Turbomachinery Vibration Solution : ORBIGATE

ORBIGate is the dedicated software module for industrial rotating machinery vibration during diagnostics as well as acceptance works. Easy to use, it provides all the tools to bring the highest level of set-up simplicity and efficiency to the user.

Featuring simultaneous portable acquisition on up to 32 dynamic channels, an entire machine train can be tested during transients or steady states. The system acquires and analyzes orbit, Bode, shaft and casing vibration. Typical graphics are orbits, shaft centerline, spectra, Bode and polar diagrams, trends, waterfall, overall peak to peak, 1X (amplitude and phase). In a typical situation the OROS instrument is connected to the outputs of the monitoring system as shown in above figure.

For analyzing rotating machinery vibration, ORBIGate features, among others, the following graphics and displays:

• Tabular list: Gap voltage, Overall, orders amplitude and phase (0.5X, 1X, nX), Sub1X, SMax
• Orbits (Overall and nX fi ltered)
• Full Shaft Motion: shaft centerline + clearance circle + orbits
• Bode, polar and trend plots
• Full and Half Spectrum, cascade and waterfall
• Gap voltage reference
• Slow roll vector reference for run-out correction
• Real-time acquisition, post analysis (based on raw signal recording) and data navigation
• Multichannel alarm conditions and actions
• Journal bearing tools: Gap voltage reference, Run out compensation
• Record & playback: comfort, flexibility  security
• Export & Reporting

Efficiency is the key word in the field. For that reason set-up in ORBIGate has been dedicated to all turbomachinery users: no need to be an expert! ORBIGate is the fruit of OROS collaboration with experienced field users: it is designed by users for users. The sequencing of the configuration has been developed to be fully natural for such measurements.

A complete and simple interface is provided to set-up and display the graphics required for the application.
Several type of graphics can be mixed freely in the same layout. The master navigation cursor allows the user to navigate through the pile of recorded data. When doing that, all cursors are synchronized in order to display the data at the chosen instant (RPM, absolute date or relative date).
