Bently Nevada 330130-045-01-CN 3300 XL Standard Extension Cable with 4.5-meter Armored Design Gold-Plated ClickLoc Connectors and API 670 Compliance

The Bently Nevada 330130-045-01-CN is a 4.5m armored extension cable for the 3300 XL 8mm proximity system. It connects the probe and Proximitor, mainly for eddy current sensor cable signal transmission. It uses 75Ω Coaxial cable design with triaxial ClickLoc connectors, plus NEPSI certified proximity cable approval.

Yes, electrically it’s the same as 330130-045-00-CN. So in most cases it works as a drop-in eddy current sensor replacement cable. The difference is protection. This one has stainless steel armor wrapping, which helps in high-vibration rotating machinery monitoring where cables can get hit or squeezed.

In steam turbine vibration monitoring or centrifugal compressor protection systems, signal stability is important. This cable uses triaxial shielding + ClickLoc connectors, which helps keep low-attenuation high-frequency RF signals stable into the 3500/40M Proximitor Monitor inside a 3500 rack module system. In practice, it helps avoid noise-related false alarms.

Nothing too complex, but a few basics matter. Keep the total system electrical length matched with the probe and Proximitor setup. And don’t bend it tighter than the 25.4 mm minimum bend radius, especially near turbine or compressor areas. That’s usually enough to keep the 3300 XL Extension Cable performing stable in long-term use.

The “CN” version is aligned with NEPSI hazardous area approval and China certification requirements. In real projects like petrochemical plants, power plant instrumentation, or intrinsically safe deployments in China, this version is often preferred because it passes compliance checks more directly.
