Condition Monitors
From large turbine generator protection to general-purpose rotating machinery monitoring, SHINKAWA offers monitors/systems to fit the size of your production assets. Our extensive selection of options allow for systems just right your needs.
- VM-5 Series
- ［For monitoring of turbines/general-purpose rotating machinery/low temp (Ex. LNG)］
- A monitor used for monitoring Shaft Vibration, Axial Position, Eccentricity, Temperature, Rotational Speed, etc. 8 and 10 slot rack mount types, Power source built-in standalone type are available for flexibility.
| Vibration | Axial position | Eccentricity | Expansion | Differential expansion |
|---|---|---|---|---|
| ○ | ○ | ○ | ○ | ○ |
| Rotational speed | Phase mark (phase reference) |
Valve opening | Temperature | |
| ○ | ○ | ○ | ○ |
- VM-7 Series
- ［For monitoring of turbine/general-purpose rotating machinery］
- A monitor designed to meet the requirements of International Organization for standardization (ISO) standards and the American Petroleum Institute (API) standard 670. The system covers the features for protective monitoring of critical rotating machinery in plants specified in the API Std.
| Vibration | Axial position | Eccentricity | Expansion | Differential expansion |
|---|---|---|---|---|
| ○ | ○ | ○ | ○ | ○ |
| Rotational speed | Phase mark (phase reference) |
Valve opening | Temperature | |
| ○ | ○ | ○ | ○ |
- VM-21 Series
- ［For monitoring of general-purpose rotating machinery］
- Signal conditioner that accepts signals from transducers installed, convert the signals to isolated 4-20 mADC or 1 to 5VDC signals.
| Vibration | Axial position | Eccentricity | Expansion | Differential expansion |
|---|---|---|---|---|
| ○ | ○ | ○ | ○ | ○ |
| 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. |
Note: The monitoring parameters shown for each product series are only applicable when these are used for Turbine Supervisory Instrumentation (TSI). They might be used for other measurement and monitoring applications.
