Product Overview

The Emerson PR9268/302-000 is a precision-engineered electrodynamic velocity sensor designed for the continuous monitoring of absolute mechanical vibrations in industrial machinery. Primarily utilized within the Epro product family, this sensor converts mechanical motion into an electrical voltage signal proportional to the vibration velocity. Unlike standard proximity probes, the PR9268/302-000 operates on an electrodynamic principle, making it exceptionally reliable for detecting low-to-medium frequency oscillations in rotating equipment. Despite its official discontinuation by the manufacturer in late 2018, it remains a critical component for maintaining legacy DCS and vibration monitoring frameworks.
