 ALL equipment must function at
optimal levels. A state of the art condition
monitoring device called
SWANguard can be
applied to insure peak
performance and to
maintain high availability.
Regardless of when
final failure occurs during
an assets life cycle, it
starts as small discrepancies
and progresses
to larger ones that result
in secondary damage,
unacceptable operating
conditions or even
catastrophic failure.
Traditional condition
monitoring techniques
such as vibration
analysis do not provide
a clear indication of problems until late in
the failure process, if at all, are complex and
costly and perform poorly with low-speed
machinery and in very noisy environments.
SWANguard offers a cost effective way
for monitoring the mechanical condition of
equipment for the purpose of early detection
of mechanical degradation and wear.
The patented SWANtech Stress Wave
Analysis technology (SWAN) is ideal for
applications where the equipment being
monitored is subject to changing operating
conditions. The SWANguard module uses
sound, rather than motion, to identify and
directly measure friction and mechanical
deterioration. Stress wave measurements,
provide a direct measurement of the friction
and wear, even early in a machines life cycle.
A single SWANguard module can
monitor one or more sets of equipment,
depending on their complexity. For simple devices, such as a small pump, a single
sensor may suffice. The SWANguard takes
continuous stress wave measurements and
computes an aggregate friction/wear value
called SWE (Stress Wave Energy).
This SWE value is a real-time indication
of the level of friction/wear being experienced
by the machine. By trending this
value over time it is possible to see when
mechanical degradation is beginning, when
actual damage occurs and when remaining
operating life is rapidly decreasing. SWE
can even identify lubrication problems and
operational factors that place high, or excessive,
stress and wear on the equipment.
.
SWANguard units are supported by a SWANserver at each plant site/facility. The SWANserver polls and collects stress wave data from the SWANguard units and maintains a history of these readings. The SWANserver can be interfaced with plant automation and data historian systems.
