Rion VA-12 Vibration Analyser

Click here for The VA12 introduction movie

The VA-12 is a powerful (yet easy to use), practical and self-standing machinery vibration analyser which stores data in standard formats (csv and standard wav files) enabling analysis without the user being tied to a specific condition monitoring package or particular analysis software. However, you don’t have to download the instrument before you can analyse the data. The full colour backlit screen is visible in all lighting conditions and the user can see the characteristics of the vibration data and measurement parameters properly whilst on site.

The meter performs four principal functions. As a vibration meter it will simultaneously display overall levels of vibration in terms of acceleration, velocity and displacement. As an FFT analyser it will show the (instantaneous, linear or exponentially averaged or maximum) spectrum in terms of acceleration, velocity or displacement. The waveform for each vibration parameter can be viewed when the meter is put in Time mode. Finally, the instrument can also store calibrated wav files to the SD card allowing full post processing on any measured signals using whatever post processing software you have available (as long as it can read a standard wav file).

  • Exceptional colour full information display – results, traces and instrument settings clearly visible in all lighting conditions
  • Very easy to use with an intuitive and logically consistent user interface
  • Up to 12 hours operation on AA batteries
  • Practical yet accurate PV-57I accelerometer supplied with practical coiled cable (extensions available)
  • Can be used with most CCLD accelerometers
  • Magnetic attachment supplied (sensor can also be attached with M6 studs)
  • Frequency range (with supplied accelerometer) 1 Hz – 5 kHz for acceleration (3 Hz – 3 kHz for velocity and 3 Hz – 500 Hz for displacement)
  • 0.02 – 141 ms-2 rms acceleration (with supplied accelerometer)
  • 0.2 – 141 ms-1 rms velocity (with supplied accelerometer)
  • 0.02 – 40mm mm p - p displacement (with supplied accelerometer)
  • Displays overall rms acceleration (with peak and crest factor) simultaneously with rms velocity and p – p displacement simultaneously in vibration meter mode
  • FFT analysis (of acceleration, displacement or velocity)
  • Up to 3200 lines
  • Frequency Ranges 100, 200, 500, 1000, 2000, 5000, 10 000 & 20 000 Hz
  • Zoomable frequency axis (x 2, 4, 8, 16)
  • Zoomable magnitude axis (up to x 1024) in FFT mode

  • Can record calibrated wav files (duration dependent on bandwidth - up to 10 seconds @ 20 kHz bandwidth or 2000 seconds @ 100 Hz bandwidth) during FFT measurements
  • Data stored to SD card (available either via card reader or via the instrument’s USB port – the SD card is then seen as a virtual disk)
  • Flexible internal and external trigger options
  • Memory for 100 files each containing 1000 measurements
  • Display can be stored as a colour bitmap at any time
  • Supplied with a practical protective cover
