Cetim answer

Support in the development of a connected washer thanks to its expertise in mechatronics :

Support in the integration of strain gauges and electronics into the washer

Delivered results

Development of a first connected washer and its scanner (marketed in 2020) allowing to :

– Ensure that the nuts are properly tightened thanks to an axial tension measured by the device

– Know the wrong tightening on the same engine by scanning every nut equipped

In the end, this technology could be integrated into nuts and borescope plugs
