Overview
The rugged CSI 9420 Wireless Vibration Transmitter is the
first device to provide full vibration data over a self-organizing
wireless network. It provides rich information about machinery
health for both operations and maintenance personnel. Overall
vibration, PeakVue, and temperature readings can be easily
integrated into any control system or plant historian while diagnostic data can be displayed by AMS Suite: Intelligent
Device Manager or any EDDL compliant host. For advanced
diagnostics, high resolution data can be delivered to AMS Suite:
Machinery Health Manager for trending and analysis.
The CSI 9420 delivers complete vibration information, including
high resolution spectra and waveform, over a self-organizing
wireless network for use by operations and maintenance personnel.
Cost-Effective, Reliable Monitoring
The CSI 9420 extends vibration monitoring to an entire
array of new applications. While appropriate for most
vibration monitoring tasks, it is especially well suited for
hard-to-reach locations, such as cooling towers, pumping
stations, remote equipment, and hazardous areas.
In general, the CSI 9420 provides an excellent solution for any application that might otherwise involve
extensive engineering, cabling, or installation costs.
Advanced electronics deliver a high level of accuracy,
while the IEC-approved WirelessHART standard delivers
exceptional reliability.

Overall Condition in the Control Room
Diagnostic Data to the Maintenance Office
The CSI 9420 delivers information about the overall health of
rotating assets directly to the control room via Modbus or OPC.
Overall vibration data is a good indicator of shaft problems
such as imbalance, misalignment, or mechanical looseness.
In contrast, the PeakVue reading provides a reliable measure
of impacting on the machine. As the PeakVue level increases,
it provides direct indication of a developing problem, such as
improper lubrication, bearing fault, or gear defect. Process
induced faults, such as pump cavitation, are detected by an
increase in both the overall vibration and PeakVue readings.
AMS Machinery Manager automatically communicates detailed
diagnostic data to the maintenance office, including overall
values, energy bands, high resolution spectra, and waveforms.
Once stored in the AMS Machinery Manager database, these
measurements deliver the same diagnostic value as comparable
readings collected using Emerson’s industry- leading CSI 2140
Machinery Health Analyzer.
Asset Dashboard at your Fingertips
AMS Device Manager generates an asset dashboard based on
the output of the CSI 9420. This intuitive interface displays the
health of the sensor, the transmitter, and the production asset
being monitored – extending the benefits of PlantWeb® to WirelessHART devices.
AMS Machinery Manager provides advanced analytical tools
to trend vibration levels, generate alerts, and diagnose
developing faults.
Information Available When You Need It
There are now three ways to collect high-resolution spectra
or waveforms:
1) Time-based: Collect readings automatically on a scheduled
basis, i.e. once every two weeks.
2) On-alert: Collect readings automatically whenever an alert
is registered based on either the overall vibration or the
PeakVue impacting.
3) On-demand: Manually initiate a reading at any point when
current diagnostic data is required.
This allows you to quickly and easily access current health
information about your rotating assets without leaving
your desk.
AMS Device Manager uses EDDL technology to create an asset
dashboard with clear indication of device and asset status.
AMS Machinery Manager provides advanced analytical tools
to trend vibration levels, generate alerts, and diagnose
developing faults.

