The various parameters of physical processes are widely used as condition indicators,
among which vibration is the most popular one since it contains information about almost all processes occurring in active machines.
Efficiency of status indicators is illustrated by the graph of degradation of the machine condition during operation, which shows possible
time to detect the signs of these changes.
Compared to smoke, increased temperature and noise, even a relatively simple vibration parameter has the advantage of early identification of problems.
Thanks to this, there is time to plan maintenance or repair in the most convenient time for the object user.
