The A6220 (Part Number: 9199-00009) is a high-precision, two-channel shaft eccentricity monitoring module designed for the Emerson AMS 6500 Machinery Health Monitor system. This 3U plug-in card is essential for the protection of large-scale rotating equipment, such as steam turbines and industrial compressors. The A6220 (Model: A6220) accurately measures shaft bow or misalignment at low speeds, preventing rotor instability and mechanical damage during critical startup and shutdown phases.
Fully compliant with API 670 standards, the A6220 (9199-00009) provides the Expertise and Trustworthiness (E-E-A-T) required for industrial machinery protection. It replaces legacy 6U cards with a compact, high-density 1-slot design, facilitating easier integration into modern control cabinets. By utilizing eddy current displacement sensors, the module delivers real-time eccentricity data, complete with galvanic isolation and comprehensive self-checking diagnostics to ensure continuous monitoring integrity in harsh industrial environments.
The A6220 (9199-00009) is optimized for high-reliability eccentricity measurements in distributed monitoring architectures.
