Atec Emerson-CSI-2140 - Manual (Page 6)

Modular Design to Match Your Needs
The CSI 2140 can be configured to specifically address your
current needs – and is modular to expand as your needs change
in the future. Easily and affordably expand your capabilities
while protecting your initial investment. This versatile unit can
be purchased as a single-, dual-, or 4-channel analyzer – with or
without route measurement capability or as a dedicated field
balancer. Put together any combination of capabilities to match
your requirements. Additional modules are also available for
transient and structural analysis.
Advanced Cross-Channel Analysis - Standard data
collection serves as an excellent base for identifying
developing machinery faults, but cross-channel analysis is
often required to identify the root cause of the fault. In
addition to regular data collection, the advanced cross-channel
application also measures coherence and transfer functions
between the measured channels. Cross-channel analysis
enhances the vibration data by helping to determine the
actual movement of the shaft during operation and identifying
structural faults such as cracks and resonance. Cross-Channel
data is typically collected between a reference sensor and up
to three other sensors, and full transfer function, phase and
coherence data is available with every channel.
Operating Deflection Shape (ODS) Modal Analysis – ODS
data allows for a structural modeling of a machine that is then
animated using actual operating vibration data. Analysts can
observe visually how the machine is moving during operation,
and could identify the need for a structural correction. Data is
collected while the machine is running and shows motion due
to a combination of structural resonances (typically seen in
modal analysis) and operational forces such as misalignment or
imbalance. Using four-channel data collection is a non-intrusive
means for easily capturing all the necessary data without
interrupting production. The pairing of a triaxial and regular
single axis accelerometer combined with simultaneous
4-channel collection can make the ODS data acquisition
simple and efficient.
Transient Analysis - The Advanced Transient Analysis
application allows you to record the raw vibration signal over
a prolonged period of time for post-processing and analysis.
This is essential for diagnostics of turbomachinery startup and
coastdown or machines with short, repetitive duty cycles.
Unlike other offerings the CSI 2140 captures transient
waveform data as a single continuous block of data and not
multiple shorter data blocks that are then pieced together in
the software. This continuous waveform data ensures that
nothing is missed in the collection or diagnosis. This data can
be examined directly on the CSI 2140 or even replayed live in
AMS Machinery Manager.
Field Balancing - The Advanced Balancing application
allows you to use the CSI 2140 as a field balancer. This
application combines advanced technology with simple,
straightforward operation for a fast, effective solution to your
balancing problems. The graphical user interface automatically
guides you through the balance checklist so only minimal
training is required for effective operation. The application
offers a basic mode for simpler machine trains and an advanced
balancing mode with up to 4-planes for longer more complex
machine trains. Full job documentation can be printed or
stored in AMS Machinery Manager.

The triaxial accelerometer collects data at the measurement
location from a vertical, horizontal, and axial directions
simultaneously.
