CM21

Vibration and technological parameters are the most frequenntly measured magnitudes for the condition monitoring applications. Multifunctional vibrometer CM-21 allows all these measurements.

CM-21 is used for periodic monitoring of vibration according to ISD 10816 in all standard frequency bands. Additionally it allows measurements of additional parameters for monitoring friction units condition in rotating machines. These are high frequency vibration levels, temperature, peak factor.
