CardVibro Air2 (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.

■ 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 scratches 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.
