Contexte et objectifs
We had a request to carry out closed cell tensile tests on irradiated materials for monitoring tanks in a nuclear environment. The main objective was to have an efficient measurement system allowing implementation in a tele-operated manner 
Constraints
- Temperature tests – Constraints linked to the thermal enclosure: -150°C and +450°C
- Conditions of use and handling of the device: The system must be installed using an assembly adapted to the climatic chambers present for each machine
- Required measurement performance: class 0.5 according to ISO9513 standard
- Use of measured data transfer of data in real time to the machine control software to allow regulation of the signal measured by the video extensometer
- Required precision below one micron
Solution
To meet this request we installed version FVX02 of VideoTraction which perfectly met all the customer's expectations.
