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.

Dynamic Analysis & Measurement

The Dynamic Analysis & Measurement software was specially conceived to make up for the inability to get accurate measurement during a tensile test at very high speed.

From an avi movie recorded with a very high speed camera during a test, the software is able to track marks and measure strain. We can also synchronize this data with the tensile machine data such as force or frame position, bringing high-precision data at very high speed (20 m/s).
