SKF @ptitude Observer
Expert guided software and intelligent machine diagnostics
SKF @ptitude Observer is a core platform in a family of
reliability software applications that work together as
SKF @ptitude Monitoring Suite.
SKF @ptitude Observer is an expertguided software and intelligent
machine diagnostics for correct
assessment of machines and
processes. You get expert advice
without talking to the expert.
SKF @ptitude
decision support
Successful condition monitoring is
based on powerful and user-friendly
machine diagnostics software for data
management and analysis.
@ptitude Observer is internationally
recognized for its operator interface
and intelligent diagnostics functions.
New machines can easily be created
in the software by using the Expert
Guide. Frequency bands, resolution,
defect frequencies, machine
diagnosis set up, etc., are generated
The SKF @ptitude Observer software

well as long term history can easily be
In the System Overview, the status of
each of the system components is shown,
clearly displaying any system component
SKF @ptitude Observer
Expert guided software and intelligent machine diagnostics
Historical data is shown in powerful
trends, where one or more parameters
can automatically be displayed and
compared to time, such as RPM or process
parameters (power, temperature, water
level, etc.). Trends can also be live updated
every second.
Machine information
Mechanical data for each machine
monitored is stored in a machine
information database. Machine
components are connected to each other
by dragging and dropping components
such as shafts, bearings, gear wheels and
impellers, in order to build the machine.
For each component, relevant information
such as bearing code, number of gear
teeth and number of vanes, is stored.
Example of a SKF @ptitude Observer orbit.
Based on this information and the actual
shaft speed, all defect frequencies are
Orbit diagram
automatically calculated, and advanced diagnostic rules are
Using signals from two perpendicularly mounted
transducers, the shaft orbital movement can be animated.
Orbits can be performed using the raw signal as well as
filtered at a user defined frequency range.
Root cause analysis
Although some of the measurement devices are equipped
with automated advanced diagnosis, the software contains
a great variety of tools for advanced root cause analysis, for
Defect frequency display
Each machine part, and the interaction between parts, is
defined in the machine information database. Based on this
information all machine defect frequencies are automatically
calculated and can be easily displayed in the frequency
spectra by the user. In spectrum live mode the defect
frequencies are continuously updated based on the instant
shaft speed.
Digital Peak Enveloping (DPE) analysis
Digital Peak Enveloping represents a major advancement in
early detection of bearing faults and is superior to previous
techniques for bearing fault detection.
This is automatically displayed for each spectrum.
Vibration amplitude/phase can be trended as a function
of time, speed or any process parameter recorded. It
is possible to trend discrete frequencies (fixed or speed
following) with user selected number of harmonics, as well
as a user selected frequency range.
Machine diagnostic
Includes standard rules for the most common faults such
as unbalance, misalignment, various bearing faults, gear
faults, cavitation, etc. User defined diagnosis rules can easily
be designed. Machine diagnostic is automatically activated
by an alarm measurement. SKF @ptitude Observer
automatically performs frequency analysis and verifies type
of machine fault.
Historical comparison of data
Frequency spectra taken at different times can be displayed
and individually compared. Also subtraction of a selectable
measurement can be done. Selected reference spectra
may be fixed and automatically matched with new or earlier

Polar plot
Illustrates phase vs. amplitude including
alarm circles. Alarms are set for changes
in phase or amplitude outside preset limits.
Shaft centerline
Using signals from two perpendicularly
mounted transducers, the shaft radial
position is shown. The system allows
sensor mounting in any radial direction
with the two sensors 70 to 110 degrees
Run-up/coast-down (transient)
Example of a SKF @ptitude Observer process overview.
Harmonic analysis
With a user-defined frequency, harmonic frequencies can
be displayed. The system automatically calculates the best
fit for the harmonics, making harmonic effects much more
visible. This is often used together with defect frequencies.
Sideband analysis
With a user defined frequency band, sideband frequencies
can be displayed making sideband effects much more visible.
This is often used together with defect frequencies.
Turbine module
A fully integrated plug-in module to the SKF @ptitude
Observer software is available that detects eccentricity
change in coupling; blade failure; bearing instability; steam
whirl; rotor crack; rotor rubbing; temporary rotor bow; loose
bearing pedestal; inclined position of bearing; electrical
run-out; mechanical run-out; loose stator core in generator;
change of imbalance at shutdown; radial bearing damage;
interturn short circuit in generator rotor, etc.
