BENTLY NEVADA 330851-02-000-030-10-00-05 – 3300 XL Proximity Probe for Shaft Vibration and Position Monitoring

The BENTLY NEVADA 330851-02-000-030-10-00-05 is a factory-configured 3300 XL proximity probe assembly designed for continuous, high-reliability displacement measurement on critical rotating machinery. From my experience, this series is commonly paired with a matching 3300 XL Proximitor Sensor and an extension cable to form a complete eddy-current proximity system used on turbines, compressors, pumps, and large motors. The option string here typically denotes build details such as the integral cable length (often 3.0 m for “-030”) and thread style, so if you’re standardizing spares, this model seems to be a good fit for many brownfield 3300 XL installations.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week when in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL
• Batch/option verification: We confirm the exact option build against your installed base before shipping to ensure drop-in compatibility.

Key Features

• 3300 XL sensing technology – Stable eddy-current displacement measurement for shaft vibration, axial position, and radial clearance in demanding environments.
• Matched system performance – When used with a 3300 XL Proximitor Sensor, you typically get a 200 mV/mil (≈7.87 mV/µm) scale factor and industry-standard linearity.
• Rugged, machine-mountable probe – Threaded probe body and locknut provide repeatable mechanical mounting on bearing housings and casing ports.
• Option-coded build – The “-030” code usually indicates a 3.0 m integral cable; other codes define thread style and connector options for straightforward replacement.
• Broad temperature capability – Probe assemblies in this family are engineered for elevated temperature zones around bearings and seals.
• Backward compatibility in many cases – Designed to integrate with existing 3300/3500 monitor channels when the probe, cable, and Proximitor are correctly matched.

Technical Specifications

Application Fields

You’ll typically see the 3300 XL probe set on:

• Steam and gas turbines – radial vibration and differential expansion measurements
• Centrifugal compressors – shaft vibration and axial thrust position
• Large motors and generators – bearing housing vibration, shaft runout
• Pumps and fans – condition monitoring in API/ISO critical services
• Gearboxes – shaft position, gear mesh diagnostics when paired with a monitor

Advantages & Value

• Reliability – 3300 XL sensors are known for long-term stability under heat and oil, which in many cases reduces unscheduled trips.
• Compatibility – Seamless use with 3300/3500 monitoring systems when probe, extension cable, and Proximitor are correctly matched.
• Cost control – Drop-in replacement cuts retrofit effort; fewer alignment hours and less instrumentation downtime.
• Technical support – We can cross-check your installed option codes and advise on probe/cable/Proximitor pairing to meet the original calibration curve.

Installation & Maintenance

• Environment – Mount the probe rigidly into a clean, dry port; avoid mechanical looseness. Keep cable routing away from high EMI sources and hot surfaces where possible.
• Wiring – Use the specified extension cable and matching 3300 XL Proximitor Sensor; maintain total system length per the option codes (probe + extension cable).
• Gap setting – Set the static gap to the recommended target (commonly around 1.0 mm, depending on rotor material and monitor setup). Verify bias voltage at the Proximitor.
• Safety – Lock out rotating equipment before installation; verify hazardous area approvals if installed in classified zones.
• Routine checks – Periodically confirm mechanical tightness, inspect cable integrity, and validate the channel with a calibrated micrometer or rotor lift. Monitor firmware updates can be applied at the rack (if using 3500 series) for improved diagnostics.

Quality & Certifications

• Conformities: CE marking; RoHS compliance. Hazardous area approvals (e.g., ATEX/IECEx) available on certain option builds.
• Manufacturing quality: Built for industrial reliability; matches 3300 XL system calibration when correctly paired.
• Warranty: 365-day warranty from shipment.

Related and Supporting Components

For a complete channel, pair the 330851-02-000-030-10-00-05 probe with:

• 3300 XL Proximitor Sensor (5 mm / 8 mm variants matched to the probe)
• 3300 XL extension cables (e.g., 330130 / 330180 series, length to match total system)
• 3500 series monitoring racks/modules for vibration, position, and Keyphasor inputs

You might notice different site inventories mixing probe and cable lengths. If your installed base uses a different option length or thread form, share the full part code on your nameplate and we’ll align the exact configuration so your scale factor and linear range remain as expected.
