 LIMESS RTSS

 

The RTSS Videoextensometer measures the longitudinal and transversal strain during material tests (e.g. tension, compression tests). The system can be used for flat and round specimen at field of view (FOV) of 10mm 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. 

 

Advantages of the RTSS Videoextensometers

  • Fast setup and easy specimen marking
  • Flexible field of view from a few mm to some m
  • Suited for all tensile test machines
  • Independant of the material
 RTSS for longitudinal and transversal strain measurement
Simultaneous measurement of longitudinal and transversal strain.
