Open and
Versatile
In contrast
to many other Condition Monitoring systems, ibaInSpectra is not a
manufacturer-specific system or limited to individual machines, but uses the
broad connectivity of ibaPDA and the iba hardware. Thus, it is perfectly made
for the use in heterogeneous automation structures, that are characterized by a
great number of different technical disciplines and controller types.
Due
to the smooth integration in ibaPDA, vibrational measurement data as well as
other machine, process, material and quality data can be acquired centrally and
put into relation to each other. Hence, besides the pure vibration analysis of
a single machine, also possible effects of the vibrations on the process stability
and product quality can be detected.
Real-time
Analysis
Many
systems for Condition Monitoring are designed for long-term trends and often
analyze the vibration sensors in intervals of hours or days for a short time.
However, with ibaInSpectra, the sensors can be monitored time-synchronously and
continuously and the current frequency analyses can be displayed in real-time.
Negative
trends as well as significant correlations can be detected early in the
process. Critical conditions or exceeded limit values can be signaled
immediately, which contributes significantly to the protection of man, machine
and material. Moreover, process parameters that influence the vibrational
behavior, can be adapted automatically online.
Flexible Configuration
Designed as integrated technology module of ibaPDA, ibaInSpectra serves as
software for band parameter analysis preferably for mechanic vibrations.
ibaInSpectra offers different modules that are configured in the I/O Manager of
ibaPDA.
·
The expert module offers the most diverse opportunities
for parameterizing the frequency band analysis and is the favored tool for
experts in the field of vibrations.
·
The standard module can be configured in an easy way and
calculates the most common characteristic values for vibration monitoring in
the time domain.
·
The fan module is made for monitoring fans and calculates
especially indicators for the status of fans.
More modules are in preparation.
In the expert module, the frequency bands that are to be monitored can be
defined freely, statically as well as dynamically depending on other
measurement values.
The following parameters are determined as result of the analysis for
every frequency band:
·
Peak
·
RMS (root mean square)
·
Peak frequency
For RMS and peak, two limit values (alert, alarm) can be additionally
defined. Besides the values from the frequency domain, further values like
minimum, maximum, average value, RMS or Crest factor are determined in the time
domain of the signal.
The calculation bases for the analysis can be adapted individually by the
user on many levels and stored as profiles.
Besides the sensor type and the spectrum type, FFT calculation parameters
like the number of samples, window type and overlap percentage can be set.
There are different methods for determining the average value as well as
the possibility of detrending for compensating a slow drift of the measured
value.
Profiles that have been defined once, can be stored and then used several
times.
Alert and Alarm
When
configuring the alert and alarm limit values, the ibaInSpectra expert module
automatically supplies digital signals which are activated as soon as the limit
values are exceeded.
Via
the output interfaces of ibaPDA, these signals can be made available to other
systems for alerting or interventions in the process control.
Operation and
Visualization
ibaInSpectra
expert modules have an own branch in the ibaPDA signal tree. For the display,
only an FFT view needs to be opened and the ibaInSpectra module has to be
dragged in by means of Drag & Drop. The standard views waterfall, frequency
band, current value tables and time domaine trend of the input signal are
available immediately. They can be displayed and hidden when required.
By
means of markers that can be freely defined, any desired frequency and its Harmonics
can be followed in the display (order tracking). This can be really of interest
in case of dynamic operating states of a plant.
Consistency up
to the Offline Analysis
When
recording with ibaPDA, the ibaInSpectra expert modules are stored completely
with all the calculated characteristic values in the measured data file. In
ibaAnalyzer, all modules are available in the signal tree and the determined
band parameters can be dragged via Drag & Drop into the trend view or used
for other calculations.
