Vibration measuring systems

CardVibro Air2 Series (VM-2012/VM-2012C)

The first portable vibrometer communicating by WiFi
Precise measurements are now possible even in environments that gave difficulty on vibration measurements, by high speed communication powerful data processing.
The application (Air2 Light) demanded much has been released making it easier to use.

  • For vibration condition check

  • For measurement of small displacement
    Check the movie on You Tube

  • For violently vibrating place

  • For high place

  • For narrow place

  • For partitioned area


  • ■ Simultaneous measurement 


    Air2 Light

    There are many functions to express characteristics of vibration in general, so conventional vibrometers usually needed to switch the mode every time to measure by each factor. However, on pressing a button, you can measure acceleration, velocity and displacement simultaneously when you use CardVibro Air2 function for simultaneous measurement. It can save operating time and prevent miss-measurements.

  • ■ Evaluation function 


    Air2 Light

    CardVibro Air2 can quickly evaluate the condition of the rotational machinery such as blowers or motors at the site with its customized standard. CardVibro Air2 enables everybody to make same judgements on same machinery conditions, having the judgement functions regarding standard as the Vibration Severity ISO-10816 (JIS-B-0906) and original bearing evaluation means.

  • ■ USB cable connection 


    Air2 Light

    Even if wireless connection is not available, measurements by USB cable connection to tablet PC are available.

  • ■ FFT analysis 


    When the measured vibration level is too large, FFT analysis is available to investigate. CardVibro Air2 has a high resolution analysis function of 12800 lines. Comparison of bearing vibration is possible on frequency components.

  • ■ Data saving 


    All acquired data can be saved. Using the data management software*, highly efficient management is possible on the transferred data from PC.(*option)

  • ■ Waveform observation 


    Beat phenomena or scrathes on bearings give some features on the vibration waveforms. It allows easy recognition of faults by waveform or graph observation. Maximum 30 minute* waveform can be recorded.
    *Depends on a condition

  • ■ Continuous monitoring function 


    Waveforms or FFT results are monitored almost in real time.

  • ■ Route setting function 


    If the measurement point and order are specified in advance, the data will be displayed in the order. Data management is possible by machine name, measurement point, or registration number.
    * Data management software (option) is needed.

  • ■ Trend graph function 


    The trend graph which needed conventionally data management software now can be displayed solely by Air2 Light without using such software. Furthermore, such data can be saved by CSV to be attached to e-mail.
