The diagnosis of bearing damage in roller bearings is an integral part of servicing and maintenance tasks. Increasingly, technicians rely on condition monitoring systems (CMS) for machine diagnoses in plants and factories. Many CMS systems are based on vibration measurements. Two contrasting approaches exist: the diagnostic, qualitative approach (producing an envelope spectrum); and the quantitative approach (measuring vibration velocity).
Delphin Expert Vibro Devices are suitable for both approaches. As a Delphin distributor in North America, CAS DataLoggers supplies these systems for vibration monitoring applications in every industry.
The quantitative approach integrates the acceleration time signal into vibration velocity. This vibration velocity is then usually monitored as a sum level. An Expert Vibro device is able to calculate an envelope spectrum from the time signals of acceleration sensors. With this data, users get detailed information on the condition of the bearing (inner and outer rings, cage and ball bearings).
Application Features:
• Evaluation of vibration velocity Veff according to DIN ISO 10816
• FFT analysis within the device / frequency band monitoring
• Evaluation using envelope spectrum on bearing damage
• Monitoring of vibration levels
• Intelligent recording within the device
• Visualization and analysis using time signal, trend spectrum, FFT cascade, orbit and polar diagrams
Flexible Vibration Measurement:
Vibration measurement is made easy with the Expert Vibro, a data acquisition device for acquiring transient signals and vibrations. The latest FPGA-based processor technology enables 16 synchronous channels to be processed at high sampling rates. Meanwhile the system’s 24-Bit A/D converters ensure high precision. Users can switch between voltage measurement, IEPE or shaft vibration sensors.
Users are able to enact flexible triggering via integrated comparators and digital inputs. Measurement data is spontaneously monitored with digital outputs being switched within msecs in the event of limit value violations.
Typical Areas of Application:
• Bearing damage diagnoses
• Envelope spectrums
• Analysis of vibrations in drives
• Analysis of gearing problems
• CMS on roller bearings
