EMERSON A6220 expansion monitoring module
Product Overview
The EMERSON A6220 Differential Expansion Monitor Module is a differential expansion monitoring module within the Emerson AMS 6500 Mechanical Health Monitoring System. It is specifically designed to monitor the axial thermal expansion difference between the rotor and casing of steam turbines, gas turbines, and other large rotating machinery. By measuring differential expansion parameters in real time, the A6220 helps operators promptly identify mechanical problems caused by thermal deformation, installation misalignment, or operational anomalies, thereby ensuring the safe and stable operation of the equipment.
This module employs high-precision displacement measurement technology and can be used in conjunction with displacement probes such as eddy current sensors. It integrates alarm and protection functions, providing reliable online monitoring and predictive maintenance support for critical equipment. As an important component of the AMS 6500 series, the A6220 is widely used in power generation, oil and gas, petrochemical, and heavy industry sectors.
