Description

Product Description

Overview
The MMS3120/022-000 is a high-performance dual-channel vibration monitoring module from Epro, part of the Emerson MMS3000 series. Designed for continuous condition monitoring of rotating machinery, it delivers precise and reliable bearing vibration measurements using both electrodynamic and piezoelectric sensing technologies. This module is ideal for applications requiring accurate vibration trending and alarm functions in protection and predictive maintenance systems.

Measurement Capabilities
The transmitter captures signals from two independent vibration channels, allowing simultaneous monitoring of separate bearing locations. It supports multiple vibration metrics, including velocity, acceleration, and peak displacement. Advanced digital signal processing ensures stable and accurate readings even under fluctuating operational conditions.
