multi sensor wireless system for eccentricity and bearing

Bearing defects also create impulses that excite structural resonances amplifying the vibrations experienced by the system and the sensor 2 As machines ramp up and down in speeds during stop/start conditions or normal operation the changing speeds create potential opportunities for system resonances to become excited leading to higher 2009-11-12f2: Eccentricity factor (typically 1 2) f3: Imbalance factor (1 0 when N = 3 and 1 2 when N = 4) For example when the net measurement weight is 8 t the weight of the hopper is 3 t and the number of load cells to be used is four 4 824 t 5 t 4 (1 3 8 3) 1 2 1 2 L = ≈ +
