This course assesses the cause and evolution of mechanical failures by analysis of vibration signals.
It emphasizes the implementation of an efficient predictive maintenance program.
Public :
Engineers, supervisors and technicians involved in the technical inspection and maintenance of rotating equipment.
Level :Skilled
Prerequisite :
Provide evidence of a professional experience of at least 1 month related to the concerned field.
