Abstract
A damper having an external armature that is symmetric about a longitudinal axis, an internal armature that is arranged partially inside the external armature and a vibration absorber that in a damped manner couples the internal and external armatures together. The damper having •an arm parallel to the longitudinal axis, fixed in the manner of a cantilever to one of the armatures and provided with a magnetic dipole; •at least one 3D Hall-effect magnetic sensor, secured to the other armature and positioned facing the dipole parallel to the longitudinal axis and separated from the dipole by a determined gap; •at least one temperature sensor positioned in thermal contact with the vibration absorber; •at least one force sensor arranged in such a way as to generate data indicative of pressures or loads experienced by the vibration absorber; •a transmitter of the data generated by the sensors; •an electrical power supply.
