Description

Brief Product Description

The Emerson PR9268/017-100 is a rugged electrodynamic velocity sensor engineered for measuring absolute vibration in large rotating machinery. It provides highly accurate data for predictive maintenance in extreme industrial environments, supporting critical assets like turbines, pumps, and fans.

​Product Description

Precision Absolute Vibration Monitoring

The Emerson PR9268/017-100 operates as a high-precision electrodynamic velocity sensor, specifically designed to capture absolute machine vibration. Unlike standard accelerometers, this EPRO series transducer utilizes a suspended coil moving within a permanent magnetic field to generate a voltage proportional to the vibration velocity. This mechanical measurement principle ensures high sensitivity and stability, particularly when monitoring large-scale rotating equipment in the power generation and petrochemical sectors. By providing clean, real-time data, the sensor allows operators to identify mechanical imbalances or bearing wear before they lead to catastrophic failure.

Reliability in Rigorous Industrial Climates

Durability remains a hallmark of the PR9268/017-100 design. The sensor features a hermetically sealed, stainless steel housing with an IP67 protection rating, making it impervious to moisture, dust, and aggressive industrial lubricants. Furthermore, it maintains a broad frequency response range from 4Hz to 10kHz, ensuring comprehensive coverage of both low-frequency structural resonances and high-frequency rotational harmonics. Because the internal electronics are optimized for temperature stability, the sensor delivers ±5% measurement consistency even when mounted on high-heat motor frames or steam turbine housings.

Streamlined System Integration and Deployment

Implementing the Emerson PR9268/017-100 into an existing DCS or vibration monitoring rack is straightforward due to its flexible installation architecture. The sensor supports multiple mounting configurations, including threaded studs and magnetic bases, allowing for permanent or temporary diagnostic use. Furthermore, the two-wire interface simplifies field wiring and reduces installation costs by utilizing loop-powered technology. As a core component of Emerson’s asset reliability portfolio, this sensor facilitates effective condition-based maintenance (CBM) strategies, ultimately increasing overall equipment effectiveness (OEE) and extending the service life of expensive industrial assets.
