Emerson EPRO MMS6220 Turbomachinery Eccentricity Card

Emerson EPRO MMS6220 Turbomachinery Eccentricity CardProduct Overview The Emerson EPRO MMS6220 functions as a specialized dual channel monitor within the MMS6000 machinery protection system, specifically engineered for Eccentricity and Shaft Vibration measurements. It captures critical radial displacement data from non contact eddy current probes (PR6422 PR6423 series). This module plays a vital role during turbine startup and coast down phases by detecting shaft bowing or thermal warping before the

Propagation Delay: 20 ms (Off to On and On to Off)
