VSA003 BNC cable assembly

The VSA003 BNC cable assembly is designed to

connect the buffered sensor “raw” outputs

available from VSV30x + VSB300 monitoring

modules to other systems.

The VSA003 uses a 2 m long cable, one end of

which is terminated with flying leads crimped with

wire-end ferrules for easy connection to a

VSV30x + VSB300 module (via the terminal base’s

J2 connector). The other end of the cable is

terminated with female BNC connectors for use

with patch panels such as the VSA004 BNC patch panel.

As each populated VSA004 BNC patch panel slot

uses a VSA003 BNC cable assembly to connect to

a VSV30x + VSB300 module, one VSA003 is

automatically included for each populated

panel slot in an order, although they can also be

ordered separately.

For specific applications and other information,

contact your local Meggitt representative.

More specifically, VSA003 BNC cable assemblies

and VSA004 BNC patch panels make the

buffered sensor “raw” outputs from

VSV30x + VSB300 monitoring modules available

via BNC connectors in a rack, panel or other

enclosure in order to allow test and measurement

equipment to be more easily connected to these

VibroSmart module signals.

VibroSmart distributed monitoring system

A VibroSmart® distributed monitoring system

(DMS) is a network of small and economical

modules providing measurement,

communications or other functions that are

connected together in distributed, networked

measurement blocks in order to provide the

functionality normally offered by rack-based

machinery monitoring systems. A VibroSmart

system consists of one or more measurement

blocks, each containing up to sixteen VibroSmart

modules, such as VSV30x + VSB300 monitoring

modules, a power supply and an optional host

computer running the VibroSight® software.

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, eliminating the need for costly

cabling, because it is 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

VM600Mk2/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® VSA00x BNC cable assemblies

and BNC patch panels are accessories designed

for operation with VibroSmart VSV30x + VSB300

monitoring modules. The VSA003 is a BNC cable

assembly while the VSA004 is a BNC patch panel.

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

A VibroSmart module consists of an electronics

module (providing configurable machinery

monitoring functions) that clips into a VibroSmart

terminal base, which mounts on a DIN rail.

VibroSmart terminal bases incorporate buses and

connectors to provide all of the I/O connections

required to interface to a VibroSmart module.

Terminal bases also include non-volatile memory

to store the configuration of the attached

VibroSmart module, which allows modules to be

hot-swapped. Modules and terminal bases use

mechanical key-coding for a system that is simple

to operate and use.

Different VibroSmart modules, terminal bases and

fieldbus communications adaptors can be

combined to offer unique combinations of

functionality, versatility and safety assurance. 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.

VibroSmart distributed monitoring system

A VibroSmart® distributed monitoring system

(DMS) is a network of small and economical

modules providing measurement,

communications or other functions that are

connected together in distributed, networked

measurement blocks in order to provide the

functionality normally offered by rack-based

machinery monitoring systems. A VibroSmart

system consists of one or more measurement

blocks, each containing up to sixteen VibroSmart

modules, a power supply and an optional host

computer running the VibroSight software.

A measurement block is a logical grouping of

VibroSmart modules that allows data such as

tachometer, trigger and alarm information to be

shared, for example, in order to monitor the same

machine. Measurement blocks are configured

using the VibroSight® software.

Note: A VibroSmart system is limited to a

maximum of sixteen VSV30x modules per

measurement block and a maximum of eight

measurement blocks without VibroSmart VSN010

real-time Ethernet switches. However, if each

measurement block contains a VSN010, then a

higher number of measurement blocks can be

achieved, limited only by overall system

performance (network traffic, VibroSight

computer configuration and so on).

APPLICATIONS

• Vibration and/or combustion monitoring

• Machinery protection and/or

condition monitoring

• Conforms to IEC 61850-3 requirements for

power plant and utility applications
