KNOW HOW in INSTRUMENTATION
One of the main goal of a laboratory making mechanical tests is to produce and maintain a high level of know-how in instrumentation. The « Laboratoire Essais Mécaniques, Structures et Génie Civil LEMSC » (Mechanical Testing, Structures and Civil Engineering Laboratory) tries as far as possible to follow the numerous current technical developments in instrumentation. Several technical keypoints of our lab can be highlighted:
- High knowledge in strain gauges technics,
- Proficiency in the use of accelerometers, displacement transducers, load cells, temperature sensors, …
- Validation of the measurements by internal calibration,
- Experience in tools and setups developments,
- In high temperature and cryogenic tests,
- Regular use of measurements by cameras and DIC technics
- Mastery of the electronics of a large part of the equipment (home-made!)
- Development and integration of our own electronics cards for sensors signal conditioning and instrumentation,
- Possibility to develop data acquisition applications, statics and dynamics modules,
