Description
Overview
The PR9268/017‑100 mechanical velocity sensor from Emerson’s EPRO series is a precision electrodynamic vibration sensor engineered for continuous monitoring of rotating machinery. Designed for long‑term reliability in harsh industrial environments, the sensor provides stable velocity measurements essential for predictive maintenance and machinery protection systems.
Functional Characteristics
The PR9268/017‑100 operates as an electrodynamic velocity transducer, converting mechanical vibration into a proportional electrical signal. Its construction supports consistent performance under high vibration loads, making it suitable for pumps, motors, fans, compressors, and other critical rotating assets. The sensor’s sealed housing ensures dependable operation in areas exposed to dust, moisture, and mechanical shock.
The device offers a linear output across a broad frequency range, enabling accurate detection of imbalance, misalignment, looseness, and other mechanical faults. Its two‑wire loop‑powered design simplifies integration with DCS and condition monitoring systems.
