Description
Bently Nevada 330104-03-13-10-01-00 – Extension Cable for 3300 XL 8 mm Proximity Transducer Systems
The Bently Nevada 330104-03-13-10-01-00 is an original 3300 XL extension cable designed to link a 330103 8 mm proximity probe to a 3300 XL Proximitor Sensor. From my experience, getting the right cable configuration is just as critical as the probe itself—this is what keeps your vibration and shaft position signals stable, noise-free, and within calibration.
Typical applications include steam and gas turbines, centrifugal compressors, pumps, generators, and large motors. If you’re standardizing on the 5 m / 7 m / 9 m 3300 XL system lengths, this cable configuration fits right into that ecosystem.
Key Features
- Purpose-built for 3300 XL 8 mm systems – Mates between the 330103 probe and the 3300 XL Proximitor Sensor to maintain calibrated system length and linearity.
- Factory-matched signal performance – The cable impedance and capacitance are tuned for accurate gap and vibration measurements, which typically reduces drift and noise.
- Reliable connectors – Keyed, secure-click mini-coax style terminations help prevent mis-mating during maintenance turnarounds.
- Industrial-grade materials – Fluoropolymer (PFA) outer jacket provides chemical resistance and long-term durability in oil and gas, power, and process environments.
- Supports standard system lengths – Works with commonly used 5 m, 7 m, and 9 m 3300 XL transducer system configurations.
- Drop-in replacement – Ideal for planned outages where fast, one-for-one swap keeps machine protection channels online.

Application Fields
You might notice this cable most often in rotating equipment protection and condition monitoring:
- Steam and gas turbines (radial vibration and axial position measurements)
- Centrifugal and screw compressors in upstream/midstream oil & gas
- High-voltage generators and large induction/synchronous motors
- Critical pumps, fans, and gearboxes in power and chemical plants
“Swapping the 330104 cable during our outage cleared a persistent noise issue on two compressor bearings,” a maintenance lead told me. That’s typical when the old jacket has seen heat and oil for years.
Advantages & Value
- Measurement integrity – Matched cable characteristics help keep gap voltage and vibration amplitudes within spec, especially over longer runs.
- Compatibility assurance – Designed to work seamlessly with the 330103 probe and 3300 XL Proximitor Sensor; no field “tuning” guesswork.
- Reduced downtime risk – Quick, like-for-like replacement lowers turnaround risk and typically avoids channel reconfiguration.
- Lifecycle support – Easy to keep as spares; commonly stocked for turbine/compressor trains where availability matters.

Installation & Maintenance
Routing – Keep the cable in metallic conduit or tray where possible. Separate from high-voltage and VFD cables to minimize induced noise.
- Bend radius – Avoid tight bends; use a gentle radius to prevent conductor or shield damage (a larger-than-cable-diameter radius is typically safe practice).
- Connections – Ensure connectors are fully seated and keyed correctly at the probe and Proximitor ends; finger-tight, then secure per site standards.
- Cabinets – Mount the Proximitor Sensor in a ventilated cabinet (NEMA/IEC equivalent) with clean grounding practices for stable measurements.
- Inspection – Periodically check for jacket abrasion, crushed sections, or oil ingress. Replace on any visible damage or intermittent channel behavior.
- Calibration checks – After cable replacement, verify gap voltage and scale factors at the rack or monitoring system; adjustments are rarely needed if lengths match.
Quality & Certifications
- Compliance – CE and RoHS conformant components are typically used in the 3300 XL transducer family.
- Manufacturing – Produced under controlled quality systems (commonly ISO 9001 environments).
- Warranty – Standard manufacturer warranty terms apply for new, original parts.
