The Emerson A6125 is a dual-channel thrust position monitoring module designed for the AMS 6500 Machinery Health Monitoring System. It measures axial (thrust) displacement of rotating machinery shafts using eddy-current proximity probes, providing critical data for turbine, compressor, pump, and motor protection.
The A6125 ensures continuous monitoring of shaft axial position, enabling protection against thrust bearing wear, misalignment, and mechanical failure. Its compact plug-in design and industrial-grade construction make it suitable for harsh operating environments.
