RTSS Videoextensometer - Contactless Strain Sensor for Material testing
|
![]() |
The RTSS Videoextensometer measures the longitudinal and transversal strain during material tests. It is used for tension tests, compression tests and fatigue tests up to VHCF /1000Hz. The system can be used for flat and round specimen at field of view (FOV) of 5mm to 1000mm. For rope testing a FOV up to 5m can be realized. Strains from 0.0005% to 1000% can be measured. |
The RTSS (Real Time Strain Sensor) can be intregated via different interfaces as a strains sensor and can be fully integrated in a tensile test machine. Further offline analysis modules for the determination of strain distributions and crack length (e.g. long term tests) are available. The RTSS system can be upgraded to a Q400 2D or 3D DIC system. |

Product-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. |
RTSS_CREEP | Simultaneous measurement of up to 10 specimen with a single high resolution camera that captures all specimen at the same time. This system is typically used for crep testing applications.. |
