    1. Overview
    The A6220 is a high‑precision dual‑channel eccentricity and slow‑roll vibration module for Emerson AMS 6500 and MMS 6000 systems. It monitors shaft bow/thermal distortion during turbine startup, turning gear, and warm‑up phases, filtering high‑frequency noise to focus on low‑speed rotational dynamics. Critical for large steam/gas turbine protection.
