Meggitt VibroSmart® VSV301 + VSB300 monitoring module Description

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).

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.

VSV301 monitoring module

The VSV301 monitoring module performs the data

acquisition and all of the signal processing

(filtering, analog-to-digital conversion, time and

frequency domain processing, and resampling)

required to produce processed outputs and

extracted data for physical output and data

presentation in VibroSight and VibroSight Scope.

This includes spectral band extractions,

advanced FFT analysis, trending and limit checks

(alarm and sensor OK), and run-up / run-down

acquisition.

In addition, the VSV301 module has four basic

and two advanced logic functions that can be

used to combine local alarm and status

information in order to drive the module’s relays.

This local information and the logic function

outputs can also be used as inputs to the basic

logic functions of a VSI010 communications

interface module in the same measurement

block.

Like all VibroSmart modules, the VSV301 module is

fully software configurable using the VibroSight

software. Using VibroSight Configurator, a module

can be configured to capture data continuously

at scheduled intervals or on the detection of an

alarm condition. In addition, spectral resolution,

frequency bandwidth, windowing function and

averaging are all fully configurable.

Using VibroSight Vision, an extensive catalogue of

plots is available for the visualisation and analysis

of measurement data.
