Applications information

The VSV301 monitoring module is ideal for

monitoring, protecting, analysing and diagnosing

critical assets such as gas turbines, steam turbines,

hydro turbines and other rotating machines. A

VSV301 can be used as a stand-alone module or

as part of a more comprehensive monitoring

system operating with a VibroSight Server (and

data repository).

VibroSmart® systems (VSV30x + VSB300,

VSI010 + VSB010 and VSN010) conform to the

IEC 61850-3 requirements for power plant and

utility applications – when installed in specific

configurations. Contact Meggitt SA and/or refer

to the VibroSmart® distributed monitoring system

(DMS) hardware manual for further information.

For specific applications and other information,

contact your local Meggitt representative.

In addition, the VibroSmart Tools edition of

VibroSight is a special reduced functionality

(lower cost) version of the software with a

simplified user interface that is intended for use

with VibroSmart systems only. This edition is

capable of handling live data for static

measurements directly from VibroSmart system

(that is, it is not possible to connect to a VibroSight

Server).

Refer to the VibroSight® machinery monitoring

system software data sheet for further information.

 For example, measurements (dynamic or static) can

be logged to a VibroSight Server data repository

and/or displayed in the VibroSight Vision software.

The VibroSight Vision plot catalogue includes

static plots such as Bar chart, Spider, Table, Trend,

Bode, Polar, Correlation and Shaft Centerline,

and dynamic plots such as Waveform, Long

Waveform, Polar Waveform, Orbit, Corbit,

Spectrum and Full Spectrum, Waterfall/Cascade,

and Full Waterfall/Cascade.

Software

The VibroSight software supports the

configuration and operation of VibroSmart

modules, including the storage, display and/or

further processing of VSV30x data for analysis. For

example, measurements (dynamic or static) can

be logged to a VibroSight Server data repository

and/or displayed in the VibroSight Vision software.

The VibroSight Vision plot catalogue includes

static plots such as Bar chart, Spider, Table, Trend,

Bode, Polar, Correlation and Shaft Centerline,

and dynamic plots such as Waveform, Long

Waveform, Polar Waveform, Orbit, Corbit,

Spectrum and Full Spectrum, Waterfall/Cascade,

and Full Waterfall/Cascade.

Security

The VSV301 + VSB300 support a module lock

feature that can be used to limit the functionality

of a VibroSmart® distributed monitoring system

(DMS), as required. Enabling module lock, for a

module, measurement block or system, helps to

reduce the possibility of interference in the

operation of the monitoring system itself and in

the machinery being monitored.

Accordingly, VibroSmart® security (module lock)

makes it easier for operators to comply with

international security / critical infrastructure

regulations. Refer to the VibroSmart® distributed

monitoring system (DMS) hardware manual for

further information.

VibroSmart modules that are located side-by-side

can communicate directly (no Ethernet cabling

required) using the sidebus connectors on the

terminal base that support both SBUS and

redundant power supply distribution. VibroSmart

modules that are mounted separate from one

another can communicate over standard and

redundant Ethernet networks of shielded twistedpair

Ethernet cable using the Ethernet connectors

on the terminal base. However, using these

Ethernet connectors does require that the power

supply is distributed separately.

Discrete signal interface (DSI) inputs, including the

module lock signal, and tachometer signals can

be connected directly to individual modules

(locally). Alternatively, to reduce external wiring,

these signals can be connected to a single

VibroSmart module and shared among modules

in the same measurement block using the SBUS.

Communications

All VibroSmart modules and devices

communicate using a system bus (SBUS), based

on Ethernet technology, that supports data

transfer rates of 100 Mbps at distances up to

100 m. The SBUS ensures the transfer of both nonreal-

time (standard) and real-time (time critical)

information between VibroSmart modules, and

supports communication with the host computer

running the VibroSight software.

VibroSmart modules can either be located sideby-

side (adjacent to each other) or separate

from one another. This flexibility allows the

functionality of the monitoring system to be

distributed depending on the size of and access

to the machinery being monitored. It also helps

reduce the expensive sensor cabling typically

required between sensors and monitoring

modules, by effectively replacing it with lower

cost Ethernet and power supply cabling.

DESCRIPTION

Introduction

The VibroSmart® distributed monitoring system

(DMS) is a system of modular and scalable

products designed for condition monitoring and

machinery protection applications for power

generation turbines, oil and gas applications and

auxiliary balance-of-plant equipment.

VibroSmart® modules can be mounted directly

on machinery, reducing the need for expensive

cabling, because they are designed and certified

to work in extremes, such as harsh industrial

environments characterized by potentially

explosive atmospheres (Ex Zone 2), high

temperatures (70°C, 158°F) and high mechanical

stress. VibroSmart® complements the VM600 series

of rack-based solutions from Meggitt’s

vibro-meter® product line and is compatible with

the same VibroSight® machinery monitoring

system software.

The VibroSmart® VSV301 monitoring module has

two independent dynamic vibration channels

and one auxiliary channel, that can be

configured as either a tachometer or a DC input

channel. The VSV301 module is capable of standalone

vibration monitoring or can be integrated

with other VibroSmart modules to create a larger

system with more measurement channels and features.

Different versions of the VSV30x module

Two different versions of VibroSmart VSV30x

monitoring module are available: the VSV301 and

the VSV300.

• For the VSV301, the dynamic channel buffered

outputs are buffered (output-to-input ratio of 1:1)

and a VSA301 buffered output amplifier is only

required for signal transmission over long

distances (up to 500 m).

• For the VSV300, the dynamic channel buffered

outputs are attenuated (output-to-input ratio of

1:10) and require a VSA301 buffered output

amplifier to make the “raw” sensor signals

available at their original amplitude.

Apart from the transfer ratio (dynamic channel

buffered outputs described above) and

measurement phase accuracy (see Buffered

outputs – dynamic channels on page 9), and

maximum operating temperature

(see Environmental on page 11), the VSV301 and

VSV300 are the same, and both use the same

VSB300 terminal base
