overview：
Emerson A6410 Valve and Case Expansion Monitor is a specialized monitoring module designed for integration with the AMS 6500 Machinery Health Monitor. It is specifically tailored for monitoring valve position and case expansion in critical rotating machinery, such as steam turbines, gas turbines, compressors, and hydro turbines. Below is a detailed overview of its features, functionality, and applications:
Fuctions & Features:
-
Valve position monitoring: The Emerson A6410 can measure the main steam inlet valve stem position and display it as a percentage of opening, providing the operator with an indication of the current load on the turbine.
-
Casing expansion monitoring: The Emerson A6410 usually uses two inductive displacement sensors installed axially, parallel to the shaft and located on both sides of the turbine casing for casing expansion monitoring. During startup, the expansion rate on both sides of the turbine casing is monitored to prevent casing bending and causing the rotor to collide with the casing.
-
Channel functions are diverse: Channel 1 of the Emerson A6410 can measure static values such as casing expansion, as well as dynamic quantities such as displacement, angle, force, torque, etc.; Channel 2 is used for static measurements and relative displacement (relative to channel 1) measurements.
