BENTLY NEVADA 330103-00-06-05-02-05 – 3300 XL 8 mm Proximity Probe for critical machinery vibration and position monitoring

The BENTLY NEVADA 330103-00-06-05-02-05 is part of the 3300 XL 8 mm proximity transducer family, widely used on turbines, compressors, and large pumps for non-contact measurement of shaft vibration, radial/axial position, and rotor-to-stator clearance. From my experience, this model is chosen when teams need a durable 8 mm probe that pairs seamlessly with a 330130 extension cable and a 3300 XL Proximitor Sensor (typically 330180) to meet API 670 practices with consistent linearity and scale factor.

Our Order Process & Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express delivery: FedEx, UPS, DHL
• Pre-shipment verification: We confirm suffix codes and compatibility (probe, cable, Proximitor) before dispatch

Key Features

• 3300 XL 8 mm sensing tip – Non-contact eddy-current probe for conductive targets, designed for heavy-duty rotating machinery.
• API 670-aligned performance – In most cases, the 3300 XL probe/cable/Proximitor chain delivers the linear range and scale factor maintenance teams expect.
• System scale factor (typical) – 7.87 mV/µm (200 mV/mil) when used with the matching 3300 XL Proximitor Sensor.
• Linear range suited to large rotors – Typically around 2 mm (80 mil) on 4140 steel, giving room for both static gap and dynamic vibration.
• Robust cabling options – Suffix codes define cable length/armoring/approvals; we verify these so you get the exact build you need.
• Electromagnetic immunity – 3300 XL design is known for reliable readings in high-noise plant environments.
• Drop-in compatibility – Fits installed bases using Bently Nevada 3300 XL systems, simplifying spares and changeouts.

Technical Specifications

Application Fields

You might notice that the 330103 often shows up on high-value rotating assets where displacement accuracy really matters:

• Steam and gas turbines – radial vibration, thrust position, and thermal growth monitoring
• Compressors and expanders – surge protection logic and bearing health trending
• Large pumps and fans – imbalance/misalignment detection and protection interlocks
• Generators and gearboxes – shaft dynamic displacement and axial shaft position
• Refinery and petrochemical machinery – API 670-compliant protection systems

Advantages & Value

• Reliability in harsh environments – The 3300 XL design is proven around oil mist, EMI, and temperature swings.
• Compatibility & lifecycle – Backward-compatible with existing Bently Nevada 3300 XL systems, saving retrofit costs.
• Procurement clarity – Suffix-defined build; we cross-check thread, cable length, and approvals before shipment.
• Maintenance efficiency – Standard scale factor and linearity simplify calibration and reduce troubleshooting time.

Installation & Maintenance

• Cabinet/driver pairing – Use with the correct 3300 XL Proximitor Sensor and 330130 extension cable; keep total system length per datasheet.
• Mounting – Rigid bracket, proper thread engagement, and jam nut torque; avoid probe bracket resonance.
• Gapping – Typically set near the mid-linear range (around 1.0 mm) on 4140 steel; verify with feeler gauge.
• Wiring – Separate probe/extension cables from high-voltage runs; maintain minimum bend radius and strain relief.
• Routine checks – Inspect cable armor/connectors, wipe tip clean during outages, and confirm DC gap stability.
• Calibration – Periodic verification against a calibrated target material; update monitoring system scaling if components are replaced.

Quality & Certifications

• Certifications: CE; hazardous area approvals (e.g., ATEX/IECEx) are suffix dependent for the complete probe/cable/driver chain.
• Manufacturing quality: Built under rigorous quality systems commonly associated with Bently Nevada’s 3300 XL line.
• Warranty: 365-day warranty coverage from shipment.

Compatible Components You May Also Need

• 330130 – 3300 XL Extension Cable (length and armor per suffix code)
• 330180 – 3300 XL Proximitor Sensor (driver) matched to the 8 mm system
• Mounting hardware – Probe brackets, jam nuts, and protective conduits as required by site standards

A maintenance lead at a combined-cycle plant told us they swapped a damaged 330103 probe during a short outage and, without changing their monitoring setup, saw immediate stabilization in axial position trending. That kind of “no-surprise” interchangeability is typically why teams stick with the 3300 XL family.
