2. Technical Features
2.1 High-Precision Monitoring with Excellent Working Condition Restoration
Equipped with Shinkawa’s exclusive high-precision acquisition and computing chip, the overall measurement accuracy reaches ±0.15%FS, with ultra-high sampling resolution and linearity to precisely capture micron-level vibration parameter fluctuations of units.Its temperature stability is ±0.15%FS/℃ and long-term pressure stability is ±0.05%FS/year, which effectively offsets measurement deviation caused by temperature variation and ambient pressure fluctuation. No zero drift or data distortion occurs during long-term operation, and it can fully restore dynamic vibration characteristics of large rotating machinery under all working conditions to meet precise condition monitoring requirements of high-end industrial units.
2.2 Fast Dynamic Response Adaptable to Transient Unit Conditions
With optimized high-speed signal processing algorithm, the overall response time is ≤ 1s, which can track transient vibration changes during unit startup/shutdown, load ramp-up, load reduction and condition switching in real time and eliminate monitoring lag and data delay.It rapidly captures and records instantaneous vibration peaks caused by startup impact and sudden load change of turbines and compressors, and completely retains data of sudden equipment condition changes to provide complete basis for unit fault tracing, condition analysis and parameter optimization.
2.3 Standard Industrial Design with Strong Compatibility
Designed strictly in accordance with API 670, the authoritative standard for rotating machinery monitoring in petrochemical and power industries. Its hardware architecture, signal output and interlock logic are fully compatible with mainstream power plant TSI monitoring systems and industrial automatic control systems.It is natively compatible with the complete rack and configuration system of Shinkawa VM-5 series, and can seamlessly connect with various mainstream PLC and DCS control systems to support remote upload, centralized monitoring and screen configuration of vibration data without additional adapter devices, suitable for renovation and capacity expansion of monitoring systems for new and legacy units.
2.4 Comprehensive Self-Diagnosis & Interlock Protection for Controllable Maintenance
A complete board-level and channel-level self-diagnosis mechanism is embedded to monitor hidden risks such as sensor open circuit, short circuit, out-of-range signal, loop abnormality, hardware fault and signal distortion in real time, covering all fault scenarios of vibration monitoring loops.The module supports custom configuration of multi-level alarm thresholds to realize graded interlock output for high alarm and high-high alarm of vibration. When an abnormality is triggered, fault sequence, peak data and operation logs are automatically recorded. Combined with system SOE event logging, root causes can be quickly located to support predictive maintenance and effectively prevent equipment wear, shaft damage and unplanned shutdown accidents caused by excessive unit vibration.
2.5 Industrial Rugged Protection Adaptable to Harsh On-Site Conditions
Adopting sealed plastic reinforced structure and industrial triple-proof (dustproof, moisture-proof, anti-corrosion) design, it features dust resistance, moisture resistance, vibration resistance, aging resistance and electromagnetic interference immunity, which can effectively resist electromagnetic noise and voltage interference generated by startup/shutdown of high-power equipment and inverter operation in power and chemical plants.The service life of relay contacts exceeds 100,000 times. The hardware structure is stable without vulnerable parts and has an extremely low failure rate. It supports 24/7 non-stop continuous monitoring and perfectly fits unattended normal operation mode of industrial sites.

4. Working Principle
Based on the API 670 standard monitoring architecture, the SHINKAWA VM-5Y1-02/GEM 1594-005-P001G module implements a closed-loop unit vibration monitoring workflow: field vibration signal acquisition → filtering, noise reduction and waveform shaping → high-precision calculation and analysis → parameter comparison and judgment → data upload and interlock output → fault self-diagnosis and protection.
During unit operation, the module receives analog vibration signals from field vibration sensors for shaft vibration and bearing vibration in real time. The signals go through multi-stage electromagnetic filtering, noise reduction and waveform shaping to eliminate false data caused by on-site electromagnetic interference and line jitter.
The module continuously monitors loop status, signal quality and hardware operation of each channel, and compares real-time vibration parameters with safety thresholds throughout the operation.
