BENTLY NEVADA 330930-060-01-05 – 6 m Extension Cable for 3300 Series Proximity Sensing

The BENTLY NEVADA 330930-060-01-05 is, in most cases, supplied as a 6.0 m factory-terminated extension cable for 3300/3300 XL proximity probe systems. It’s the piece that quietly ensures low-noise signal transmission between the probe and the Proximitor sensor, which is why maintenance teams tend to keep a few on the shelf. One thing I appreciate is how these assemblies reduce installation time—no field terminations to fuss over, just route, connect, and verify gap readings.

Our Order Process and Guarantees

• Express options: FedEx, UPS, DHL

Key Features

• 6.0 m factory-terminated length – Typically supplied ready to install, saving time and avoiding termination errors.
• Low-noise signal path – Designed for stable eddy-current probe signals between probe and Proximitor.
• 3300/3300 XL ecosystem compatibility – Usually used with Bently Nevada proximity probes and Proximitor sensors.
• Industrial-grade jacket – Suited for cabinet routing and machinery skids; resists typical oil and vibration exposure.
• Consistent metrology performance – Repeatable readings help keep machinery protection setpoints trustworthy.
• Suffix-controlled options – The “-01-05” options typically define connector/jacket variations for different environments.

Technical Specifications

Application Fields

You’ll typically see the 330930-060-01-05 in machinery protection and condition monitoring loops on:

• Steam and gas turbines (radial/axial vibration and shaft position systems)
• Compressors and expanders on petrochemical trains
• Large pumps, fans, blowers, and gearboxes
• Critical electric motors where continuous monitoring is required

A maintenance lead from a refinery told us they standardize on 6 m cables like this to keep spares simple—short enough to manage in cabinets, long enough to reach across most bearing housings on skids without adding junctions.

Advantages & Value

• Reliability – Stable signal integrity reduces nuisance trips and time spent chasing intermittent faults.
• Guaranteed fit – Works within the 3300/3300 XL proximity measurement chain, which, from my experience, keeps calibration consistent.
• Lower lifecycle cost – Pre-terminated cables cut install time and limit rework caused by field-termination variability.
• Risk control – Proper shielding and grounding layout minimizes EMI susceptibility inside crowded panels.
• Support-ready – Easy for technicians to swap during shutdowns to quickly isolate probe vs. cable vs. proximitor issues.

Installation & Maintenance

• Environment – Mount in a clean cabinet or routed in cable tray/conduit; allow ventilation and avoid pooling oil/condensate.
• Routing – Keep clear of high-voltage and VFD motor leads; maintain separation to reduce EMI. Avoid tight bends; a gentle radius is typically preferred.
• Shielding/Grounding – Follow Bently Nevada grounding practice; do not create ground loops. Verify continuity on shields during commissioning.
• Connections – Seat connectors firmly into the probe and Proximitor; do not over-tighten strain reliefs. Label both ends for traceability.
• Routine checks – Inspect jacket condition each outage, clean connectors, and re-verify probe gap and bias voltage after any cable change.

Quality & Certifications

• Compliance – Typically designed to meet CE and RoHS for the proximity sensing chain; hazardous area options may depend on specific suffix configurations.
• Warranty – 365-day warranty from us. Manufacturer’s standard policies apply where applicable.
• Traceability – Supplied new, with original part number identification for audit and maintenance records.

Supporting Components (Common Mates)

• BENTLY NEVADA 3300/3300 XL Proximity Probes – The front-end sensors installed at the bearing housing; the extension cable links these to the Proximitor.
• BENTLY NEVADA 3300 XL Proximitor Sensors – Signal conditioning modules that drive the probe and output the vibration/position signal to the monitor.
• BENTLY NEVADA 3500 Series Monitors – Rack-based monitoring (e.g., radial vibration, thrust position) that receives conditioned signals for protection and trending.
