Bently Nevada 330103-00-09-10-02-05 – 8 mm Proximity Probe for Shaft Vibration and Position Monitoring

The Bently Nevada 330103-00-09-10-02-05 is part of the 3300 XL 8 mm proximity probe system that plants rely on for critical machine protection. From my experience, this probe is typically paired with the 330130 extension cable and the 330180 8 mm Proximitor sensor to deliver stable, API 670–class measurements of shaft vibration, radial position, and thrust. You might notice that it holds calibration well over time, which is why maintenance teams keep it as a standard across compressors, turbines, and large motors.

Key Features

• 8 mm 3300 XL proximity probe – Non-contact eddy-current sensing for continuous vibration and position measurement on metallic targets.
• Build code specificity – “-09” probe length option, “-10” system length (typically 10 ft), “-02” ClickLoc-style coaxial connectors, and “-05” agency-approved build.
• Stable system sensitivity – With the matching 330180 Proximitor, the system typically provides 7.87 mV/µm (200 mV/mil), helping you trend reliably over long campaigns.
• Wide temperature capability – Designed for hot rotating machinery; the probe typically supports -51 to +177 °C applications (extension cable limits may apply).
• API 670–style performance – In many cases used on API-class equipment for protection, balancing, and diagnostics.
• Rugged field hardware – ClickLoc connectors reduce accidental loosening, and the cable construction resists oil and mechanical abuse common in industrial environments.
• Drop-in compatibility – Works with established Bently Nevada 3300 XL systems, simplifying spares management and change control.

Technical Specifications

Application Fields

This model is widely used on high-value rotating assets where shutdown protection matters:

• Steam and gas turbines – radial vibration, eccentricity, and slow-roll checks
• Compressors and expanders – shaft vibration and axial/thrust position (with appropriate probe orientation)
• Large motors, generators, and fans – continuous protection and trending
• Gearboxes and pumps – bearing and shaft condition monitoring under variable loads

A maintenance supervisor told us it “seems to be the least fussy of all our probes—set it once and we don’t have to chase drift,” which lines up with what we typically see in long-cycle service.

Advantages & Value

• Reliability – Proven 3300 XL design with robust connectors for fewer nuisance faults.
• Compatibility – Works seamlessly with 330130 extension cables and 330180 Proximitor sensors already installed on many racks.
• Lifecycle cost – Stable calibration and interchangeable spares typically mean less time reworking configuration and alignments.
• Technical support – Clear build codes simplify cross-referencing, and we can help validate the system length and approvals against your site standards.

Installation & Maintenance

• Mounting – Install the probe in a rigid holder with the supplied jam nut; target material should be ferromagnetic (e.g., 4140 steel). Set nominal gap per the Proximitor datasheet (commonly around 1.0 mm for 8 mm systems).
• Cable routing – Use the specified 330130 extension cable; avoid tight bends, hot spots, and high-EMI paths near VFDs. Secure at regular intervals to prevent fretting.
• Cabinet environment – Mount the 330180 Proximitor in a ventilated enclosure; in most cases, a standard industrial cabinet with good grounding and shield terminations works best.
• Safety – De-energize associated monitoring circuits during installation. For hazardous areas, verify the “-05” approvals align with the site classification before commissioning.
• Routine care – Periodically verify gap and runout during outages, check connector tightness (ClickLoc), clean oil residue from the probe face, and keep firmware on the monitoring rack up to date.

Quality & Certifications

• Manufacturer compliance typically includes CE; hazardous area approvals are indicated by the “-05” build (ATEX/IECEx/CSA as applicable to region and part label).
• Produced under established quality systems (commonly ISO-based at the manufacturer’s facilities).
• Our supply warranty: 365 days.

Compatible Components & Typical System Build

• Extension Cable: Bently Nevada 330130 (length to suit system length code “10”)
• Proximitor Sensor: Bently Nevada 330180 (8 mm), providing DC gap and AC vibration outputs
• Monitoring Racks / Modules: Typically 3500 series or compatible monitors for protection and trending

If you’re standardizing spares, this exact build (330103-00-09-10-02-05) is a safe pick when you need a 10 ft 8 mm probe system with ClickLoc connectors and agency-approved labeling. If your installed base mixes system lengths, I’m happy to double-check the -xx codes against your machine tags before you place the order.
