Monitoring features

Measurement data, as well as other relevant information is shown in user-friendly displays. Live data, updated every second*, as well as long term history can easily be displayed in many different formats. In the multi-level process overview window, live data and alarm indications are shown in descriptive control room display pictures for individual machines or groups of machines, easy for the operator to use.

* Depends on the measurement setup.

In the system overview, the status of each of the system hardware components is shown (

Figure 1

), clearly displaying any system component malfunction.

Historical data can be shown in powerful trends, where one or more parameters can automatically be displayed and compared to time, speed or process parameters (power, temperature, water level, etc.). Trends can also be updated live every second*.

* Depends on the measurement setup.

Machine information database

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. Based on this information and the actual shaft speeds, all defect frequencies are dynamically calculated and advanced diagnostic rules are applied.

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 example:

Defect frequency display

Each machine part and the interaction between parts are defined in the machine information database. Based on this information all machine defect frequencies are dynamically calculated and can be easily displayed in frequency spectra by the user.

In spectrum live mode, the defect frequencies are continuously updated based on the instant shaft speed.

Acceleration enveloping

Acceleration enveloping represents a major advancement in early detection of bearing faults which is superior to previous techniques for bearing fault detection.

Topology

Topology diagram is a powerful tool that illustrates frequency spectra vs. speed or time by using color separation enabling easy identification of variations in machine behavior. This can be used with any historical data or during run-up/coast- down.

2

3D plot

A 3D plot illustrates frequency spectra vs. speed, process data or time. The user can freely zoom, rotate or elevate the plot in order to view the diagram from any position.

The 3D plot can be used with any historical data or during run-up/coast-down.

Orbits

Using signals from two perpendicularly mounted transducers, the shaft orbital movement can be displayed and analyzed.

Orbits can be performed using the raw signal (true orbit), or using a filtered signal

(filtered orbit) at shaft speed or shaft speed harmonics as well as at a user defined frequency range.

3

Trend/bode

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 a user selected number of harmonics, as well as a user selected frequency range. Measurement data from different points can be overlaid in the same diagram for easy comparison.

Machine diagnostic

The powerful machine diagnostics includes standard rules for common faults such as unbalance, misalignment, various bearing faults, gear faults, cavitation, etc. User defined diagnosis rules can easily be designed. The machine diagnostics is always active, constantly monitoring incoming data, detecting machine faults and displaying clear text alarms.

Historical comparison of data

Frequency spectra taken at different times can be displayed and be individually compared. In addition, subtraction of a selectable measurement can be done. The selected reference data may be fixed and automatically matched with new or earlier measurements.

Harmonic analysis

For any given 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 machine component defect frequencies.

4

Sideband analysis

For any given frequency, sideband frequencies can be displayed making sideband effects much more visible. This is often used together with machine component defect frequencies.

Multi-parameter analysis Reports

The SKF @ptitude Observer provides a wealth of tools and features for sophisticated multi-parameter analysis. For example, the software supports oil quality monitoring displays, blade monitoring displays, and more.

Alarms and warnings

The SKF @ptitude Observer software has the capability to generate many different reports. All diagrams, plots and images can be used in various reports together with tabular data and notes. It is possible to pre-configure and store different types of reports like:

In SKF @ptitude Observer there are two types of alarms – primary alarms (checked typically every second*) and secondary alarms

(checked at every event and at a time interval selected by the user).

For acceleration enveloping and vibration measurement points, primary alarms perform at four different frequencies, fixed or speed dependent, with a selectable number of harmonics, and one frequency range. All measurement values can be exponentially averaged. Alarm levels can be configured to follow speed and/or load dynamically. Primary alarms can also be set to detect process measurement points for both high and low alarms with two levels each.

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.

All alarms are transferred to the SKF

@ptitude Observer Monitor and stored in the database together with corresponding measurement data. The SKF @ptitude

Observer Monitor computer can be equipped with relay cards containing 16 relays each, fully programmable to show any type of alarm. Additionally, alarm information can also be distributed via e-mail or SMS.

