BENTLY NEVADA 330105-02-12-05-02-00 – 3300 XL Proximity Probe for Critical Machinery Monitoring

The BENTLY NEVADA 330105-02-12-05-02-00 is a 3300 XL proximity probe used for non-contact shaft vibration and position measurement on rotating assets. It’s designed to work as part of a three‑component system (probe + extension cable + Proximitor sensor), giving you a stable, linear displacement signal that plays nicely with API 670-type protection and condition monitoring strategies. From my experience, this model is often chosen when plants want drop‑in compatibility with existing 3300 XL installations and predictable, repeatable results across shutdowns and turnarounds.

Key Features

• 3300 XL family compatibility – Pairs with 3300 XL Proximitor sensors and standard extension cables for a calibrated, linear output.
• Non-contact eddy-current measurement – Measures shaft vibration, radial position, or thrust movement without mechanical wear.
• Stable, repeatable performance – The 3300 XL design typically delivers excellent linearity and temperature stability in harsh environments.
• Build-code driven configuration – This build appears to include a 12 ft integral cable (-12) and a common UNF mounting thread (-05), suitable for standard probe holders.
• Harsh-duty construction – Rugged probe and cable construction for compressors, turbines, and other critical duty applications.
• API-friendly scaling – When used with a matched Proximitor, the system provides the standard 200 mV/mil (≈7.87 mV/µm) output most plants expect.

Technical Specifications

Application Fields

You’ll typically see this probe on steam and gas turbines, centrifugal and reciprocating compressors, high‑speed pumps, gearboxes, and generators. It’s used for radial vibration, shaft position/runout, and thrust position measurements in protection systems and for trending in condition monitoring software. One thing I appreciate is how easily it fits into existing 3300 XL loops during turnarounds—maintenance teams usually don’t have to relearn anything.

Advantages & Value

• Reliability in harsh service – The 3300 XL platform is proven on high-temperature, high-vibration machines.
• Compatibility – Works with standard 3300 XL Proximitor sensors and extension cables, minimizing spares complexity.
• Lower lifecycle cost – Fewer nuisance trips and stable calibration typically reduce downtime and troubleshooting hours.
• Supportable architecture – Easy to document and maintain; technicians are usually familiar with the 3300 XL hardware chain.

Installation & Maintenance

• Mounting – Install in a rigid probe bracket or sleeve; set the gap to mid‑range per your Proximitor (often near 1.0 mm). The “-05” build commonly corresponds to a UNF mounting thread, which suits standard holders.
• Cable routing – Keep coax away from high‑power cables; avoid tight bend radii; use protective conduit in high‑traffic areas.
• Environment – Enclose the Proximitor in a ventilated cabinet to IEC/NEMA standards; the probe and cable tolerate higher temperatures than the electronics in most cases.
• Checks and calibration – Verify gap voltage and linear response after installation; confirm the system length (5 m or 9 m) matches your probe/extension combination.
• Routine maintenance – Wipe the probe tip during outages, inspect cable integrity, and document bias/gap readings; firmware updates only apply to connected monitors, not the probe itself.
• Safety – Lock out the machine, use non‑magnetic tools near the shaft, and follow plant hazardous‑area procedures where applicable.

Quality & Certifications

• Typically CE marked and RoHS compliant; produced under ISO 9001 quality systems.
• Hazardous‑area approvals may be available depending on build; confirm against your site requirements.
• Manufacturer’s warranty practices align with industrial duty expectations; our supply warranty is 365 days as stated above.