Flexible Configuration Options
Wireless Architecture Overview
The Power to Get Things Done
Ultimate Simplicity
There are two power options for the CSI 9420. For a truly
wireless experience, utilize the SmartPower™ Module. Based on
the low power output defined by the WirelessHART standard,
the CSI 9420 can achieve an operating life of up to 4 years when
using the Power Save option. An operating life of two to three
years can be achieved when using the default settings (update
rate set to 60 minutes).
Built on the IEC 62591 (WirelessHART) industrial standard, Emerson’s wireless network is completely self-organizing. There is no need to configure communication paths because
the Smart Wireless Gateway manages this automatically – including adapting to changing environments. Once the network is established, new devices can be added at any time. Conversely, even if a device is de-commissioned,
data reporting from other devices continues uninterrupted
over other established paths.
For faster update rates, the external DC-powered terminal block is recommended. This option provides virtually
unlimited operation, even at the minimum update rate
of once per minute.
Local Indication and Verification
The optional LCD display provides a local read-out of
sensor values and transmitter diagnostics to streamline commissioning and troubleshooting at the device. Local indication of vibration measurements and diagnostics
also provides accurate, real-time verification of operating conditions. The LCD display can be rotated to facilitate easy
viewing, regardless of the orientation of the transmitter.
Plan and Manage Wireless Networks
The AMS Wireless SNAP-ON™ application is a revolutionary
tool that enables you to both plan and manage your wireless
network. Starting with a scale drawing of the plant, utilize
simple click-and-drag functionality to position the gateways and wireless devices. Then the AMS Wireless
SNAP-ON application will compare the plan to industry
best practices. Recommendations will help you quickly
develop a reliable wireless network.
Easy Installation
The CSI 9420, like all Emerson’s Smart Wireless transmitters,
is simple to install. As soon as power is applied to the device,
it will automatically establish communication with neighboring
wireless devices, establish a path to the Gateway, and begin
reporting. Each transmitter also has the ability to function as
a repeater, relaying data from other devices to extend the network across virtually any size facility or industrial campus.
Network Stability
The Smart Wireless Gateway connects the wireless network
with the host system and data applications like AMS Suite.
The Gateway manages all aspects of the network: executing
scheduled readings and accommodating requests for on-
demand acquisitions. The Gateway configures the network
to minimize power consumption and ensure network stability,
while maintaining data reliability well above 99%.
After the devices are installed, the AMS Wireless SNAP-ON application will help you manage the network, providing
a graphical overview of the communication paths and
network health.

Best-in-Class Security
Analyze Data in AMS Machinery Manager
Emerson’s multi-layered approach to wireless network
security builds on the IEC 62591 standard to ensure that
your data stays protected – no matter what. Authentication
and verification make certain that only authorized devices
can join the network, while 128-bit encryption shields your
information. Channel hopping maintains operation, even in
challenging environments.
Vibration data from the CSI 9420 can be stored and analyzed
in AMS Machinery Manager. The Data Import module provides
easy data mapping using simple drag-and-drop commands.
AMS Machinery Manager combines predictive techniques with
comprehensive analysis tools for an accurate assessment of the
machinery health in your facility.
Emerson’s Complete Smart Wireless Solution
Emerson has a complete portfolio of Smart Wireless transmitters for many applications, including temperature,
pressure, flow, and level. In addition, the Smart Wireless THUM™
Adapter can enable any HART device to wirelessly transmit measurement and diagnostic information. Emerson wireless
devices can be accessed and maintained remotely using the
same tools and software as wired devices, leveraging existing
practices, training, and maintenance procedures.
Detailed Reliability Data
Overall vibration indicates when a machine is running rough,
while the level of impacting detected by PeakVue signal
processing provides the operator with an indication about
the presence and severity of a serious defect such as underlubrication, bearing faults, gear defects, and pump cavitation.
Furthermore, once a machine has been flagged, detailed data
can be analyzed by a vibration specialist to verify the exact
nature of the fault. With the advanced diagnostics in the
CSI 9420, you have easy access to all of this critical information.
High Resolution Waveform
The vibration waveform (shown below) is the basis for all
other vibration measurements performed by the CSI 9420.
Each waveform is a complex data set of thousands of samples,
collected over several seconds of machine operation.
While the acceleration waveform can be helpful in some applications, the PeakVue waveform is indispensable for
diagnosing developing bearing and gear defects. Because of
their large size, however, waveforms tend to be collected less
frequently. Emerson’s Smart Wireless solution employs several
data compression techniques to extract the information while
facilitating easier transmission over the network.
At the heart of Emerson’s Smart Wireless solution is the selforganizing network, featuring tight security, infinite configurability,
and data reliability that rivals wired systems.
Seamless Integration to Host Systems
Easily configure and broadcast measurements to Emerson’s
DeltaV™ and Ovation™ digital automation systems; use Ethernet
IP™ to connect to Allen-Bradley® controllers; or apply Modbus
or OPC to report data back to most other automation systems
and/or data historians.

