Description

Features

Contact less No clamping =no mechanical influence of a mechanical sensor to the specimen:
• High precision
• No specimen influence/damage
Measurement of the strain at failure (no mechanical limitation of the sensor)
Material independent Wide application field on all materials
Soft and rigid materials can be tested
Strains from 0,0005% (=5µm/m) to 1000%
Flexible field of view Specimen size of a few mm to some m
For strains from 20µm/m until 1000%
Used at small and large tensile test machines
One system for
• Different testing machines in one laboratory
• Different tasks
Camera-based Easy specimen marking
Can be used for tiny specimen due to enlarged image visualisation
Recording of movies for documentation and quality control
High precision, high speed
Simultaneous measurement of longitudinal and transversal strain
Live-camera-view Fast system setup
Precise specimen alignment
Different data interfaces Compatible to all tensile test machines
Fully integrated with tensile test machines
Analogue or digital data interface to test machine
Usual data logging and determination of material properties (e.g. Young’s module) by the tensile test software
Automatic control through tensile test machine/software
Calibration Quick and precise system calibration
Testing according to standards without mechanical sensor tracking
