Product Overview
The Epro MMS6210 is a high-precision dual-channel shaft displacement monitoring module designed for continuous machinery condition monitoring. As part of the Epro MMS6000 series, the MMS6210 is primarily used to measure and monitor shaft displacement in rotating equipment such as turbines, compressors, motors, and pumps.
This module operates by processing signals from non-contact eddy current proximity sensors and converts them into meaningful shaft displacement values. Its dual-channel capability enables simultaneous monitoring of two independent measuring points, offering greater flexibility and reduced rack space requirements.
Engineered for industrial reliability and diagnostic accuracy, the MMS6210 is equipped with alarm relays, LED status indicators, and configurable thresholds, making it a critical component for predictive maintenance systems and machinery protection schemes in high-demand industrial environments.
