RTSS video extensometer

for material testingfor the aeronautical industry

With the Videoextensometer, the longitudinal and transversal strain is measured during material tests (e.g. tension, compression tests). Further analysis modules for the determination of crack length (e.g. long term tests) and crack areas (e.g. bondings) are available. A Wide Range of Applications The Videoextensometer RTSS is perfectly suited for the determination of material properties in tension tests. The specimen’s deformation is measured contactlessly. Properties like Stress-strain curves, E-modulus and Poisson’s ratio are determined. Advantages of the RTSS videoextensometer Contactless and camera based Strains from 20µm/m up to more than 1000% can be measured Flexible specimen size from a few mm to some m Fast setup and easy specimen marking Suitable for all testing machines Can be used on all materials Options RTSS_HR: - High resolutions videoextensometer for quasi static tensile tests. Measurement precision for strain is 20µstrains (=20µm/m) RTSS_HS: - Fast videoextemsometer. Due to its high measurement rate the videoextensometer can be used also for dynamic applications (e.g. hydro pulser) and for the control of fast processes. Multi-Camera-System: - + Simultaneous measurement of different specimen sides. + Combination of a small and a large field of view –> High precision measurement of E-modulus and measurement of the complete Force-Strain-curve. + Stereo Setup: Two cameras at a defined distance measure each with small a field of view one marker –> Highest precision for rigid materials. More Features Contactless – no clamping of a mechanical sensor to the specimen Measurement of the strain at failure
