2 Introducon
ibaInSpectra is used to connuously monitor any vibraons in real me in order to detect pos-
sible sources of error at an early stage. As ibaInSpectra is integrated in ibaPDA, not only mere
vibraon analyses can be performed, but also possible relaons between vibraon eects and
process behavior can be detected immediately.
Using spectral analyses, vibraons can be monitored online and correlated with other process
parameters. If vibraons reach crical states, the plant operator is informed immediately, for
example by alarm message or e-mail. In addion, a feedback in the plant control can be imple-
mented to auto macally adjust the corresponding parameters.
2.1 ibaInSpectra – the concept
Designed as an integrated technology module of ibaPDA, ibaInSpectra serves to monitor and
analyze vibraons. ibaInSpectra provides dierent modules, which are congured in the I/O
manager of ibaPDA.
■ The expert module oers the most diverse parameterizaon opons for the frequency band
analysis and is the preferred tool for vibraon experts. The frequency bands to be monitored
can be dened as xed or dependent on process variables and checked for limit value ex-
ceedance.
■ The auto-adapng module automacally learns spectra for dierent process condions and
uses this as a reference to detect changes in the spectrum over me.
■ The orbit module is used to monitor and analyze the sha moon, for example of journal
bearings.
■ The universal module is easy to congure and calculates the most common characterisc
values for vibraon monitoring in the me domain.
■ The fan module is used to monitor fans and calculates special indicators for the state of fans.
ibaAnalyzer-InSpectra makes it possible to congure calculaon rules in the form of pro-
les o ine and to test them on already recorded data. These proles can be transferred to
ibaInSpectra with the help of export and import funcons and used there. Exisng calculaon
proles from ibaInSpectra can also be transferred to ibaAnalyzer-InSpectra in order to adjust
the calculaons or limits.
With ibaAnalyzer-InSpectra not only raw signals and calculated characterisc values, but also
the calculaon proles can be opened in ibaAnalyzer. Therefore it is also possible to carry out
the calculaons of ibaInSpectra oine. Characterisc values that have triggered an alarm can
be validated and the problem can be analyzed oine. The extensive features of ibaAnalyzer-In-
Spectra oer a useful opon here: Changing the analysis rules gives you a beer view of the
informaon relevant to the respecve problem. Due to the integraon in ibaAnalyzer, it is very
easily possible to use and compare all recorded process parameters for the analysis.
The focus when acquiring mechanical vibraons is usually on acceleraon sensors or distance
sensors for ibaInSpectra orbit. Dierent input modules from the iba hardware are available for
connecng these sensors.
