Technical Specifications
Produkt-Variants:
| RTSS_Cx: |
High resolution video extensometer for quasistatic tensile tests.
Measurement resolution for strain down to 5µstrains (=5µm/m)
|
| RTSS_HS: |
Fast video extensometer for dynamic tests.
The high measurement rate makes the system suited for dynamic applications (e.g. on a Hydropulser) and for the control of fast test.
|
| Multi-camera-Systems: |
Multi camera setups for:
- 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 l0 distance measure. Each camera has a small field of view and measures one marker → Highest precision for rigid materials (small strains).
