SHINKAWA VM-5K Dual Vibration Monitor

The SHINKAWA VM-5K SST-2194-001-P001G is a high-performance dual-channel vibration monitor designed for critical rotating machinery protection. Conforming to API 670 standards, this module provides continuous monitoring of vibration parameters for steam turbines, compressors, generators, and pumps, enabling early fault detection and prevention of catastrophic failures.

Technical Specifications

The monitor delivers exceptional measurement accuracy with ±0.5% FS at 25°C and maintains ±2.0% FS across the full operating temperature range of 0°C to 65°C. The 1000 Hz sampling rate ensures capture of high-frequency vibration components, with alarm response times under 100 ms. Dual analog outputs provide 4-20 mA signals proportional to measured vibration, while RS-485 digital output supports Modbus RTU protocol for system integration.

• Input Channels: 2 independent channels

• Sensor Compatibility: FK, MS, VE, VC series sensors

• Frequency Range: 0.1 Hz to 10 kHz

• Measurement Accuracy: ±0.5% FS (25°C), ±2.0% FS (0-65°C)

• Sampling Rate: 1000 Hz

• Analog Outputs: 4-20 mA (each channel)

• Digital Output: RS-485 Modbus RTU

• Alarm Outputs: 8 relay contacts (H-danger, H-alarm, L-alarm, L-danger per channel)

Alarm and Diagnostics

The VM-5K provides programmable alert and danger alarm setpoints for each channel, with configurable time delays to prevent nuisance trips. Front-panel LCD displays both numeric values and bar graph representations of measurement status, while dedicated LEDs indicate alarm conditions. Continuous self-diagnostics monitor sensor integrity, power supply health, and internal circuit status, with fault conditions reported via dedicated relay outputs.

Installation and Integration

Designed for 19-inch rack mounting in VM-5H3 (8-slot) or VM-5W1 (10-slot) chassis, the VM-5K occupies a single slot with dimensions of 44 mm width, 177 mm height, and 250 mm depth. The module supports hot-swap installation, allowing replacement without system shutdown. Conformal coating protects circuit boards from environmental contaminants, ensuring long-term reliability in industrial applications.
