Product Positioning and Functions
The Emerson A6312 is a dual-channel speed and phase monitor, specifically designed for industrial rotating machinery (such as steam turbines, gas turbines, compressors, hydro turbine machinery, etc.), and belongs to high-reliability monitoring equipment. Its core functions include:
Speed Monitoring: Real-time measurement of the rotational speed of the shaft, supporting zero-speed alarm, reverse rotation monitoring, and process condition tracking.
Phase/Phase Angle Monitoring: Capturing the phase pulse signal for each rotation using displacement sensors, used to analyze changes in mechanical health status (such as vibration, eccentricity, etc.).
Redundant Mode: Supports automatic switching of the main/backup speed meters, ensuring continuous system operation and maintaining phase continuity during fault switching.
API 670 Standard Compatibility: Combined with the AMS 6500 monitor, forming a complete mechanical protection system to meet industry safety standards.
