Description
The EPRO MMS6220 (Type 9100-00009) is a high-precision, dual-channel monitoring module specifically engineered for the protection and analysis of rotating machinery. Within the MMS6000 series, this unit serves as a critical diagnostic tool by measuring shaft eccentricity—the deviation of a rotating shaft’s geometric center from its center of rotation. This measurement is essential for identifying potential mechanical imbalances, thermal bowing, or bearing issues in large industrial equipment, such as steam turbines, gas turbines, hydro turbines, and compressors.
