The benefits of monitoring rotating equipment with vibration sensors and process parameters are well known

• Analyze bearing performance
• Examination of critical speeds in runup/rundown modes
• Data comparison at known speeds
• More reliable trends
• Ability to set up more accurate limits
• Examination of blade frequencies
• Full FFT processing of runup/down data
• Historical data storage
• Better control of machine rotor startup

With this information the operator and plant rotating equipment expert are better able to detect the following problems:

• Shaft unbalance
• Whirl problems
• Shaft rubs
• Shaft bowing
• Bearing faults
• Generator shorts
• Damaged sealing strips
• Misalignment
• Shaft cracking
• End winding vibrations
• Looseness
