Shinkawa VM-5W1 Dual Power Instrumentation Rack

Name: shinkawa vm-5w1 dual power instrumentation rack – Datasheet
Brand: Shinkawa

Description

Overview

The Shinkawa VM-5W1 dual power instrumentation rack is a dual-power-supply rack within the Shinkawa VM-5 series of machinery protection monitors, built to house up to ten monitor units for continuous vibration, displacement, and process-parameter monitoring on critical rotating equipment. It is specified by turbine, compressor, and pump operators across Oman and the GCC who need a redundant, rack-based monitoring platform for turbines, compressors, generators, and other high-value rotating machinery.

The “W1” designation reflects its defining feature: the rack accepts two VM-5Z power supply units operating in redundant configuration, so a single power-supply failure does not interrupt protection of the machine train it monitors — a requirement standard on turbine and compressor trains where continuous vibration surveillance is a safety-critical function.

Operating Principle

Individual monitor units installed in the VM-5W1 rack accept signals from eddy-current (FK/VK), casing vibration (CV/CA), LVDT, and speed (RD-series) transducers, processing them into continuous measurements of shaft vibration, displacement, acceleration, eccentricity, differential expansion, rotational speed, temperature, thrust position, and valve position depending on the modules installed. Each monitor unit outputs both a proportional analog signal — 1 to 5 VDC (250Ω impedance) or 4 to 20 mA DC (500Ω max load) — and two recorder outputs, feeding plant DCS and recording systems continuously.

Engineering Design of the Shinkawa VM-5W1

The rack is built in a standard 19-inch form factor with front-panel monitor displays for at-a-glance readings and rear-panel installation of relay, communication, and power modules. Each VM-5Z power supply accepts 85 to 264 VAC at 48 to 64 Hz, with VM-5Z1/4 units drawing up to 265 VA and the VM-5Z2 variant up to 135 W; an optional VM-5Z0 backup module can sustain full load for up to 0.2 seconds during a power interruption, bridging brief power events without a monitoring gap. Each monitor position provides eight relay points (H-DANGER1, H-ALERT1, L-ALERT1, L-DANGER1 and the equivalent set for a second channel) rated 250 VAC/5A or 30 VDC/5A for alarm and trip signaling.

Industrial Applications

Across Muscat, Sohar, and Salalah, the VM-5W1 rack is deployed on steam and gas turbines, compressor trains, and large motor-driven equipment in power generation, LNG, and petrochemical facilities, where continuous, redundant vibration and process monitoring is required for both machinery protection and predictive maintenance programs. Its ability to house up to ten monitor units in one rack makes it practical for monitoring multiple bearings and parameters on a single large machine train from a centralized panel.

The rack’s redundant power design also supports critical unspared equipment such as main boiler feed pumps and generator sets, where an unplanned monitoring gap during a power-supply fault is not an acceptable risk, and its DCS-compatible analog and recorder outputs integrate directly into existing plant control and historian systems.

Shinkawa's current catalog also shows the FK transducer series and the VM-7 monitor. This matters when an older part has to be matched with a present-day equivalent.

How a Shinkawa protection chain works

An eddy current probe sits a set distance from the shaft. Its driver (converter) turns the gap into a voltage, and the monitor turns that voltage into vibration, thrust position or speed values with alert and danger set points. The probe, extension cable and driver are calibrated together for one total system length and one target material, usually AISI 4140 shaft steel. Changing one part without matching the other two shifts the calibration. The monitor relays feed the turbine or compressor trip logic, and buffered outputs go to analysis systems. Many protection systems of this kind are specified to API 670.

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. In the GCC they are found 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 code such as VM-5K-411512-000-000-111-0/IS0/EX5 defines the input type, range, options and suffix codes, so 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 the 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.
