5.4.1.6.1.2 Conventional condition monitoring
•
There exists a lot of measurement and process data that is not used for condition monitoring (CM). Links
and correlations with process parameters and further CM parameters can often be made possible only with
considerable expenditure.
•
CM systems are implemented as "isolated applications". In such cases condition monitoring is performed
by standalone sensor and measurement systems with standalone hardware and software
•
The range of different systems can lead to significant problems in the on-site operation of the system.
Different software solutions make it more difficult since there is separate hardware and a separate user
interface for each CM method and each CM tool.
•
In many cases, necessary expert knowledge specific to a system is not available. The complexity of some
configuration tools exceeds the user's existing expertise.
Using module X90CM480 together with B&R standard modules has the following advantages:
•
Easy exchange of process data and condition monitoring data
•
Easy integration of parameters in the overall process
•
Modular construction
5.4.1.6.1.3 Overview of condition monitoring methods
Method
Brief description of operation
Available signals/interfaces
Determination of the condition of coolants and lubri-
cants,
visual assessment, filtering, ferrography,
magnetic detection, spectroscopy,
radioactive trace analysis
Quantitative examination of wear products (filtering, magnetic
catches, ferrography, spectral oil analysis, particle counting) that
are obtained from the lubricant oil or coolant fluid
Regular taking of samples according to a defined time schedule
or according to operating hours
Quantitative comparison of the samples
Thermal diagnostics
Temperature sensors, thermometry,
infrared measurement technology
Recording of temperatures through sensors with different
physical modes of action
Recording of temperature distribution through detection of in-
frared radiation
Acoustic emission analysis
Airborne sound measurement, pulse analysis,
pulse density fluctuation analysis,
sound pressure measurement, sound emission lo-
cation
Airborne sound measurement from infrasound to ultrasound us-
ing a microphone
Multidimensional microphone structure for emission source lo-
cation
Recognition of microdamage (cracks), etc. through the mea-
surement of acoustic emissions of transient waves with high fre-
quencies
Vibration measurement
Structure-borne sound measurement,
FFT analyses, order analyses, modal analyses
Vibroacoustic diagnostics
Measurement of the structure-borne sound at bearing positions
or structures with accelerometers, analysis and evaluation
Using suitable measurement systems,
these condition monitoring methods can be
processed in the B&R system using ana-
log/digital inputs or bus controller modules.
Electrical parameters, motor current analysis,
Isolation resistance measurement
Compilation of electro-technical parameters and analysis with
regard to condition monitoring
These condition monitoring methods can
be processed in the B&R system using
analog/digital inputs, bus controller mod-
ules or B&R drive systems (different func-
tions from system to system).
