Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330903-00-06-05-02-05 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330903-00-06-05-02-05 Proximity Transducer System is engineered for continuous, non-contact vibration and position measurement on rotating machinery in demanding industrial environments. Typical deployment sites include:
- Oil & Gas: Compressor trains, gas turbines, centrifugal pumps, and pipeline booster stations where shaft radial vibration and axial position must be monitored 24/7.
- Power Generation: Steam turbines, hydro generators, and combined-cycle plant rotating equipment requiring API 670-compliant monitoring.
- Petrochemical & Refining: Reactor agitators, cracked-gas compressors, and critical pump trains where unplanned downtime carries multi-million-dollar consequences.
- Marine & Offshore: Propulsion shafting and auxiliary machinery on FPSOs and offshore platforms subject to vibration-induced fatigue.
- Pulp & Paper / Mining: High-speed fans, gearboxes, and mill drives where bearing health directly impacts production throughput.

Why Engineers Specify This Model
- Exact 5 mm / 5 m configuration: The -00-06-05-02-05 suffix encodes probe tip size (5 mm), extension cable length (5 m), and armoring type — eliminating field-fit guesswork on retrofit projects.
- API 670 compliance out of the box: Meets the industry standard for machinery protection systems without additional certification work.
- Wide temperature tolerance: Probe rated to 121 °C suits hot-section turbine bearing pedestals where competing sensors fail prematurely.
- Flat frequency response to 10 kHz: Captures sub-synchronous instability, blade-pass frequencies, and gear-mesh events in a single channel.
- Direct drop-in replacement: Fully interchangeable with existing 3300 XL Proximitor® monitor racks — no recalibration of the monitor required.
- Armored extension cable: Stainless-steel armor resists mechanical damage in congested machinery skids and high-vibration environments.
Complete System Bill of Materials
A fully functional eddy-current proximity measurement loop typically requires:
- Proximity probe — 330903-00-06-05-02-05 (this item, includes probe + extension cable)
- Proximitor® Sensor / Driver — Bently Nevada 3300 XL 8mm (e.g., 330180-91-00)
- Machinery Protection Monitor — 3500 Series rack (e.g., 3500/42M Proximitor® / Velomitor® Monitor)
- Junction box / conduit fittings rated for hazardous area classification
- Shielded signal cable from Proximitor® to monitor rack
- DIN rail 24 VDC power supply (if not rack-supplied)

Compliance & Industry Standards
- API 670 – Machinery Protection Systems (5th Edition)
- ATEX Directive 2014/34/EU – Zone 1 / Zone 2 hazardous area use
- IECEx – International hazardous area certification
- CE Marking – EU electromagnetic compatibility and low-voltage directives
- ISO 10816 / ISO 20816 – Mechanical vibration evaluation of machinery
Quality Assurance & Sourcing
- Every unit is inspected against OEM datasheet specifications before shipment.
- Traceability documentation (test reports, certificates of conformance) available on request.
- Sourced from authorized distribution channels and verified surplus with full chain-of-custody records.
- Packaging preserves factory calibration — do not remove probe tip protector until installation.
How to Source This Part
- Confirm your existing Proximitor® driver model (3300 XL 5 mm or 8 mm) to ensure probe tip compatibility.
- Verify extension cable length requirement — this unit ships with a 5 m armored cable.
- Submit your purchase order or RFQ to support@konmask.com with your required delivery date.
- Request a Certificate of Conformance and calibration data sheet at time of order.
- Lead time: typically 3–7 business days for in-stock units; expedited shipping available.
Application-Specific FAQ
Q: Can this probe be used with the older 3300 (non-XL) Proximitor® sensors?
A: No. The 3300 XL series uses a revised scale factor and driver circuit. Mixing XL probes with legacy 3300 drivers will produce measurement errors. Always match probe and driver series.
Q: Is the 5 mm probe suitable for large-shaft turbines (>300 mm diameter)?
A: Yes. Shaft diameter does not affect probe selection — gap range and target material (typically 4140 steel) are the governing factors. The 330903 5 mm probe covers the standard 0.25–2.25 mm linear range required by API 670.
Q: What target material is required?
A: The probe is calibrated for AISI 4140 steel. For other shaft materials (stainless, titanium, Inconel), a material correction factor must be applied per Bently Nevada Application Note 44.
Q: Can I order just the extension cable without the probe?
A: Extension cables are available separately. Contact us with your required length and armoring specification.
Q: Do you provide installation and commissioning support?
A: We provide technical documentation and remote commissioning guidance. On-site support can be arranged through our partner network — contact us for details.
