Brüel & Kjær Vibro offers two
such new generation compact
monitors:
n
VC-6000 compact monitor
n
Newly released VC-1500
The versatile VC-6000 cm can be
configured in a number of ways
for many different applications
and includes variable bandpass
and vector measurements (mag-
nitude and phase). See the 2008
Spring-Summer issue of Uptime
for more information on this prod-
uct.
The second, and newly released
VC-1500 is a small DIN-rail
mounted unit that has on-board
trending, frequency analysis, and
post-mortem analysis! See the
next article for more information
on this product.
These new generation compact
monitors play a new and critical
role in online machine monitor-
ing, especially for the previously
mentioned applications. But this
"gap filling" role is only a compli-
mentary one. Traditional vibration
monitors with basic condition
monitoring capability are still
effectively used in numerous
applications, and by no means
have suddenly become obsolete
overnight. The traditional moni-
tors will continue to be used for
many BOP machines where
safety monitoring is the predomi-
nant strategy. Brüel & Kjær Vibro
offers several vibration monitors
with basic condition monitoring
functionality, such as the VC-920,
VC-1000 and VC-1100.

T
he information needed to help
make an accurate O&M decision
concerning the condition of the ma-
chine, the rate of deterioration and/or
what happened just before or imme-
diately after the machine tripped is
essential. This information is not avail-
able in traditional vibration monitors.
So where do you get it from? Here are
your choices:
n
Invest in a separate condition
monitoring system that offers
analysis techniques, trending and
remote monitoring capability. This
requires a capital invesment, plus
training, support and IT manage-
ment

Call for an engineer to come on-
site with a portable data analyzer

Why have condition monitoring capability in a
safety monitor? Vibration monitors have tradition-
ally provided an inexpensive and simple solution for
protecting balance-of-plant machines (BOP) such
as pumps, fans, compressors, motors and other
auxiliary machines. These instruments can reliably
protect a machine from a catastrophic failure, but
... do little else. If a machine has tripped, the Plant
Manager has to make a operations and mainte-
nance (O&M) decision to start it up again and see
if it can run to the next scheduled stop, or open up
the machine immediatly to see what is wrong. Re-
gardless of the decision, it will have the impact of
production downtime and/or maintenance costs.