Last measurement report

Exception report

History report

Inspection report

Work notification report

Generated reports can also be stored in order to maintain a history of reports.

All reports can be sent to screen, PDF file, Word document, RTF,

Open Office or Printer and also posted to Internet, intranet or e-mailed.

Report templates allow quick and easy report configuration for use and reuse.

* Depends on the measurement setup.

Storage

Below is a description of the SKF @ptitude Observer system integrity:

The SKF @ptitude Observer software has the capability to store the evaluated data in a Microsoft SQL Server database. Using the royalty free Microsoft SQL Server Express, the database size can be up to four gigabytes. Using a full version of Microsoft SQL Server, the size is almost unlimited.

All stored data is marked with identification stating date and time for later use in troubleshooting and trend analysis.

Storage is made in the following form:

• checks all sensor signals and reports on failure a watchdog looks after both the SKF MultilogOn-line System IMx/

SKF MasCon units and the SKF @ptitude Observer Monitor and reports, then restarts upon failure easy for the operator to disable a sensor upon sensor failure system faults are stored in the database and can be accessed by the operator, for example, during system service

Trend storage

The trend data consists of different trend buffers storing data typically once every 10 seconds. Data is also stored in the archive buffer once every ten minutes. All trend buffers and the archive buffer are using

FIFO (first-in, first-out). Data is also stored in transient mode (see transient analysis).

Spectrum and Time Domain storage

At a user defined time interval, manually or upon an event (see below), vibration spectrum and time domain data is stored.

Spectrum and time domain data can be enabled for:

• vibration vibration, harmonic acceleration enveloping process FFT

Event related storage

The measurement points can be configured as members of event groups. An event can be an alarm or a change in process data.

When an event occurs, based on data from one of the group members, measurement data from all group members are stored.

Client/Server

SKF @ptitude Observer is a client/server application fully TCP/IP based, which means that SKF @ptitude Observer Monitor can be connected to Internet through a firewall and easily accessed from a Windows-based computer anywhere having SKF @ptitude

Observer installed.

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.

The Automatic database replication for SKF @ptitude Observer is a piece of software that is replicating the SKF @ptitude Observer database regularly between different database servers. The database servers can be located anywhere and connected by

Internet.

Profile for SKF @ptitude Observer

The Profile for SKF @ptitude Observer is a fully integrated plug-in module to the SKF @ptitude Observer software. It measures the profile of a rotor by using any type of vibration sensor and a tacho signal. The tacho signal normally monitors its signal from the same rotor but could also use signals from any shaft mechanically connected to the rotor to be monitored.

Transient module for SKF @ptitude Observer

The Transient module for SKF @ptitude Observer is a fully integrated plug-in module to the SKF @ptitude Observer software. It is a great help in analyzing a great variety of turbine related defects.

GPS for SKF @ptitude Observer

The SKF @ptitude Observer GPS is a plug-in for storage of the unit’s global position. This information is stored together with trend data to be used in various analysis situations e.g. trains, dump trucks, where the monitored object is moving and when it is of importance to know the position of the vehicle at the time of the measurement.

Advanced balancing for SKF @ptitude Observer

The Advanced balancing for SKF @ptitude Observer is a plug-in for on-line applications in order to make a full dynamic rotor balancing operation. The data input comes from SKF Multilog On-line System

IMx, SKF MasCon48, SKF MasCon16 and the balancing operation is done step-by-step. Dynamic rotor balancing can be performed from

1 up to 15 planes in one session and if needed the number of correction planes can be reduced using balancing plane elimination.

The data quality used by the balancing software is continuously checked and displayed to the operator. It is easy to go back and replace a bad measurement. The result from a balancing operation, including the Influence coefficient matrix, is stored in the SKF

@ptitude Observer database. If a rotor needs rebalancing, stored balancing data can be recalled in order to minimize the stops to only one.
