If you were interested in measuring a very high gearmesh frequency, which units of measure would be your best choice?

When measuring high gearmesh frequencies, acceleration is typically the most effective choice among the available options. At these frequencies, the vibration characteristics can change rapidly, and acceleration measurement captures these quickly varying signals more accurately than the other measurements.

Acceleration provides insights into the dynamics of the vibrations and is particularly useful for identifying potential issues such as gear misalignment or wear. As the gearmesh frequency increases, the amplitude of acceleration can be more pronounced, making it easier to detect anomalies in the operation of machinery.

While displacement measures the actual movement of components, it may not be sensitive enough at very high frequencies, and velocity can smooth out some of the critical details related to rapid changes in vibration. Frequency, on the other hand, indicates how often something occurs but does not provide information about the severity or nature of the vibration itself, making it less suitable for diagnostic purposes related to high gearmesh frequencies.
