Bently Nevada 330907-05-30-10-02-05 – Proximitor Sensor for Shaft Vibration and Position Monitoring

The Bently Nevada 330907-05-30-10-02-05 is part of the 3300 XL Proximity Transducer family typically used for non-contact measurement of shaft vibration, axial position, and rotor-to-stator clearance on critical rotating assets. It interfaces a proximity probe and extension cable to your monitoring system, delivering a clean dynamic vibration signal plus a DC gap (position) voltage. From my experience, the 330907 is chosen as a reliable drop-in for 3300/3500 racks when plants want stable measurements and proven EMI immunity in tough areas around turbines, compressors, pumps, and gearboxes.

Key Features

• Proximitor transducer (eddy-current) – Converts probe signal into dynamic vibration and DC gap outputs for monitors or PLCs.
• Compatible with 3300/3500 systems – Designed to work with Bently Nevada rack monitors in most cases, minimizing engineering effort.
• Industry-standard scale factor – Typically 200 mV/mil (≈7.87 mV/μm) for consistent vibration and displacement trending.
• Robust noise immunity – Shielded input and grounded architecture help in high-EMI environments near large motors or VFDs.
• Option-coded build – The -05-30-10-02-05 code defines specifics such as cable/probe pairing and approvals; we can verify exact build against your installed base.
• Harsh-duty construction – Potted module for field mounting or cabinet installation where temperature and vibration are a concern.

Technical Specifications

Application Fields

You might notice that plants typically deploy the 330907 on high-value rotating assets where early warning matters:

• Steam and gas turbines (radial vibration, differential expansion, shaft position)
• Compressors and expanders (bearing vibration, axial thrust monitoring)
• Pumps and fans (unbalance/looseness detection, clearance checks)
• Gearboxes and generators (shaft motion, casing dynamics via proximity targets)
• API 670 environments where non-contact displacement is required

Advantages & Value

• Reliability – Stable bias and dynamic signals reduce nuisance alarms in most cases.
• Compatibility – Works with established 3300/3500 racks; easy drop-in for replacements or expansions.
• Lifecycle savings – Consistent scaling simplifies setup and trending, saving commissioning time.
• Supportable – Clear option coding; spares and accessories are straightforward to match.

Installation & Maintenance

• Mounting – Install the Proximitor on a rigid surface (cabinet backplate or near-machine bracket). Maintain proper grounding; avoid mounting next to high-current contactors when possible.
• Wiring – Use the specified Bently Nevada probe and extension cable; keep cable runs continuous (no splices). Terminate shields per the manual to control noise.
• Ventilation – In enclosures, allow airflow and avoid hot spots; keep ambient within the stated temperature range.
• Setup – Set the probe-to-target gap, then verify DC bias and dynamic signal at the monitor. From my experience, a quick bias check with a DMM catches most issues.
• Routine care – Inspect cable integrity, clean connectors, and tighten terminals during outages. Confirm scaling and alarm setpoints after any maintenance.
• Firmware/monitor updates – While the Proximitor is analog, keeping your 3500/3300 monitor firmware current improves diagnostics and trending.

Quality & Certifications

• CE compliant and RoHS in most configurations
• UL/cUL recognition may apply by option code or system; documentation available on request
• Manufacturer warranty coverage typically aligns with the 365-day sales warranty

Recommended Accessories & Compatible Components

To ensure correct scaling and linear range, pair the 330907 with matching probes and extension cables. We can cross-check your installed base to confirm exact options.

• 3300 XL Proximity Probes – 8 mm and 11 mm variants for standard AISI 4140 steel targets; selected by thread, tip style, and length.
• 3300 XL Extension Cables – Lengths to match your proximity probe per option code; maintain factory calibration by using correct lengths.
• Monitor Racks – Bently Nevada 3500/3300 modules for vibration, thrust, and position channels using Proximitor inputs.
• Mounting hardware – Brackets, clips, and shielded cable accessories to improve installation robustness.

One thing I appreciate is how predictable the setup tends to be when the probe and cable lengths match the option code—calibration usually lands right on spec. If you share your option breakdown for 330907-05-30-10-02-05, we’ll verify exact range and scaling before shipment, so the unit goes in and runs without surprises.
