Emerson Epro A6125 Piezoelectric Vibration Monitor

Overview

The Emerson Epro A6125 is a high-reliability dual-channel vibration monitor. It continuously monitors casing vibration in critical rotating machinery. Designed for turbines, compressors, and pumps, it supports predictive maintenance and prevents unplanned downtime. The module complies with API 670 standards and integrates seamlessly with the CSI 6500 machinery protection system. It works with piezoelectric accelerometers and velocity sensors for precise vibration measurement.
