Bently Nevada 330130-040-03-05 Extension Cable – 3300 XL Proximitor® Series
Imagine a critical rotating machine — a high-speed compressor or steam turbine — running without a reliable signal path between its proximity probe and the monitoring system. Without a properly rated, OEM-specified extension cable, the entire vibration monitoring chain collapses: signal attenuation, ground loops, and false alarms become inevitable, leaving maintenance engineers blind to shaft displacement events that precede catastrophic failure. The Bently Nevada 330130-040-03-05 Extension Cable is the precision-engineered link that keeps this chain intact.
Within the 3300 Series ecosystem — Bently Nevada’s globally dominant platform for machinery protection and condition monitoring — the 330130-040-03-05 represents the 4-metre (approximately 13-foot) extension cable variant, designed to bridge the gap between the proximity probe and the Proximitor® sensor in installations where direct mounting is not feasible. Deployed across refineries, power generation facilities, and petrochemical plants on every continent, this cable is a non-negotiable component in any compliant API 670 monitoring installation.

If you are unsure which cable length or connector variant is required for your installation, our technical team can cross-reference your existing probe assembly part number and advise accordingly.
Our Quality Assurance Process
- Source Verification: All units are procured exclusively from authorised distributors, OEM surplus channels, or verified industrial decommissioning projects — never from unvetted grey-market brokers.
- Physical Inspection: Connectors, cable jacket, and labelling are inspected against Bently Nevada published drawings for dimensional and cosmetic conformance.
- Continuity & Impedance Test: Each cable is bench-tested for end-to-end continuity and shield integrity before packaging.
- Documentation Package: Shipments include a Konmask.com inspection report and, where available, original manufacturer documentation or traceability records.

Frequently Asked Questions
Q: Is the 330130-040-03-05 compatible with the older 3300 (non-XL) Proximitor® sensors?
A: The 330130 series extension cables are primarily specified for the 3300 XL platform. Compatibility with legacy 3300 sensors depends on the connector variant (suffix -03 vs -05). Please contact us with your full system part numbers for confirmation.
Q: Can I use a longer or shorter extension cable without recalibrating the Proximitor®?
A: No. The total system cable length (probe cable + extension cable) must match the Proximitor® sensor’s calibrated system length. Changing cable length requires recalibration or selection of a Proximitor® calibrated for the new total length.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A Konmask.com inspection and conformance report is included with every shipment. Original manufacturer CoC is provided where available from our supply chain.
Q: What is the lead time if the item is not in stock?
A: Typical sourcing lead time is 7–15 business days. For urgent shutdowns, contact us directly — we maintain relationships with multiple authorised surplus channels globally.
Q: Can you supply multiple units for a plant-wide spares programme?
A: Yes. Volume pricing is available for orders of 5 units or more. Contact us for a formal quotation.
