CoDis PMU – Portable Vibration Monitoring Unit

Features

Data Acquisition

CoDiS PMU is designed for measurement of 16 analog input channels that can be configured for:

• Trigger Signal
• Relative Shaft Vibration Signals
• Absolute Bearing Bracket Vibration Signals
• Axial Displacement Signals
• Electrical and Process Parameters

Data Analysis

The CoDis diagnostic software is capable of the following:

• Configurable channel sensitivity and offset to adjust for different sensors
• History trend analysis
• Analysis of waveform (raw) data acquired on-line or off-line from an ASCII file
• Spectra calculation (FFT and Waterfall)
• Ability to store condition vector data (the most relevant parameters calculated from waveforms) to ASCII file
• Orbit analysis with compensation for different sensor position in different measurement planes
• Data plotting including Bode plot, Nyquist plot and Shaft centerline plot
• Slow-roll module enabling data analysis down to very low rotational speeds (below 5 rpm)
• Analysis of any data over shared network through TCP/IP

Options

Optional modules for the portable CoDis vibration monitoring unit includes:

• Air-gap and magnetic field analysis  is available to provide analysis of pole profile, stator and rotor shape and shorted turns on rotor poles
• 3D Run Out module
•  Critical speed/ bearing stiffness module
• Connection of process quantities
• Statistical analysis of recorded data (histograms)
