Aluminium Processing Plant
Vibration Monitoring System for Cold Rolling Mills and Tension Leveler
Correlating vibration data and machine data
by using one data acquisition system only
into an existing Condition Monitoring Program
Quality is certainly money in the Aluminium processing business. So, when a process was causing a critical vibration it was a major issue for one of the leading Aluminium process plant in the Middle East.
The iba system provides a state-of-the-art condition and vibration monitoring system. Since this system was installed many critical downtimes were avoided.
Process data cannot be excluded when doing a critical evaluation fo any process plant. In this case the data recording is performed by a ibaPDA System while the process analysis is performed on collected data with the ibaAnalyzer.
The vibration monitoring however is performed on distributed edge devices. After acquiring the vibration data from accelerometers, the ibaPDA add-on ibaInSpectra is used to analyze this data. The ibaInSpectra utilizes a frequency band analysis. Consequently machine, process and product data is used to eliminate quality problems related to vibration of the system.
"The ibaInSpectra Condition Monitoring solution allows Aluminum processing operators to easily monitor its entire production motors with gears and predict their maintenance needs."

ibaInSpectra - Real-time Condition Monitoring of process vibrations
With ibaInSpectra, vibrations are monitored continuously and possible error sources can be detected in an early stage. As ibaInSpectra is integrated in ibaPDA, not only can pure vibration analyses can be done, but possible relations between vibrational effects and process behavior can also be determined.
ibaAnalyzer-InSpectra can now be added to utilize the powerful ibaInSpectra library offline. Analysis configurations can first be designed and tested offline within ibaAnalyzer and transfer to ibaPDA for real-time vibration monitoring.
The devices of the ibaDAQ family allow a local data acquisition with the integrated ibaPDA system and an onboard data storage. You can access relevant data and information anywhere they are needed due to the exhaustive output options.
Key features of the used components
ibaDAQ is used as stand-alone unit to acquire and record data. ibaDAQ integrates a complete ibaPDA system and an internal solid-state disk (SSD) with sufficient memory space. The central unit is the heart of the iba modular system. It is connected with 4 Analog input modules. Which connect with accelerometers to collect vibration data directly from Gear boxes and motors. All channels are sampled synchronously with a rate of up to 40 kHz.
ibaInSpectra is used to continuously monitor any vibrations in real time in order to thus detect possible sources of error early on. As ibaInSpectra is integrated ibaPDA, not only mere vibration analyses are performed, but also possible relations between vibrational effects and process behaviour is immediately detected. By means of spectrum analysis, vibrations are monitored online and set into relation to other process parameters. When vibrations become critical to machine health or product quality, the plant operator is alarmed. In addition, a feedback in the plant control is implemented to automatically adjust the corresponding parameters.
ibaAnalyzer-InSpectra is the corresponding Add-on to ibaAnalyzer. Here it’s used to perform vibration analysis on collected data. With ibaAnalyzer-InSpectra it’s possible to search in existing collected data for anomalies and early signs of problems. It can be integrated in the vibration expert’s workflow the same way as conventional analysis software of handheld vibration measurement devices.
The advantage however is the fact that in combination with the ibaPDA-ibaDAQ system it’s easy to collect process and vibration data simultaneously and continuously or specifically triggered.
