Description

The Emerson PR9268/017-100 is a mechanical electrodynamic velocity sensor designed for absolute vibration measurement of critical turbomachinery applications. It provides case vibration monitoring for systems such as steam, gas, and hydro turbines, as well as compressors, pumps, and fans. Operating as a self-powered device, this velocity sensor converts mechanical vibration into an electrical signal proportional to velocity, transmitting dynamic data to continuous machinery protection systems like AMS monitoring platforms.

Features

  • Mechanical velocity sensor design optimized for critical turbomachinery protection.
  • Self-powered design requiring no external excitation power for signal generation.
  • Robust housing constructed from stainless steel for harsh industrial environments.
  • Omni-directional sensor orientation capability enabling versatile mounting configurations.

Applications

  • Steam, gas, and hydro turbine case vibration monitoring.
  • Turbo-compressor vibration measurement.
  • High-performance industrial pumps and ventilation fans.
  • Power plant and petrochemical industrial rotating machinery protection.
