- Vibration amplitude and phase angle used for
diagnostic information in Polar and Bode formats or for
vector monitoring.
- Eccentricity used to measure the shaft bow during
startup of large turbine machinery.
- Phase reference used for measuring shaft rotation
speed and phase angle of shaft vibration for monitoring
and diagnostic purposes.
- Radial vibration used for indicating bearing condition
and measuring machine malfunctions such as rotor
imbalance, misalignment, and shaft crack.
- Axial thrust position used for determining thrust bearing
wear or potential bearing failure.
- Shaft radial position used for determining shaft position
relative to rotor attitude angle, an indicator of rotor
stability and shaft alignment.
