AVL 3000/AQ

Analyser of rolling bearing vibrations.

The analyser AVL 3000/AQ is a laboratory measuring device with programme equipment which servers for the identification of rolling bearing defects in a non-destructive way using the frequency analysis of a signal obtained from the mąeasuring device for the rolling bearing vibration level IL 100R/2000.

Datasheet

Tech­n­ical data

Meas­ur­ing the level of vibra­tion speed

  • frequency range: 50 Hz - 10 kHz
  • measuring time: optional from 100 ms to 180 s
  • evaluated parameter: vibration level (RMS), maximum vibration amplitude, PEAK CREST FAKTOR

Spec­tral analysis

  • frequency and-amplitude spectrum: from 50 Hz to 10 kHz
  • evaluated parameter: vibration level (RMS) in three ranges: I. 60 Hz - 300 Hz, II. 300 Hz - 1800 Hz, III. 1800 Hz - 10,000 Hz
  • maximum amplitude in the third vibration range
  • PEAK CREST FAKTOR

Defects analysis

  • frequency range: 1.8 kHz to 10 kHz
  • evaluated parameter: vibration level (RMS), maximum vibration amplitude, PEAK CREST FAKTOR
  • frequency and amplitude spectrum of the envelope: from 10 Hz to 500 Hz
  • defect identification: determination of repeat frequency defects 0 ms to 100 ms

Time-related char­ac­terist­ics of vibra­tion level

  • record of vibration level (RMS) in all ranges
  • performance time: 5, 10, 20 min

Oscilo­scope

  • monitoring of input signal
  • frequency range: 50 Hz to 10 kHz

Cal­cu­la­tion of char­ac­teristic frequencies

  • the frequencies are calculated from the kinematic diagram of a rolling bearing
  • the results are archived
