When looking for the best way to measure run-out/vibration, there are a number of important factors to consider, the type of run-out or vibration (direction), the type of measurement system, and the installation environment. Selecting equipment that doesn't adequately meet your needs can lead to insufficient precision and increased man-hours during production. This site is designed to help those looking for a run-out/vibration measurement system discover the best way to do so with confidence.
A laser beam that has been expanded into a line is diffusely reflected from the surface of the target. This reflected profile is formed on the HSE3-CMOS and by detecting changes in the position and shape of the reflection, it is possible to measure targets run-out.
KEY POINTS
When measuring with a 1D laser displacement sensor, the peak cannot be captured at all times if the peak point shifts to the left or right. The peak point can be tracked at all times by using a 2D laser displacement sensor.
Measurement must be performed at a sampling rate of at least ten times the oscillation frequency.