3-D plot
A powerful tool that illustrates frequency spectra vs. speed
or time during run-up/coast-down. 3-D plot can be used
with any historical data.
Turbine run-up or coast-down is
automatically detected and a user
defined measurement procedure starts.
Measurements are taken at defined speed
changes and all data is stored in a runup/coast-down buffer. The data can be
viewed in a great variety of displays such
as 3-D, spectra, time waveform, bode,
polar, orbit and shaft centerline.
Alarms and warnings
There are two types of alarms – primary alarms (checked
typically every second) and secondary alarms (checked at
every event and at an interval selected by the user, typically
once a day).
Primary alarms are to detect DC measurement points for
both high and low alarms with two levels each. For DPE
and vibration measurement points, primary alarms perform
at four different frequencies, fixed or speed dependent
and one frequency range. All measurement values can be
exponentially averaged. Alarm conditions can be controlled
by speed and/or load.
Secondary alarms are performed by advanced machine
diagnostics, with sophisticated alarm conditions chosen
from an alarm condition library or created by the operator.
Secondary alarms make prognostics three months ahead. If
a primary alarm is triggered, secondary alarm diagnostics
are automatically performed.
For vibration measurements, both primary alarms and
secondary alarms can be calculated in acceleration, velocity
or displacement, regardless of sensor type.
SKF @ptitude Observer
Expert guided software and intelligent machine diagnostics
All alarms are transferred to the SKF @ptitude
Observer Monitor and stored in the database
together with corresponding measurement data.
The @ptitude Observer Monitor computer can be
equipped with relay cards containing 16 relays
each, fully programmable to show any type of
The SKF @ptitude Observer software has
the capability to store the evaluated data in a
Microsoft SQL Server™ or an Oracle® database.
Using the royalty free Microsoft SQL Server
Express or Oracle Express, the database size can
be up to four gigabytes. Using a full version of
Microsoft SQL Server or Oracle, the size is almost
All stored data is marked with identification
stating date and time for later use in
troubleshooting and trend analysis.
To study faults accurately and for correction
purposes, it may also be beneficial to store
other information than vibration values, e.g.,
active and reactive power (standard). Storing of
turbine guide vane position, water level, voltage,
temperature, etc. are optional.
Storage is made in the following form:
Trend storage
Saves evaluated data. The trend data consists
of different trend buffers storing data from once
every 10 seconds to once every week. A value
from the first trend buffer is also stored in the
archive buffer every tenth minute. All trend
buffers and the archive buffer are using FIFO
(first-in, first-out).
Spectra storage
At a user defined time interval and upon an event
(see below) vibration spectra are stored for each
of the following measurement points:
• vibration
• vibration, harmonic
• process FFT
SKF @ptitude Observer
Expert guided software and intelligent machine diagnostics
Event related storage
Measurement points can be grouped. When
an event occurs, based on data from one of
the group members, measurement data from
all group members is stored. Also, an alarm
is generated in the alarm list showing what
evaluation form caused the event. An event can
be an alarm or a change in process data.
Remote control
Since SKF @ptitude Observer is a full client/
server application, commercial remote products
can be used. The SKF @ptitude Observer Monitor
can be connected to the Internet through a
firewall and easily accessed from a Windowsbased computer anywhere having SKF @ptitude
Observer installed.
Also remote control products like Citrix®,
pcAnywhere™, Remote Desktop®, etc. are
Data communication using OPC
SKF @ptitude Observer can be connected to other
systems or devices through an OPC server using
the OPC standard communication protocol. Data
transmission (data publication) of trend data and
alarm information, as well as data reception (data
subscription) of process data is possible.
System integrity
An on-line condition monitoring system should
always be operating. If something happens
that interrupts the monitoring, the system must
be able to detect the fault and report it to the
operator. If possible the system itself should be
able to correct the fault and continue to operate.
Below is a description of the @ptitude Observer
system integrity:
• checks all sensor signals and report on failure
• a Watchdog looks after both the IMx/MasCon
units and the @ptitude Observer Monitor and
reports, then restarts upon failure
• easy for the operator to disable a measurement
point upon sensor failure
• system faults are stored in the database and
can be accessed by the operator, for example,
during system service
