EPRO PR 9268/601-000 – Industrial IEPE Accelerometer for Reliable Machinery Vibration Monitoring

The EPRO PR 9268/601-000 is a rugged, IEPE (ICP-type) accelerometer designed for continuous condition monitoring on rotating equipment—motors, pumps, compressors, gearboxes, and fans. From my experience, this series is used when you need stable, low-noise vibration data tied into a plant’s online protection or route-based systems. You might notice that it’s built for harsh environments and straightforward to integrate with standard IEPE inputs on most monitoring platforms.

Key Features

• IEPE (ICP) compatibility – Powered by a constant current source and outputs a clean AC voltage, so it drops straight into most condition monitoring systems.
• Industrial-grade construction – Stainless-steel, hermetically sealed design typically suited for continuous service in oily and humid areas.
• Stable, low-noise signal – Helps trend bearing and gear mesh issues early, reducing false alarms and “chasing noise.”
• Stud-mount design – Rigid mounting for better high-frequency response on critical points like bearing housings.
• Wide application window – Commonly used on motors 5 kW and up, as well as high-load gearboxes and fans that need reliable spectral data.
• Simple cable infrastructure – Works with standard IEPE coax or ruggedized field cables to BNC or screw terminals in junction boxes.

• IEPE field cables and junction boxes – Ruggedized coax or twisted-pair IEPE cabling to BNC or screw terminal panels for routing to the monitor.

Installation & Maintenance

• Mounting surface: Machine a flat spot; remove paint and oxidation. A thin layer of mounting grease typically improves high-frequency coupling.
• Stud torque: Tighten to the recommended torque for the selected thread (in many cases 2–8 N·m). Avoid overtightening on thin housings.
• Cable routing: Use secured runs to reduce movement and triboelectric noise; keep away from VFD power cables where possible.
• Enclosure integration: If signals land in a cabinet, use grounded metal enclosures with proper strain relief and, ideally, shielded feedthroughs.
• Powering: Provide an IEPE constant-current source per channel (typ. 2–10 mA) with adequate compliance voltage.
• Safety: De-energize nearby equipment during installation. For hazardous areas, verify the exact PR 9268 variant approvals before use.
• Routine checks: Visual inspection of connectors and cables every quarter; re-torque mounts after thermal cycles or major outages.
• Calibration: Functional test annually on a reference shaker; record sensitivity drift to keep baselines consistent across routes.
• Cleaning: Wipe the sensor body and connector with lint-free cloth; avoid solvents that may attack seals.

Feedback from maintenance teams is usually consistent: once the mounting is right, the PR 9268 series delivers stable spectra over long intervals and simplifies fault trending—bearing outer race and gear mesh issues, in particular, tend to stand out earlier.

Quality & Certifications

• Certifications: CE and RoHS compliant; ATEX/IECEx versions are typically available depending on the exact sub-variant.
• Manufacturing quality: Factory calibration certificate available upon request for QA documentation.
• Warranty: 365 days (our supply guarantee)
