion, and fatigue tests – all without physically touching the specimen. The BMT-EV video extensometer introduces the latest imaging technology to materials testing, providing accurate and reliable strain readings even for materials and situations where traditional clip-on or contact extensometers are impractical.
Standards:
- ISO
- ASTM
FEATURES
- Standard single-camera gauge length: up to 240 mm (optional configurations available for smaller gauge lengths around 130 mm).
- Gauge length is selectable, with capability for single or multiple virtual gauge lengths as required.
- Data acquisition rate adjustable between 75 Hz and 200 Hz to suit different test speeds.
- Capable of detecting both axial and transverse (radial) strain localization and necking.
- Can be utilized in torsion testing to measure angular deformation without contact.
- Auto-adjusting lighting system optimizes illumination for the test specimen.
- Stackable camera design: multiple units can be mounted side-by-side to effectively increase the measuring length for larger specimens or higher elongations.
- User-friendly graphical interface for setup, calibration, and real-time strain visualization.
- Supports a wide range of digital output formats and communication protocols for data integration.
- Easily upgradeable and expandable system architecture to meet evolving testing needs.
- Accuracy conforms to ISO 9513 Class 1 (with an option for Class
