CoDis – Vibration Monitoring

Features

Overview

The CoDis system provides early warning, real time protection and information for predictive maintenance of motors and generators including:

• Alarming System
• Electrical Transient Recorder and Power Quality Monitoring
• Integrative software module for diagnostic monitoring (CoDiS DM). Each of the modules can be installed as an individual system

Data Acquisition

CoDiS continuous online monitor is designed for recommended measurement layout with 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)
