Vibration and Eccentricity Measurement Selection Guide

This document provides a selection guide and measurement principles for vibration and eccentricity measurement using reflective sensors, thrubeam sensors, and spectral-interference methods. It covers successful applications such as detecting vibration in ultrasonic welders, measuring runout in motor shafts and HDDs, and includes technical details on triangulation, spectral-interference, and 1D thru-beam measurement principles.
