Bently Nevada 330130-045-00-05 3300 XL 8 mm Proximity Probe – Reliable shaft vibration and position measurement (4.5 m integral cable)

The 330130-045-00-05 is part of the Bently Nevada 3300 XL 8 mm proximity transducer system, used worldwide on turbines, compressors, pumps, and gearboxes. It’s the probe portion with an 8 mm tip and an integral 4.5 m cable, designed to pair with a 3300 XL extension cable and a matching 3300 XL Proximitor sensor. From my experience, this setup gives you stable, repeatable measurements for both dynamic vibration and static shaft position in demanding environments.

Key Features

• 8 mm probe tip – Suitable for standard industrial targets and clearances on mid‑to‑large rotating machinery.
• Integral 4.5 m cable – The “-045” length simplifies routing to the junction box or Proximitor via an extension cable.
• Part of the 3300 XL system – Works with matching extension cable and 3300 XL Proximitor sensor for a complete eddy‑current transducer chain.
• Non-contact measurement – Captures dynamic vibration and static shaft position without mechanical wear.
• Stable scaling – With the appropriate 3300 XL Proximitor, you get the standard 200 mV/mil (7.87 V/mm) sensitivity used in most Bently Nevada installations.
• Rugged for harsh areas – The 3300 XL series is known for temperature tolerance and mechanical robustness on high-speed machines.
• Backwards compatibility – In many cases, it’s drop-in compatible with existing 3300 XL systems in the field.

Communication Interfaces	Analog measurement chain (no digital comms at the probe)
Installation Method	Threaded mounting into probe holder or bracket; non‑contact to target; initial gap set per 3300 XL guidelines (typically ~1 mm)

Application Fields

You’ll typically see the 330130-045-00-05 used for:

• Radial vibration on steam and gas turbines, centrifugal compressors, and large motors
• Axial thrust position on turbines and multi-stage pumps (with appropriate mounting)
• Shaft runout and phase reference when paired with Keyphasor configurations
• Condition monitoring and protection systems in refineries, petrochemical plants, and power generation

Advantages & Value

• Field-proven reliability – The 3300 XL line has a strong track record in continuous-duty critical machinery.
• System compatibility – Works with existing 3300 XL extension cables and Proximitor sensors to maintain calibration and scaling.
• Lower lifecycle cost – Non-contact sensing minimizes wear; the standard sensitivity simplifies spares across assets.
• Supportable choice – Easy to integrate with common protection/monitoring racks (e.g., 3500 series) and portable analyzers via buffered outputs.

“We installed the 330130 probes on a two‑casing compressor train. Gap checks were straightforward, and the vibration trends stabilized right away. It seems to be less sensitive to temperature swings than the older probes we had.” — Maintenance Supervisor, petrochemical plant

Compatible Accessories and Related Models

• 3300 XL Extension Cables – Common lengths (for example 5 m, 7 m, 9 m) to complete the specified system length.
• 3300 XL Proximitor Sensor (5 mm/8 mm) – Provides the powered conditioning and standard 200 mV/mil scaling for vibration and gap outputs.
• Mounting Hardware – Probe holders, brackets, and sleeve adapters to achieve the correct mechanical fit and target coverage.

You might notice that the “-05” suffix is often associated with specific build/approval options. If your site requires particular agency approvals, we’ll verify the exact variant before shipping.

Installation & Maintenance

• Environment – Mount in a rigid probe holder; avoid vibration of the holder itself. Ensure good ventilation around the Proximitor housing if panel‑mounted.
• Wiring – Route the probe cable separately from high‑power lines; observe minimum bend radius; ground the shield at the Proximitor end only.
• Gap/Calibration – Set the nominal gap using the DC output from the Proximitor (commonly around −10 Vdc corresponds to ~1 mm). Verify linear range and clearance.
• Safety – De‑energize associated machinery protection circuits before changing sensors. Use correct thread engagement and locking to prevent probe movement.
• Routine checks – Periodically confirm gap voltage, inspect cable integrity, and clean the probe tip if contamination is present. No firmware updates apply to probes.

Quality & Certifications

• Manufactured under ISO 9001 quality systems
• CE marking and RoHS compliance typically available for 3300 XL family builds
• Hazardous area approvals may be available depending on exact suffix; we’ll confirm per order
