Meggitt VibroSmart® Distributed Monitoring System (DMS)

What is VibroSmart DMS?

The VibroSmart® DMS (distributed monitoring system) 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 DMS modules can be mounted directly on machinery, eliminating the need for

costly cabling, because VibroSmart is designed and certified to work in extremes, such as

harsh industrial environments characterised by potentially explosive atmospheres (ATEX

Zone 2), high temperatures (70°C) and high mechanical stress. VibroSmart complements the

VM600 series of rack-based solutions from Meggitt Sensing Systems' Vibro-Meter ® product

line and is compatible with the same VibroSight ® software.

A VibroSmart DMS is a network of small and economical devices providing different

monitoring system functions (for example, measurement or communications) that are

connected together in one or more measurement blocks in order to provide the functionality

normally offered by rack-based machinery monitoring systems.

In general, a VibroSmart DMS can contain up to 8 measurement blocks and each

measurement block can contain up to 16 VibroSmart modules. For example, this allows a

VibroSmart DMS using VSV300 vibration monitoring modules (two dynamic input channels

and one auxiliary input channel) to be built that provides a monitoring system with between

1 and 384 input channels (256 dynamic and 128 auxiliary/tachometer).

The actual functionality provided by a VibroSmart DMS depends on how the constituent

measurement blocks and VibroSmart DMS modules are configured, which is done using the

VibroSight® software.

Simplicity and ease of use

The VibroSmart DMS has been designed to be simple to install and use, with special care

taken for the handling and maintenance aspects of the system:

• A VibroSmart DMS can be installed in a short amount of time by a qualified electrician.

• Installation of a VibroSmart DMS, individual modules and the connection of signals is

performed using standard tools.

• VibroSmart DMS modules are "hot-swappable" and can be installed or replaced in

seconds.

• All VibroSmart devices are DIN rail mountable.

• Different configurations (network topologies) are supported: linear and redundant

HSR ring.

Applications

VibroSmart is a cost-effective family of devices that offers unique combinations of

functionality, versatility and safety assurance. Different VibroSmart modules, terminal bases,

devices and communications adaptors can be combined to build any machinery monitoring

system. In this way, a monitoring system can be built to meet the exact needs of an

application resulting in a more cost-effective and reliable solution.

In practice, a VibroSmart DMS consists of one or more VibroSmart modules connected

together in one or more measurement blocks in order to provide a machinery monitoring

system. The actual functionality provided by a VibroSmart DMS depends on how the DMS is

configured, which is done using the VibroSight® software.

ypically, a VibroSmart DMS can be configured and operated as a machinery protection

system (MPS), a condition monitoring system (CMS) or a combined MPS/CMS:

• An MPS can be implemented using a VibroSmart DMS configured without a VibroSight

Server and database, that is, a simple "stand-alone" DMS.

• A CMS must be implemented using a VibroSmart DMS configured with a VibroSight

Server and database in order to allow the permanent storage of data for viewing at a later

time.

VibroSmart DMSs are intended primarily for vibration monitoring of critical assets such as gas

or steam turbines, motors, compressors, generators, feed pumps, fans or other rotating and

reciprocating equipment in the power generation, petro-chemical and petroleum industries.

The modular and scalable nature of VibroSmart DMS means it can also be used to provide a

versatile and cost-effective monitoring system for balance of plant equipment.
