Epro MMS3110/011-000 Dual-Channel Vibration Transmitter

Product Overview

The MMS3110/011-000 is a dual-channel shaft vibration transmitter from Epro (Emerson MMS 3000 series), developed for continuous condition monitoring and protection of rotating machinery. It processes signals from eddy current proximity probes and converts them into standardized analog outputs for control and protection systems.

It is engineered for turbomachinery environments where stable vibration measurement, fast fault detection, and high system availability are required.

System Design

The unit integrates two fully independent measurement channels within a single housing. Each channel performs separate signal conditioning, linearization, and diagnostic evaluation, enabling parallel monitoring of two vibration points such as bearing positions or shaft axes.

The architecture reduces external instrumentation requirements while improving system reliability and response time.

Redundant 24 V DC power inputs provide continuous operation even in the event of a single power supply failure.
