Bently Nevada 330103-00-09-15-05-00 | 3300 XL 8 mm Proximity Probe for Accurate Shaft Vibration and Position

The Bently Nevada 330103-00-09-15-05-00 belongs to the proven 3300 XL 8 mm proximity probe family used across turbines, compressors, pumps, and gearboxes. It’s engineered for non-contact shaft vibration and axial position measurements, and typically delivers the 200 mV/mil sensitivity that most API 670 users expect. From my experience, these probes are chosen when plants want long-term stability and easy interchangeability with existing 3300 XL hardware—without second-guessing calibration every outage.

Key Features

• 3300 XL 8 mm sensing – Non-contact eddy-current probe designed for shaft vibration and position on critical rotating assets.
• Nominal 200 mV/mil sensitivity – Pairs with the matching 3300 XL Proximitor Sensor to deliver the standard 7.87 mV/µm output many plants calibrate to.
• Stable long-term performance – The 3300 XL family is known for temperature and time stability, which typically reduces drift-related callouts.
• Robust mechanical design – Threaded body with locknuts enables secure gap setting in tight machine envelopes.
• System compatibility – Works with 3300 XL Proximitor Sensors and extension cables in 5 m, 7 m, and 9 m system lengths (depending on options).
• API 670 alignment – Commonly used in API 670-compliant monitoring architectures with Bently Nevada 3500/3701 series monitors.

Technical Specifications

Application Fields

This probe is used across oil & gas, power generation, petrochemical, steel, and paper industries—anywhere rotating machinery health is mission-critical. Typical applications include:

• Radial vibration and axial position on turbines, compressors, and high-speed pumps
• Shaft phase reference and speed (when installed as a Keyphasor target probe in suitable setups)
• Thrust bearing position trending on critical trains
• Condition monitoring inputs to Bently Nevada 3500/3701 series and compatible protection systems

Advantages & Value

• Reliability you can trend on – One thing I appreciate is how stable the 3300 XL line tends to be across seasons and shutdowns, which typically cuts re-gap and recal checks.
• Drop-in compatibility – Works with existing 3300 XL Proximitor Sensors and cabling, so replacements are straightforward and downtime stays low.
• API 670-friendly – You might notice audits go smoother when the transducer chain aligns with common API 670 practices.
• Lower lifecycle risk – Strong vendor ecosystem, readily available spares, and predictable performance reduce operational surprises.

Installation & Maintenance

• Mounting – Install through the machine casing using the specified thread (often 3/8-24 UNF or M10x1). Use locknuts and set the initial gap per the machine drawing.
• Cabinet & wiring – House Proximitor Sensors in a ventilated, dry panel. Route probe and extension cables away from high-voltage or VFD runs to minimize noise.
• Grounding – Follow the single-point grounding scheme recommended for transducer systems to avoid ground loops.
• Calibration – Verify sensitivity with a micrometer fixture during commissioning. In most cases, annual validation aligns with API 670 practices.
• Environmental care – Keep probe tips clean; avoid metallic debris on the target area. Confirm temperature ratings against the local hot-zone conditions.
• Spare strategy – Stock a like-for-like 3300 XL probe with the same option codes to maintain calibration consistency across channels.

Quality & Certifications

• Designed for use in API 670-compliant monitoring systems
• Manufacturer quality system typically certified to ISO 9001
• CE marking available on most configurations; RoHS compliance on standard builds
• Hazardous area approvals (e.g., ATEX/IECEx/CSA) may be available depending on option code—confirm before ordering
• Supplier warranty: 365 days

Compatibility note: The 330103-00-09-15-05-00 probe is intended to be used with a matching 3300 XL 8 mm extension cable and 3300 XL Proximitor Sensor to achieve the correct system length and calibration. If you’re replacing an existing probe, matching the full option string typically preserves channel scaling and linear range without reconfiguration.
