VidéoTraction®

Principle of operation

The systems in the VideoTraction® range are based on real-time monitoring of the elements of a part or a sample. The monitoring of these elements allows deformations, elongations or displacements measurement, in different directions. The use of very high resolution cameras (up to 18 Megapixels) and development of very high level algorithms improve measurement accuracy and enable  very small deformations or displacements measurement (a few microns).

On the other hand, VideoTraction® systems are particularly well suited for dynamic tests of up to 40Hz (traction, fatigue, traction / torsion, etc.) by offering very high speed cameras (more than 1,000 i / s in real-time) thus allowing piloting of test at deformation speed.

The VideoTraction® systems are adaptable and already integrated on almost all traction machines on the market and perfectly synchronized with the machine control software.
