Description
EMERSON MMS6312 is a dual-channel rotational speed monitor from EPRO’s MMS6000 series, designed for precise shaft speed measurement in rotating machinery.
Product Overview
The MMS6312 processes signals from pulse sensors and triggering wheels to monitor rotational speed, standstill, and key-phases.
It supports independent or combined channel operation for direction detection and speed differential monitoring.
