System Integration and Applications
As the core rack of the AMS 6500 ATG system, the A6500-SR must work in conjunction with other modules in the system to achieve complete machinery protection and predictive functions:Module Collaboration: The installed A6500-UM Universal Measurement Cards can collect key parameters such as shaft vibration, shaft eccentricity and rotational speed. The data is transmitted to the A6500-CC Communication Cards via the internal RS 485 bus, which then convert the data into Modbus RTU, Modbus TCP/IP or OPC UA protocols and transmit it to upper computers or analysis systems (e.g., the ATG View mobile application), enabling remote data viewing and parameter configuration.
Application Scenarios: Widely used in the petroleum, chemical, power, machinery manufacturing and other industries, it provides real-time condition monitoring, fault early warning and safety protection for rotating machinery such as steam turbines, gas turbines, compressors and water turbines. It helps factories implement asset health management and predictive maintenance, and reduce unplanned downtime.
