Product Overview
Emerson A6220 is a dual-channel shaft-eccentricity monitor for AMS 6500 machinery protection systems.
The monitor measures low-speed shaft bow or eccentric movement with supported eddy-current probes and CON converters, comparing configured values with alert and danger setpoints. Emerson documents peak-to-peak, minimum/maximum and continuous-gap measurement modes.
Key Functions
Low-Speed Eccentricity Monitoring
Measures shaft movement associated with bow or eccentricity during slow roll and other applicable low-speed conditions.
Configurable Measurement Modes
Supports hot-configurable peak-to-peak, minimum/maximum and continuous-gap measurements for each channel.
Machinery Protection Outputs
Provides buffered and proportional outputs while evaluating channel health and configured alarm limits.
