Description
Overview
The PR9268/300‑000 eddy current sensor module from Emerson’s EPRO series is designed for high‑accuracy vibration and displacement monitoring on rotating machinery. Built for long‑term reliability in demanding industrial environments, the sensor provides stable, repeatable measurements essential for machinery protection and predictive maintenance programs.
Functional Characteristics
The PR9268/300‑000 functions as a non‑contact displacement and vibration sensor using eddy current technology. Its stainless‑steel housing and sealed construction support continuous operation in areas exposed to moisture, dust, corrosive gases, and high vibration levels. The sensor is engineered to maintain measurement stability even in electrically noisy environments, making it suitable for integration into DCS‑based monitoring systems.
The module delivers a consistent 4–20 mA output signal proportional to vibration velocity, enabling compatibility with a wide range of monitoring platforms. Its broad frequency response supports early detection of mechanical faults such as imbalance, misalignment, and bearing degradation.
