Shinkawa VM-701B/CS1/TB1 Vibration Monitor
Overview
The Shinkawa VM-701B/CS1/TB1 vibration monitor belongs to the Shinkawa VM series and is used for continuous vibration monitoring of rotating machinery such as turbines, compressors and pumps. Shinkawa Electric is a specialist in vibration monitoring, and its VM series condition monitors convert the signal from the vibration sensor into the alarm and trip outputs required by the protection system. The part number identifies the monitor configuration with the sensor, cable and terminal options for the installed system.
The VM-701B is part of the Shinkawa VM series of condition monitors, which convert the vibration sensor signal into alarm and trip functions for the protection of rotating machinery. The monitor is available with the sensor, the cables and the terminal configuration defined by the part number, forming a complete monitoring channel. The series is supported by Shinkawa with the outline drawings, the wiring diagrams and the discontinued products channel for the legacy models installed in plants.
Engineering and Design
The VM-701B receives the signal from the vibration sensor, conditions it and compares the measured level with the alarm setpoints. When the setpoint is exceeded, the monitor switches the alarm and trip relays, giving the machinery protection system a fast and repeatable response. The monitor output is also available as a DC signal for the recorder or the DCS input, so the same instrument serves protection and diagnostics.
The CS1 and TB1 suffixes in the part number define the cable and terminal block configuration for the specific installation, and Shinkawa supplies the monitor together with the matching sensor to form a complete channel. The monitors are designed for rack or panel mounting in the control room, with the field signal routed from the machine to the monitor input. Shinkawa publishes the outline drawings and wiring diagrams for the series, and the legacy VM models remain supported through the discontinued products channel.
The VM-701B channel is installed in the control room with the field wiring routed from the sensor on the bearing housing to the monitor input terminals. During commissioning the alarm and trip setpoints are adjusted to the protection philosophy of the machine train and the verification is recorded in the commissioning report. The relay outputs are wired into the protection circuit, and the DC output is connected to the recorder or the DCS input for continuous trending of the vibration level. The monitor is powered from the plant supply and the complete channel is tested with the simulated signal before the machine is started. Shinkawa publishes the outline drawings and the wiring diagrams for the VM series, and the legacy models are supported through the discontinued products channel with the original documentation. The spare channel is verified against the installed configuration before shipment, including the cable length and the terminal block arrangement defined by the part number. Plants that run a Shinkawa condition monitoring system keep the VM-701B as a drop-in spare, which shortens the repair time when a monitor channel fails. The monitor is built for continuous industrial plant service.

Why Seven Star LLC
Seven Star LLC supplies Shinkawa vibration monitoring equipment, including VM series monitors, to reliability and maintenance teams across Oman and the GCC. Every part number is checked before your order is confirmed, and our team verifies the monitor configuration and the matching sensor set for your machine train.
Because the VM-701B/CS1/TB1 configuration code is specific to a particular cable length and terminal block arrangement, we cross-check it against your existing installed channel rather than assuming a generic VM-701B matches your site, since a mismatched cable configuration can mean rewiring at the terminal strip that a correctly specified spare would have avoided. For plants running a mixed fleet of turbines, compressors and pumps under one Shinkawa monitoring system, we help plan channel spares around your maintenance stock so a single failed monitor does not leave a protection gap on a different machine type than the one the spare was originally intended for.
Spares Planning for Shinkawa VM Channels
Reliability teams managing a plant-wide Shinkawa condition monitoring system often standardize on a small number of VM series configurations to simplify spares stocking, and we support that approach by confirming which cable and terminal options are already common across your installed channels before recommending a replacement, so a new VM-701B genuinely fits the spares strategy your maintenance team has already built and documented, rather than adding a one-off variant that the maintenance team would then need to track separately going forward.

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.Browse Shinkawa products by category: Vibration.