The acceleration waveform contains raw vibration data that allows
you to diagnose the health of the asset.

High Resolution Spectrum
Energy Bands
The first compression technique is FFT analysis, which
transforms the vibration waveform into a frequency
spectrum (shown below). This spectrum not only reduces
the file size by over 60%, it also presents the frequency
information in a more readable format. The smaller data
set accelerates responsiveness of the system while reducing
power consumption.
As a final data compression technique, the CSI 9420
divides the spectrum into three predetermined energy bands
(as shown below). It then calculates the vibration energy within
each energy band and passes these values to AMS Machinery
Manager for trending and alerts.
The elevated peaks in this high resolution spectrum provide a clear
indication of mechanical looseness on the machine.
Band
Fault Types
Range
1
Rotor Vibration: Imbalance,
misalignment (also defects on
belt drives)
2–65 Hz
2
Rotor Harmonics: Looseness,
electrical faults, blade and
vane pass
65–300 Hz
3
High Frequency: Bearing and gear
defects, lubrication and cavitation
300–1000 Hz
Energy bands with frequency ranges. Optimized for a 4-pole motor
running between 1500 and 1800 RPM. Note: bands are fixed.
Thumbnail Spectrum
The thumbnail spectrum is derived from the same
waveform data. It contains the same frequency and amplitude
information as the high resolution spectrum, but the data set
has been compressed by an additional 98%. Now it is small
enough to transfer over the network in less than a second.
By dividing the spectrum into energy bands, we can isolate
frequencies associated with different categories of faults.
The elevated peaks are still clearly visible in the thumbnail spectrum
and indicate the presence of mechanical looseness.

By trending the values in AMS Machinery Manager and comparing them to appropriate alert levels, it is possible to
set up a system of intelligent alerts that not only inform you
when the machine condition is deteriorating, but also provide
information about the underlying cause of the problem.
The figure illustrates how vibration data can be used to
detect and diagnose a developing fault. Based on the increase in
overall vibration (black line), an alert would flag the machine as
having a potential fault – but with no indication at all about the
nature or severity of the fault.
The trend of overall vibration suggests that machine health is
deteriorating but without any indication as to the root cause. The
trend of the high frequency energy band provides further insight,
which can be confirmed by examining the thumbnail spectra.
6
The trend of the three energy bands shows that the readings
for rotor vibration (green) and rotor harmonics (blue) are stable,
while the readings for high frequency vibration (red) have
increased sharply. This would trigger a special alert for
the rotating equipment specialist in AMS Machinery Manager.
Examination of the thumbnail spectra (shown above the trend)
confirms that the fault is high frequency in nature. On-demand
acquisition of the PeakVue spectrum and waveform then provides conclusive insight into the specific nature of the
fault as well as its severity. Using the advanced diagnostics
in the CSI 9420 and AMS Machinery Manager, maintenance
personnel can often address and resolve an issue without it
ever registering as an alert in the control room.

Are You Wireless?
As any plant manager will tell you, you can’t improve something
if you can’t measure it. Improved access to information provides
the opportunity to reduce operating costs while improving
quality, throughput, and availability. Add to that the expanding
requirement to certify compliance with new environmental and safety standards. This all points to the need for increased
monitoring, yet many managers still believe that the costs outweigh the benefits.
With wired systems, that may have been the case; however,
wireless networks remove traditional barriers and redefine the cost equation. A wireless network can substantially reduce
engineering, material, and implementation costs, and those
cost savings are just the beginning.
Imagine what you can do with the additional information.
Wireless technology can reduce – if not eliminate – the “blind
spots” in your plant, while empowering mobile workers by providing needed information. The CSI 9420 provides
predictive diagnostics for your essential production assets
from virtually any location. The result is increased process
uptime, improved consistency, and reduced risk of abnormal
situations. As more and more plants are turning to wireless
solutions, the question is “Are You Wireless?”.
A CSI 9420 is an easy addition to any existing wireless network.
