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
× ×
Condition Monitoring Parameters for Rotating Machinery
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.
