Condition monitoring
Condition monitoring (colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance. The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences. Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure. Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery like belt-driven equipment, (compressors, pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing (NDT) techniques and fit for service (FFS) evaluation are used for static plant equipment such as steam boilers, piping and heat exchangers.
Condition monitoring technology
The following list includes the main condition monitoring techniques applied in the industrial and transportation sectors:
- Condition monitoring overview
- Vibration analysis and diagnostics
- Lubricant analysis
- Acoustic emission
- Infrared thermography
- Ultrasound
- Oil condition sensors
- Motor condition monitoring and motor current signature analysis (MCSA)
- Model-based voltage and current systems (MBVI systems)
Most CM technologies are being standardized by ISO and ASTM.
