Atec Emerson-CSI-2140 - Manual (Page 5)

Full Range of Measurement - The CSI 2140 sets the industry
bar with its exceptional frequency range. The CSI 2140 can
accurately measure signals on critical low speed equipment
that would be out of range for other vibration analyzers/
collectors. The CSI 2140 also boasts the highest frequency
range in the market. It can measure signals up to 80,000 Hz,
critical for accurate diagnosis of centrifugal compressors and
other high speed machinery.
In-Field Analysis - When your reliability goals require more
advanced care of your equipment and the diagnosis of complex
machine faults than standard route spectrum and waveform
data can provide, you need a vibration analyzer with advanced
analysis tools. The CSI 2140 delivers advanced in-field analysis
tools, including:
n Waveform autocorrelation for distinguishing between
periodic impacting from bearings and gears versus random
impacting associated with lubrication issues.
n Fault frequency overlays to match and identify the specific
source of energy peaks in the vibration spectrum
n Trending of up to 12 narrow band parameters for as long
as two years, allowing you to see where on the trend your
immediate measurement acquisition appears as compared
to previous data
n
Fourteen predefined analysis experts (such as coast down,
bump tests, time synchronous averaging, order tracking,
MCSA, high resolution, high frequency, etc.) for
troubleshooting difficult machine problems
n
View up to 8 plots for comparisons of multiple measurements
Variable Speed Analysis - Variable speed analysis is essential
to any effective machinery health program because many
critical pieces of equipment are operated at varying speeds
to accommodate the changing production demands. While
most vibration systems do not take variable speed into account
during data collection, the CSI 2140 automatically adapts its
diagnostic tools to variable turning speeds during routine data
collection. This helps eliminate data blur/smear and provides
an accurate trend for evaluation of developing problems in the
field.
Predict Catastrophic Failure of Sleeve Bearings - Many online
monitoring systems installed in plants today serve as nothing
more than a shutdown switch in the case of a catastrophic
condition. By collecting the signals from these systems with
the CSI 2140, you can add predictive capabilities by identifying
faults before a major issue occurs. Four-channel data collection
allows for the simultaneous monitoring of orbit plots from both
of the bearings on sleeve bearing equipment. These orbit plots
can identify problems such as oil whirl/oil whip, misalignment
and shaft rubs. Trending data can uncover developing cracks
and other types of structural faults.
Monitoring Problem Machines - The CSI 2140 can also
serve as a temporary online monitor. With line power, you can
continuously monitor machine health for up to a month. The
CSI 2140 can automatically acquire and store data, including
overall vibration, fault frequency bands associated with specific
fault types, or even the complete spectrum over an extended
period of time. Capture the break-in period for new equipment
or ensure that a machine with a known fault can make it to the
next outage.
Capture Machine Startups/Shutdowns - For analysis of
transient events, the CSI 2140 collects a continuous waveform
that can have specific data extractions during startup, coast-
down, or process changes. Spectra extracted from the transient
waveform can be viewed individually or in a Cascade plot to
show changes with speed and time. This analysis can be very
useful for identifying critical and resonant frequencies for turbo
machinery.
Correlate Vibration and Process Variables – The CSI 2140
has the ability to measure, store, and trend process variables
associated with equipment in addition to the equipment
vibration signals. The process variables such as pressure,
temperature, speed, flow, etc. can either be measured through
the voltage inputs or manually entered via the touch screen
user interface. These process variables can be correlated with
vibration to provide information about the health of the
machine or help determine root cause operational conditions
for the machinery health.
