Bently Nevada 330130-080-01-00 – 3300 XL Extension Cable | 3300 XL Proximity Transducer System
Engineering Background
The Bently Nevada 3300 XL Proximity Transducer System is the industry benchmark for non-contact vibration and position measurement in rotating machinery. Deployed across gas turbines, steam turbines, compressors, and pumps worldwide, the 3300 XL platform demands precision-matched cabling to maintain signal integrity across the full measurement chain.
Product Positioning
The 330130-080-01-00 is an 8.0-meter extension cable engineered specifically for the 3300 XL series. It bridges the proximity probe (330100/330101 series) to the Proximitor® sensor, ensuring low-loss signal transmission in harsh industrial environments. This part is the OEM-specified drop-in replacement for maintenance, retrofit, and new installation projects.

Engineering Advantages
- Signal Integrity – Precision 50 Ω impedance matching eliminates reflection errors across the 8.0 m run
- EMI Shielding – Double-shielded construction rejects electrical noise in VFD-dense environments
- Mechanical Durability – Stainless steel armor withstands vibration, abrasion, and chemical exposure
- OEM Compatibility – Direct replacement; no recalibration of Proximitor® sensor required
- Temperature Stability – PTFE dielectric maintains consistent electrical characteristics from -40°C to +85°C
- API 670 Compliant – Meets machinery protection standard for critical rotating equipment
System Architecture & Signal Flow
The 3300 XL measurement chain follows a three-component topology:
- Proximity Probe (330100/330101 series) → generates eddy-current field at shaft surface
- Extension Cable 330130-080-01-00 → transmits raw probe signal with minimal attenuation
- Proximitor® Sensor (330180 series) → conditions signal to –24 VDC output for monitor input
The 8.0 m cable length is factory-calibrated as part of the system. Substituting non-OEM cables alters the total system inductance and capacitance, causing scale factor errors and false alarms. Always specify the correct length code (-080-) when ordering.

Technical FAQ
Q: Can I use a different cable length with my existing Proximitor® sensor?
A: No. The Proximitor® sensor is factory-calibrated for a specific probe + cable length combination. Changing the cable length requires recalibration or a new matched system.
Q: What is the difference between 330130-080-01-00 and 330130-080-00-00?
A: The last two digits denote the armor/jacket option. -01-00 includes stainless steel armor; -00-00 is unarmored. Specify -01-00 for installations with mechanical exposure risk.
Q: Is this cable compatible with 3300 NSv or 3500 series monitors?
A: The 330130 series is designed for 3300 XL Proximitor® sensors. Compatibility with 3300 NSv requires verification of the Proximitor® model. It is not interchangeable with 3500 series transducer cables.
Q: Do you provide ATEX/IECEx certified versions?
A: Hazardous-area certified variants are available. Contact us with your area classification (Zone/Division) and we will confirm the correct suffix.
Q: What is the minimum order quantity?
A: Single-unit orders accepted. Volume pricing available for 5+ units.
