The Emerson A6140 is a dual-channel eccentricity and phase reference monitoring module for the AMS 6500 Machinery Health Monitoring System. It continuously monitors shaft eccentricity (runout) and provides a stable phase reference signal for synchronous vibration analysis.
By interfacing with eddy-current proximity probes, the A6140 detects mechanical issues such as bent shafts, misalignment, or rubs, ensuring early fault detection and reliable turbine, compressor, pump, and motor protection. Its compact plug-in design and industrial-grade construction make it ideal for harsh operating environments.
