VAST - CM 21


Vibrometer CM-21 is an ideal tool for the machine operator or mechanic. It is pocket size device that combines reliability easy-use and wide range of functions.

It is used to measure high and low frequency vibration, bearing condition, temperature, rotation speed as well as for audio monitoring of vibration signals. The main application is condition monitoring and bearing condition assessment.

Following are some of the important features of the DC-23 analyzer.

  • The CM-21 is used to measure RMS, Peak, Peak-Peak, Peak-factor of:
    • Acceleration
    • Velocity
    • Displacement
  • Additional functions include
    • Rotation speed measurements
    • Temperature measurements
    • Audio monitoring of the vibration signal
  • Alarm levels can be set for each vibration measurement. It allows detection of the alarm state of equipment during measurements.


  • The VibroLevel software is supplied with the CM-21. It allows
    • Configuration of database and save the history of measurements for trending and analysis
    • Setup route maps for measurements, load and unload them to the CM-21
    • Setting alarm alarm levels individually for each point
    • Reports are exported in the MS Excel files.
