---|---|---|---|---|
○ | ○ | ○ | ○ | ○ |
Rotational speed | Phase mark (phase reference) |
Valve opening | Temperature | |
○ | × | ○ | × |
Vibration | Shaft vibration (vibration of rotor itself)and casing vibration |
---|---|
Axial position | Position of the rotor around the thrust bearing along the rotor axis |
Eccentricity | Deflection of the axis |
Expansion | Casing expansion due to heat |
Differential expansion | Relative thermal expansion differences between the casing and rotor |
Rotational speed | Rotational speed of the rotor |
Phase mark (phase reference) |
One pulse per revolution. Signals used for reference of vibration phase angle. |
Valve opening | Value represents steam control valve opening position. |
Temperature | Temperature at the bearing, etc. |
