SHINKAWA VM-5K-411512-000-000-111-0/IS0/EX5 Dual Vibration Monitor

Name: Shinkawa VM-5K Dual Vibration Monitor – Datasheet & Quote
Brand: Shinkawa

Description

Overview

The Shinkawa VM-5K Dual Vibration Monitor provides two-channel vibration measurement within the VM-5 series machinery protection system, allowing simultaneous monitoring of two vibration signals for rotating machinery. It delivers the measurement, alarm, and recorder functions required for turbine and compressor protection.

The module supports vibration ranges including 0 to 100 um pk-pk, 0 to 500 um pk-pk, and 0 to 15 mils pk-pk, covering common shaft and casing vibration measurement applications.

Engineering & Design

The VM-5K converts vibration sensor signals into measured values with local display, alarm functions, and recorder outputs. Alarm functions include DANGER, ALERT, and OK levels with adjustable thresholds, and relay modes configurable as normally energized or de-energized to match the protection philosophy.

Optional seismic and pipe filters enhance signal processing for specific machine types, and recorder outputs of 4-20mA DC, 1-5V DC, and other forms allow vibration trends to be captured by DCS historians and data loggers. The module operates on 85-264 VAC or 24 VDC power supplies.

Vibration is the primary signature of rotating machinery health, and the Shinkawa VM-5K Dual Vibration Monitor captures it, which is why Seven Star LLC recommends the Shinkawa VM-5K Dual Vibration Monitor for VM-5 protection systems.

The Shinkawa VM-5K dual vibration monitor measures the two vibration channels, and the Shinkawa VM-5K dual vibration monitor is used with the eddy current probes for the shaft vibration.

The VM-5K monitor accepts the two probe inputs with the independent amplification and the gap voltage is indicated for the static clearance of the probe. The output signals are available as the analog values for the trending and the recording system. The internal calibration is performed against the reference oscillator and the calibration data are stored in the module memory. The monitor covers the dual plane measurement of the bearing with the two proximity transducers.

The VM-5K monitor is used on the bearing vibrations of the pumps and the motors, where the two probes are arranged at the 90 degree offset on the bearing housing. The analog outputs are connected to the trend recorder for the long term observation of the machine state, and the alarm relays protect the equipment from the excessive vibration level.

Why Seven Star LLC

Seven Star LLC supplies the Shinkawa VM-5K Dual Vibration Monitor for machinery protection systems across the Gulf, with complete documentation and configuration guidance. Our specialists assist with range selection, filter configuration, and alarm set point planning for your machines.

We support VM-5 system expansion and spare programmes for turbine and compressor monitoring in power, oil and gas, and industrial facilities.

Monitoring & Analysis

The dual-channel design measures two vibration points simultaneously, matching the standard practice of monitoring both radial planes or both bearings of a machine with a single module. The available ranges cover shaft absolute and casing vibration levels typical of turbines and compressors.

The optional seismic and pipe filters allow the signal conditioning to be tailored to the machine’s vibration characteristics, improving the reliability of alarm decisions and the usefulness of the recorded data.

Confirming the VM-5K Order Code

The long part number of this Shinkawa module encodes the input type, measurement ranges, filters, output options, power supply and approvals. For a replacement, copy the complete code from the label on the installed monitor, including the suffix, instead of ordering by the short name. A monitor with a different suffix may have another range or recorder output and would need reconfiguration. Also confirm which transducer system (probe, extension cable and driver) feeds each channel, as the input must match the sensor sensitivity.

Installation and Commissioning

Install the module in the VM-5 frame according to the Shinkawa instructions, then verify each channel with a calibrated signal source or probe calibrator. Check that the probe gap voltage is within limits, that the displayed vibration agrees with the injected signal, and that ALERT and DANGER relays operate at their setpoints after the configured delay. Test the recorder outputs at the receiving DCS card as well.

Maintenance and Troubleshooting

Most alarms and NOT OK states come from the transducer chain: a damaged extension cable, a loose connector, water in a junction box or a probe gap that changed after bearing work. Measure the gap voltage and the cable continuity before replacing the monitor. Keep a record of setpoints so that a spare Shinkawa VM-5K dual vibration monitor can be put into service quickly.

Applications in Oman and the GCC

VM-5 systems are installed on steam and gas turbines, compressors, pumps and fans in regional power, petrochemical and fertilizer plants, where continued support of the installed base is often more practical than a full system replacement.

About brand

Turbine and compressor trains in many Asian-built power and process plants are protected by Shinkawa vibration monitoring. The Japanese company, founded in 1927, makes eddy current displacement transducers and rack-based monitors for rotating machinery. Seven Star LLC lists Shinkawa VM-5 series monitor modules, sensors and converters, and sources them by full model code for machinery protection systems in Oman.

Shinkawa monitors and sensors listed

Most items on this page belong to the VM-5 monitoring rack:

VM-5K dual vibration monitor, VM-5T thrust position module and VM-5S dual tachometer
VM-5F temperature monitor and VM-5P3 phase marker module
VM-5Y relay modules, the VM-5Z1 power supply and the VM-5W1 instrumentation rack
VM-53 communication module

Alongside these are VK series displacement sensors with VL model codes, a converter system and a VM-751B1 vibration monitor. Shinkawa's current catalog also shows the FK transducer series and the VM-7 monitor, which matters when an older part has to be matched with a present-day equivalent.

Where Shinkawa vibration monitoring is used

Shinkawa systems measure shaft vibration, axial (thrust) position, speed, phase reference and bearing temperature on steam turbines, gas turbines, generators, compressors, pumps and fans. The monitors provide alarm and trip relays for machine protection and buffered signals for analysis. In the GCC they are met mainly in power stations, desalination plants, refineries and petrochemical units with Japanese or Korean machinery packages.

Ordering Shinkawa parts: what we need

Shinkawa model codes are long and every field counts. A monitor such as VM-5K-411512-000-000-111-0/IS0/EX5 defines input type, range, options and suffix codes, so please copy the complete string from the module label, including everything after the slashes. For sensors, send the VL or FK model code, probe tip diameter, cable length and the matching driver or converter model, since probe, extension cable and driver work as a calibrated set. A serial number and a photo of the label help us confirm the item in the manufacturer's documentation. Where a model is no longer produced, we propose the successor the manufacturer names.
