Bently Nevada 330905-06-14-10-02-00 – Proximity Probe/Cable Assembly for 3300/3500 Vibration Monitoring

The Bently Nevada 330905-06-14-10-02-00 is part of the 3300-series proximity measurement chain used in 3300 and 3500 racks. In many cases this build code corresponds to a proximity probe and integral cable configuration that mates with a matching 3300/3300 XL Proximitor sensor to measure shaft vibration, axial position, or Keyphasor speed reference. From my experience, the 3309xx family is chosen when an end user needs dependable eddy-current displacement measurements around rotating equipment—compressors, steam/gas turbines, critical pumps, blowers, and gearboxes—while maintaining API 670-style practices and long-term stability.

Our Order Process & Guarantees

• Delivery: Typically 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Non-contact eddy-current sensing – Measures shaft vibration and position without mechanical contact, minimizing wear.
• Matched to 3300/3300 XL Proximitor sensors – Ensures the system delivers the standard scale factor (typically 200 mV/mil, 7.87 mV/µm) and linearity when components are correctly paired.
• Industrial build for harsh environments – Rugged probe and cable construction suited to high-temperature machinery spaces and continuous-duty operation.
• API 670-style application practice – Widely used on turbomachinery compliance projects where repeatability and traceability matter.
• Flexible mounting options – Commonly installed through probe holders or brackets for radial vibration, axial position, or Keyphasor indexing.
• Backward compatibility – Works with established Bently Nevada 3300/3500 ecosystem in most cases, easing spares and maintenance.

Technical Specifications

Application Fields

You’ll typically see the 330905-06-14-10-02-00 in vibration and position measurement loops on:

• Steam/gas turbines – radial vibration and thrust position monitoring
• Compressors and expanders – shaft vibration and Keyphasor reference
• API 610/ISO 13709 pumps – bearing housing radial probes and axial position
• Gearboxes and motors – condition monitoring and phase/speed pickup
• Fans/blowers – trend monitoring to reduce unplanned downtime

One maintenance lead told us their 3500 rack readings stabilized after swapping to a matched 3300/3300 XL probe/cable set; it seems to be the pairing that makes the scale factor and linear range behave exactly as expected during turnarounds.

Advantages & Value

• Reliability – Proven hardware for continuous-duty turbomachinery. Fewer nuisance trips when the probe/cable/driver are correctly matched.
• Compatibility – Integrates with 3300 and 3500 monitoring systems, typically without re-engineering.
• Lifecycle savings – Stable calibration reduces commissioning time; fewer repeat gap/scale adjustments during outages.
• Supportability – Clear traceability via build code; easy to replace like-for-like spares across units and sites.

Installation & Maintenance

• Panel/cabinet – Mount Proximitor in a ventilated enclosure; observe grounding and shielding best practices to minimize EMI.
• Probe mounting – Use the proper holder/bracket; set the probe gap with a feeler gauge or micrometer kit. You might notice big improvements by keeping the target surface clean and concentric.
• Cable routing – Separate probe cables from power conductors; avoid tight bend radii and hot spots near process piping.
• Safety – Lockout/tagout rotating equipment. Verify hazardous-area approvals for your suffix code before entering classified zones.
• Routine checks – Periodic scale-factor verification (200 mV/mil typical) on the Proximitor output, connector integrity checks, and cleaning of probe tips during scheduled outages.
• Firmware/monitor – Keep 3300/3500 monitor firmware current and document any alarm setpoint changes after maintenance.

Quality & Certifications

• Manufacturing under ISO 9001 quality systems (typical for Bently Nevada)
• CE compliance and RoHS conformity are commonly available
• Hazardous-area approvals (e.g., ATEX/IECEx/CSA) may apply depending on the exact suffix build
• Warranty: 12 months from shipment

If you’re matching this 330905-06-14-10-02-00 to an existing loop, share the Proximitor model and the intended gap/target material. We typically confirm the scale factor and linear range to ensure your readings line up with plant standards without extra tuning.
