Description
SHINKAWA VM-5K SST-2194-001-P001G Product Description
Product Overview
SHINKAWA VM-5K SST-2194-001-P001G is a dual-channel vibration monitoring module within the SHINKAWA VM-5 Series, developed for continuous monitoring of shaft vibration on critical rotating machinery. The VM-5K accepts transducer signals, processes and displays vibration measurements, and provides configurable ALERT and DANGER alarm functions for early detection of abnormal mechanical conditions. SHINKAWA specifies the VM-5 Series for rotating machinery monitoring and protection in accordance with the API 670 design concept.
The SHINKAWA VM-5K SST-2194-001-P001G is designed for integration into turbine supervisory instrumentation (TSI), compressor monitoring and machinery-protection systems. Its two-channel architecture allows simultaneous monitoring of two vibration measurement points, while built-in sensor self-diagnostics help identify transducer faults and reduce the risk of erroneous shutdowns. The VM-5K SST-2194-001-P001G can be deployed within a VM-5 rack architecture and connected with relay, power-supply and communication modules to provide a complete rotating-equipment monitoring solution.

Main Features and Advantages
Dual-Channel Shaft Vibration Monitoring
The VM-5K SST-2194-001-P001G monitors two vibration channels simultaneously, allowing operators to observe multiple shaft-vibration measurement points without installing separate independent monitors. This is particularly useful on turbine and compressor trains where vibration behavior at different bearing or shaft locations must be compared continuously.
Early Detection of Mechanical Abnormalities
The monitor provides independently configurable ALERT and DANGER thresholds. When vibration exceeds the configured limits, the monitoring system can generate corresponding alarm information, allowing operators and maintenance personnel to identify developing mechanical problems before they progress into bearing damage, rotor instability or other costly failures.
VM-5K
Built-In Sensor Self-Diagnostics
A significant advantage of SHINKAWA VM-5K is its self-diagnostic capability for the input transducers. This helps distinguish an actual machinery vibration condition from a sensor or measurement-loop fault, reducing the possibility of inappropriate alarm interpretation or unnecessary machine shutdown.
Clear Front-Panel Monitoring
The module provides digital and bar-graph indication for the two channels, allowing vibration values and configured alarm information to be checked locally. SHINKAWA’s VM-5 architecture allows operating status and configuration to be reviewed from the front panel without interrupting normal machine operation.
Flexible Signal Processing
The VM-5K supports optional filtering and True RMS processing. SHINKAWA specifically lists RMS rectification as an available option for VM-5K, allowing the monitoring system to calculate true RMS vibration values where this measurement method is required. Recorder outputs can also be configured for standard or alternative voltage/current ranges.
Broad Sensor Compatibility
The VM-5 platform supports SHINKAWA transducers and various sensor families, while also offering compatibility with existing third-party transducer inputs in suitable configurations. This flexibility is valuable when upgrading or maintaining established machinery-monitoring installations without replacing all field sensors.
Modular Protection-System Architecture
The VM-5K operates as part of a modular monitoring architecture that can combine vibration, eccentricity, axial position, differential expansion, speed and other parameters. Related relay, power-supply, interface and communication units allow the monitoring rack to exchange status and alarm information with plant automation and protection systems.
Application Fields
SHINKAWA VM-5K SST-2194-001-P001G is primarily used in rotating machinery condition monitoring and turbine supervisory instrumentation (TSI). The VM-5 Series is designed for applications ranging from smaller compressors to gas turbines and large steam-turbine generator systems, making the VM-5K suitable for both process-industry machinery and large power-generation assets.
In power-generation plants, the VM-5K can monitor shaft vibration on steam turbines, gas turbines, generators and associated rotating equipment. Continuous vibration information helps identify imbalance, misalignment, mechanical looseness, bearing deterioration and other developing faults.
In oil and gas and petrochemical facilities, the module can be applied to centrifugal compressors, turbine-driven compressors, pumps and other critical rotating equipment. Its configurable alarm thresholds allow machinery-monitoring signals to be incorporated into plant DCS, PLC, ESD or dedicated protection systems.
In chemical and process industries, the VM-5K provides continuous vibration surveillance for compressors, pumps, fans and other high-value rotating machinery. Early identification of abnormal vibration can help reduce unplanned shutdowns and support condition-based maintenance.
In metallurgy, pulp and paper, marine and heavy industrial applications, the module can form part of a larger VM-5 monitoring rack containing vibration, thrust, eccentricity, speed and other measurement functions. Its modular design makes it suitable for legacy machinery-protection systems where reliable replacement of individual monitoring modules is preferable to replacing the entire monitoring architecture.
