Emerson CON011/914-100 | API 670 Machinery Monitoring Module

EPRO CON011/914-100 Eddy-Current Signal Converter – Product Description

Overview

The Emerson EPRO CON011/914-100 is a hardened eddy-current signal converter engineered for demanding rotating-machinery environments. It delivers accurate, stable signal conditioning for proximity probes used in vibration monitoring and shaft-position measurement. Moreover, the converter integrates seamlessly with the PR6422–PR6426 probe families, allowing technicians to maintain consistent performance across mixed machine assets. The robust design supports API 670 compliant protection systems, and it performs reliably in high-temperature and high-noise environments common to turbine and compressor applications.
