Bently Nevada 330130-085-12-00 – Standard Extension Cable | 3300 Series Proximity System
Engineering Background: In rotating machinery protection systems, the signal path between a proximity probe and its driver is mission-critical. A degraded or non-compliant extension cable introduces impedance mismatches, signal attenuation, and ground loops — any of which can trigger false trips, mask real vibration events, or cause catastrophic undetected failures in turbines, compressors, and pumps. The Bently Nevada 330130-085-12-00 Standard Extension Cable is the precision-engineered link that ensures signal integrity is never compromised.
Product Positioning: The 330130-085-12-00 is a factory-specified extension cable within the Bently Nevada 3300 Series proximity transducer system — one of the most widely deployed machinery protection platforms in the global oil & gas, power generation, and petrochemical industries. This cable bridges the proximity probe (typically 330100/330101 series) to the Proximitor® sensor, completing the eddy-current measurement loop with OEM-defined electrical characteristics. Its 8.5-meter (approximately 28-foot) length addresses the most common installation geometry in large rotating equipment enclosures.

System Architecture & Signal Flow
The 3300 Series proximity measurement chain follows a defined topology:
Proximity Probe (330100/330101) → Extension Cable (330130-085-12-00) → Proximitor® Sensor (3300 XL / 3300 NSv) → System 1® / 3500 Rack Monitor
The extension cable carries the RF oscillator signal from the Proximitor® to the probe tip, and returns the demodulated DC voltage proportional to gap distance. Cable length directly affects system sensitivity scaling — the 8.5 m variant is factory-calibrated for use with standard 5 mm and 8 mm probe tip configurations. Substituting non-OEM cables of different capacitance will shift the output scale factor and invalidate API 670 compliance.

Technical FAQ
- Q: Can the 330130-085-12-00 be used with non-Bently Nevada Proximitor® sensors?
- A: No. This cable is designed and calibrated specifically for the Bently Nevada 3300 Series system. Using it with third-party sensors will produce incorrect output scaling and may void system certification.
- Q: What is the difference between the 330130 and 330180 extension cable series?
- A: The 330130 series uses standard coaxial construction for general industrial environments. The 330180 series is armored for high-mechanical-stress or high-temperature routing paths. Consult your system drawing to confirm the correct variant.
- Q: Is the 8.5 m length field-trimmable?
- A: No. Cutting or splicing the extension cable changes its electrical length and capacitance, which directly affects Proximitor® output scaling. Always order the correct factory-specified length.
- Q: Do you supply the matching probe and Proximitor® sensor as a complete kit?
- A: Yes. Konmask.com can source complete 3300 Series transducer kits including probe, extension cable, and Proximitor® sensor. Contact us with your system configuration for a bundled quote.
- Q: What certifications apply to this cable?
- A: The 330130-085-12-00 is manufactured to Bently Nevada internal quality standards and supports API 670 compliant machinery protection system installations when used as specified.
