Bently Nevada 330130-040-02-05 – 4-Meter Extension Cable for Proximity Probes | 3300 XL Series
Engineering Background: The Bently Nevada 3300 XL Series represents the industry benchmark for non-contacting proximity measurement in rotating machinery protection. Designed for continuous operation in harsh industrial environments, the 3300 XL system relies on a precisely matched three-component chain: probe, extension cable, and proximitor. The 330130-040-02-05 is the OEM-specified 4-meter (13.1 ft) extension cable engineered to complete this chain with zero signal compromise.
Product Positioning: This extension cable is the critical signal conduit between the eddy-current probe tip and the proximitor module. It maintains the calibrated electrical characteristics required for accurate gap voltage output, making it indispensable for turbines, compressors, pumps, and gearboxes operating under API 670 machinery protection standards. Procurement engineers sourcing replacement or spare cables for 3300 XL installations will find this part fully interchangeable with OEM-installed units.

- Wide Temperature Range: Rated to +121 °C continuous, suitable for hot-section installations near turbine casings and exhaust ducts.
- Drop-In Replacement: Identical form, fit, and function to OEM-installed cables — no system re-ranging or reconfiguration required.
System Architecture & Signal Flow
The 3300 XL proximity measurement chain operates as follows:
Probe Tip (330100 series) → Extension Cable 330130-040-02-05 (this item) → Proximitor Module (330180 series) → Monitor / Rack (3500 or 3300 series)
The extension cable carries the RF oscillator signal from the proximitor to the probe and returns the modulated gap-dependent signal back. Any impedance mismatch or cable degradation directly corrupts the gap voltage output. Using the correct OEM part number is therefore a system integrity requirement, not merely a preference.
Sourcing & Quality Verification
- All units sourced through authorized industrial automation distributors or verified surplus channels with full traceability documentation.
- Each cable is inspected for connector integrity, jacket condition, and continuity prior to shipment.
- Certificates of conformance and original manufacturer documentation available upon request for critical plant applications.
- Konmask.com maintains inventory of common 3300 XL cable lengths and connector configurations to support urgent MRO requirements.
Procurement Process
- Step 1: Confirm your installed probe series and proximitor model to verify cable compatibility.
- Step 2: Verify required cable length (this listing: 4.0 m / -040 code). Other lengths available — contact us.
- Step 3: Place order online or contact support@konmask.com for volume pricing, expedited shipping, or documentation packages.
- Step 4: Receive with inspection report; install as direct OEM replacement with no system adjustments required.
Technical FAQ
Q: Can I use a generic coaxial cable instead of the OEM 330130 series?
A: No. The 3300 XL system is calibrated as a matched set. Non-OEM cables alter the system’s electrical length and impedance, causing sensitivity errors that invalidate machinery protection setpoints. Always use the specified Bently Nevada part number.
Q: What is the difference between connector codes -01, -02, and -03?
A: The connector code specifies the termination style at each end of the cable. Code -02 is the standard configuration for most 3300 XL field installations. Contact us if you require a different connector configuration.
Q: Is this cable compatible with the older 3300/5 or 3300/16 systems?
A: The 330130 series is designed for the 3300 XL platform. Compatibility with legacy 3300/5 or 3300/16 systems depends on the specific proximitor model. Consult the Bently Nevada system compatibility matrix or contact our technical team before ordering.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For large quantity orders or documentation-intensive plant requirements, contact us for a formal quotation.
