Rotating Machinery Vibration Monitoring Solution – BENTLY NEVADA 330130-070-00-CN | 3300 XL Series
The Bently Nevada 330130-070-00-CN is a 7-metre (70-foot) extension cable engineered for use within the 3300 XL Proximity Transducer System. It bridges the gap between the proximity probe and the Proximitor® sensor, enabling precise non-contact displacement and vibration measurement on rotating shafts in critical industrial machinery. Procurement engineers and reliability teams worldwide specify this cable to maintain signal integrity across demanding installation geometries.
Where This Product Is Used
This extension cable is a mandatory system component wherever the standard probe cable length is insufficient to reach the Proximitor® sensor. Typical deployment environments include:
- Steam & Gas Turbines — shaft radial vibration and axial position monitoring per API 670
- Centrifugal Compressors — bearing journal orbit analysis in petrochemical and LNG trains
- Boiler Feed Pumps & Large Centrifugal Pumps — continuous displacement monitoring in power generation
- Gearboxes & Expanders — high-speed shaft monitoring in refinery and chemical plant service
- Motor-Driven Equipment — rotor dynamic surveillance in critical rotating assets
- Marine Propulsion Systems — shaft monitoring in confined machinery spaces requiring extended cable routing
Wherever a 3300 XL proximity probe is installed more than the standard cable length from its Proximitor® sensor, the 330130-070-00-CN provides the calibrated electrical extension required to preserve system accuracy.

Why Engineers Specify This Model
- Calibrated System Matching — The 330130 extension cable is factory-characterized to maintain the electrical properties of the 3300 XL eddy-current loop. Substituting generic coaxial cable invalidates system calibration and voids OEM warranty.
- 7-Metre Reach — The -070 length designation covers the most common installation gap between probe tip and Proximitor® sensor in large turbomachinery pedestals and compressor trains.
- Armored Construction — Stainless steel armor protects against mechanical damage, rodent ingress, and vibration-induced fatigue in high-cycle environments.
- Drop-In Replacement — Identical form, fit, and function to OEM-supplied cables; no recalibration required when replacing like-for-like.
- Hazardous Area Compatibility — Compatible with ATEX/IECEx-certified Proximitor® sensors when installed per Bently Nevada system documentation.

Application-Specific FAQ
- Q: Can I use a generic coaxial cable instead of the 330130-070-00-CN?
- A: No. The 3300 XL system is a calibrated eddy-current loop. The probe, extension cable, and Proximitor® sensor are characterized together. Using a non-OEM cable alters the system’s electrical characteristics, shifts the calibration curve, and will produce inaccurate vibration readings. It also violates API 670 compliance requirements.
- Q: What is the difference between 330130-070-00-00 and 330130-070-00-CN?
- A: The final suffix (-00 vs -CN) denotes the regional configuration. The -CN variant is the standard configuration for the China market and is electrically identical to the -00 variant. Both are fully interchangeable in the 3300 XL system.
- Q: Can this cable be used with 3300 NSv or 3300 RAM probes?
- A: The 330130 extension cable is designed for the standard 3300 XL eddy-current system. Compatibility with NSv or RAM variants depends on the specific Proximitor® sensor. Contact our technical team to confirm compatibility for your exact system configuration.
- Q: What is the maximum total cable length (probe cable + extension cable) for the 3300 XL system?
- A: Bently Nevada specifies a maximum total cable length of 9.0 m (30 ft) for the standard 3300 XL system. The 330130-070-00-CN (7 m) is typically paired with a 2 m probe cable to reach this limit. Consult Bently Nevada document 141536-01 for full cable length specifications.
- Q: Do you provide a certificate of conformance with the shipment?
- A: Yes. A certificate of conformance (CoC) and packing list are included with every shipment. Batch traceability documentation is available on request for critical plant applications.
- Q: What is the lead time for the 330130-070-00-CN?
- A: In-stock units ship within 3–5 business days. For out-of-stock situations, typical lead time is 4–8 weeks depending on OEM availability. Contact us for real-time stock status.
