BENTLY 330130-080-00-CN | 8 m 3300 XL Extension Cable for Proximity Probe Systems

Bently Nevada 330130-080-00-CN – 8 m 3300 XL Extension Cable for Proximity Probe Systems

The Bently Nevada 330130-080-00-CN is an 8‑meter low‑noise extension cable used in 3300 XL proximity probe systems. It links the probe to the matching Proximitor sensor to achieve the required system length and preserve calibration integrity. From my experience, getting the cable length right typically saves hours of troubleshooting and keeps the 200 mV/mil scale factor right where it should be.

Key Features

• 8 m factory‑terminated cable – Sized for common 3300 XL system length combinations without field splicing.
• Matched system performance – Designed to be used with 3300 XL probes and Proximitor sensors to maintain the nominal 200 mV/mil (≈7.87 mV/µm) scale factor.
• ClickLoc style connectors – Positive locking miniature coax connections that resist loosening under vibration.
• Low‑noise coax construction – Shielded cable helps protect low‑level eddy‑current signals from electrical interference.
• Broad probe compatibility – Works with standard 3300 XL probes (5 mm, 8 mm, 11 mm families) when the total system length is matched.
• Unarmored variant – “‑00” indicates the standard, non‑armored cable jacket, usually routed through conduit or tray.
• Regional build code – The “‑CN” suffix appears to denote a regional documentation/marking variant; electrical performance is the same.

Application Fields

You’ll find this cable anywhere a 3300 XL proximity system is protecting rotating assets:

• Gas and steam turbines – radial vibration and thrust position measurements
• Centrifugal and reciprocating compressors – bearing vibration and rod drop (with suitable brackets)
• Large pumps, fans, and blowers – API‑670 style protection channels
• Motors, generators, and gearboxes – shaft vibration/position monitoring

Advantages & Value

• Calibration integrity – Correct cable length maintains system scale factor and linear range, which typically reduces nuisance alarms.
• Reliable connectivity – Locking coax connections help prevent intermittent faults from vibration or maintenance activity.
• Procurement simplicity – Standard length and jacket keep spares straightforward and reduce stocking complexity.
• Retrofit‑friendly – Drops into existing 3300 XL probe runs without re‑engineering the rack or sensors.

Quick note from a recent turnaround: “We matched the 8 m extension with our 10 m system build, set bias near mid‑range, and vibration readings lined up with historical trends right away.”

Installation & Maintenance

• System matching – Verify the probe integral cable, this extension cable, and the Proximitor are all designated for the same total system length.
• Routing & protection – Follow minimum bend radius, avoid sharp edges, and segregate from high‑energy power cables. Use conduit or tray for the unarmored jacket.
• Grounding/shielding – Terminate shields per Bently Nevada practices to minimize electrical noise on low‑level signals.
• Connections – Fully seat and lock the connectors; a slight back‑off and re‑tighten can help confirm positive engagement.
• Commissioning – After installation, check Proximitor bias voltage and OK status, then record runout and verify measurement linearity.
• Spares – Keeping an identical length/jacket spare on hand usually shortens recovery after cable damage.

Quality & Certifications

• CE compliant; RoHS conformity for electronic assemblies in most regions
• Manufactured under ISO 9001 quality systems
• Used within API‑670 compliant protection systems when paired with certified monitors/sensors
• Manufacturer’s warranty typically 1 year; extended service programs available in many cases

If you can share the probe and Proximitor part numbers you’re pairing with 330130‑080‑00‑CN, I’ll double‑check the total system length and connector match before shipment—avoids surprises during commissioning.
