The VIBROCONTROL 1500 combines reliable safety mon-
itoring with advanced condition monitoring system capa-
bility and this is at a fraction of the cost of what is nor-
mally offered in a rack-based system. It accepts inputs
from two accelerometers and two temperature sensors
and provides overall vibration, temperature and bearing
condition measurements from each channel. In addition
to this, it also offers trending capability, frequency analy-
sis, post mortem analysis and remote monitoring capabil-
ity! All of this is packed in a small DIN-rail box measuring
90 x 75 x 115 mm. No expertise is needed to install, com-
mission or use this product!
a diagnosis. Several trips would
have to be made for creating a
trend. This method can't be used
for post mortem analysis.

Powerful safety monitoring
capability in a little box
The 2-channel VIBROCONTROL
1500 (VC-1500) was specifically de-
signed for monitoring casing vibration
(ISO 10816), rolling-element bear-
ing condition (vibration) and bearing
temperature on a number of different
kinds of BOP machines. There is an
Alert and Danger relay that is activat-
ed if the respective alarm limits are
violated for any of the three meas-
urements on any channels. There is
also an OK relay that monitors the
function of the instrument and sen-
sors. For DCS/SCADA interfacing,
there is a 4-20mA DC output for each
vibration channel. All setups and data
display is done on the front panel via
push buttons or remotely.
This is a lot of safety functionality for
a vibration monitor, but the VC-1500
can do more than just protect your
machines! It can also help protect
yourself from unecessary downtime.
Bearing condition
Early fault detection and diagnosis
of rolling element bearings cannot
be achieved through overall vibration
measurements. The VC-1500 offers
a special technique called the Bear-
ing Condition measurement, which
is based on an envelope spectrum in
the 500-5000 Hz frequency range. A
special calculation algorithm is made
on the incoming envelope spectra,
which is then factored by an auto-
matically generated "good condition"
reference value. This unitless result,
called the Bearing Condition value, is
"1" for a good condition bearing, and
increases over time for a deteriorat-
ing bearing. No diagnotic expert or
specialist is needed to work with this
advanced condition monitoring meas-
urement!
Trending
A vibration monitor with a local data-
base! There are not many of those
on the market! The VC-1500 au-
tomatically stores data for all three
measurement types (overall vibra-
tion, bearing condition and tempera-
ture) for each channel on its onboard
memory.
There are three types of buffer
resolutions that are stored for each
measurement on each channel (i.e.
8 hours, 10 days, 10 months). This
allows you to more easily identify
both short and long term trends of
a developing fault. An additional
