Diagnose Every Machine Fault Months In Advance

Bearing lubrication	Bearing wear	Axial unbalance
Damaged rotor bars	Electrical faults	Electrical discharge via bearings
Gear friction	Structural mechanical looseness	Loose rotor bars
Loose stator windings	Misalignment	Worn/Eccentric Motor Sheave
Rotor mesh abnormality	Rotor eccentricity	Radial unbalance
Rubbing/Friction	Shaft eccentricity (Motor)	Significant change in vibrations
Stator eccentricity	Impacting	Kiln refractory looseness

*Full diagnostic fault coverage is available through a combination of Halo R4000 motor sensors and Halo U2000 low RPM sensors.
