Condition Monitoring Solution — EMERSON PR9268/617-100-CNS | PR9268 Series
Where This Product Is Used
The EMERSON PR9268/617-100-CNS is an eddy current proximity probe sensor engineered for continuous vibration and displacement monitoring of rotating machinery in demanding industrial environments. Typical deployment sites include:
- Steam & Gas Turbines — shaft radial vibration and axial position measurement per API 670
- Centrifugal Compressors — real-time rotor orbit tracking in petrochemical and LNG plants
- Pumps & Fans — early-warning bearing fault detection in power generation and water treatment
- Gearboxes — gear mesh frequency monitoring in steel mills and cement plants
- Marine Propulsion Systems — shaft displacement monitoring in offshore platforms
- DCS / Safety Instrumented Systems (SIS) — integrated with Emerson DeltaV, Honeywell Experion, or ABB 800xA for automated trip logic

Why Engineers Specify This Model
- Drop-in Bently Nevada 3300 compatibility — same sensitivity (8 mV/µm) and gap range, enabling direct replacement without recalibration of existing monitoring racks
- Armored integral cable — eliminates field-splice failure points common in high-vibration environments
- CNS connector — industry-standard coaxial termination for fast, tool-free swap-out during planned outages
- Wide temperature range — qualified for hot-section turbine bearing pedestals and cryogenic compressor applications
- Proven EMERSON / Epro lineage — traceable calibration certificates available; preferred by OEM machinery builders worldwide

Application-Specific FAQ
Q: Is the PR9268/617-100-CNS a direct replacement for Bently Nevada 330101 probes?
A: Yes. The PR9268 series uses the same 8 mV/µm sensitivity and −24 VDC supply, making it electrically compatible with Bently Nevada 3300 and 3500 monitoring systems without driver reconfiguration.
Q: What does “617-100” in the part number mean?
A: “617” denotes the probe body diameter/style code, and “100” indicates the integral cable length of 100 inches (≈ 2.54 m). Always verify cable length matches your probe-to-driver distance before ordering.
Q: Can this sensor be used in hazardous (Ex) areas?
A: The standard CNS variant is not ATEX-rated. For Zone 1/Zone 2 installations, request the intrinsically safe variant or use an approved Zener barrier in the signal loop.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock situations, typical lead time is 2–4 weeks. Contact us for real-time availability.
Q: Do you provide calibration certificates?
A: Yes, traceable calibration documentation is available upon request at time of order.
