Vibration Monitoring Solution – Bently Nevada 330101-38-49-20-02-05 | 3300 XL 8mm Proximity Probe Extension Cable
Where This Product Is Used
The Bently Nevada 330101-38-49-20-02-05 extension cable is a precision-engineered interconnect component designed for continuous shaft vibration and position monitoring in rotating machinery. Engineers specify this cable in the following critical applications:
- Steam & Gas Turbines — Connects 8mm proximity probes to Bently Nevada 3300 XL monitors for real-time rotor radial vibration measurement per API 670.
- Centrifugal Compressors — Provides reliable signal transmission in high-temperature compressor casings where cable routing distance exceeds probe cable reach.
- Pumps & Gearboxes — Used in petrochemical and refinery environments to extend eddy-current probe circuits without signal degradation.
- Power Generation — Deployed in nuclear and thermal power plants for continuous online machinery protection systems.
- Marine Propulsion Systems — Installed in confined machinery spaces where flexible, shielded extension cables are required for EMI immunity.

Why Engineers Specify This Model
- Exact OEM Replacement — Drop-in compatible with existing 3300 XL probe/Proximitor® installations; no recalibration required.
- Signal Integrity — Double-shielded coaxial construction maintains eddy-current circuit linearity over the full cable run, critical for ±0.1 mil measurement accuracy.
- Harsh Environment Rated — Rated to 125°C continuous; suitable for turbine bearing pedestals and compressor seal areas.
- Flexible Routing — Armored yet flexible jacket allows installation in tight conduit runs and cable trays common in turbomachinery skids.
- Reduced Downtime — Pre-terminated and factory-tested; plug-and-play replacement minimizes outage windows during planned maintenance.
Complete System Bill of Materials
For a complete Bently Nevada 3300 XL 8mm eddy-current measurement loop, the following components are typically required:
- Proximity Probe — e.g., Bently Nevada 330103-00-08-10-02-00 (8mm, 5m integral cable)
- Extension Cable — 330101-38-49-20-02-05 (this item)
- Proximitor® Sensor — e.g., Bently Nevada 330180-X1-05 (3300 XL driver)
- Monitor Module — Bently Nevada 3500/40M or 3300 XL rack-mount monitor
- Junction Box / Conduit Fittings — site-specific, customer-supplied
Compliance & Industry Standards

Application-Specific FAQ
Q: Is the 330101-38-49-20-02-05 compatible with older 3300 series (non-XL) probes?
A: This cable is optimized for the 3300 XL 8mm system. Compatibility with legacy 3300 (non-XL) probes depends on connector type — contact us with your existing probe part number for confirmation.
Q: Can this extension cable be used in hazardous (Ex) classified areas?
A: The standard 330101 series is not intrinsically safe rated. For ATEX/IECEx Zone 1 or Zone 2 installations, consult Bently Nevada’s hazardous area probe documentation or contact Konmask for compliant alternatives.
Q: What is the maximum total system cable length for the 3300 XL 8mm system?
A: Bently Nevada specifies a maximum total cable length (probe + extension) of 9 meters (30 ft) for standard gap range. Exceeding this affects the linear measurement range — always verify against your Proximitor® sensor datasheet.
Q: Do you offer custom cable lengths or connector configurations?
A: Yes. Contact us with your required length and connector specification; we can source or cross-reference alternative 330101 part numbers to match your installation requirements.
Q: What documentation is available with this part?
A: We provide a packing list and, upon request, a certificate of conformance. Bently Nevada’s official installation manual (document 141536-01) is available from Baker Hughes / Bently Nevada’s technical library.
