Bently Nevada 330171-00-12-10-01-05 – Proximity Probe Assembly for 3300 XL Vibration and Shaft Position Monitoring

The 330171-00-12-10-01-05 is part of the Bently Nevada 3300 XL proximity sensing lineup, typically used for non-contact measurement of shaft vibration, axial position, and rotor speed on critical rotating assets. From my experience, this model format indicates a probe assembly with defined cable length and mechanical options, designed to pair with a matching 3300 XL Proximitor sensor and extension cable. If you’re standardizing on API 670-style condition monitoring, this is a familiar, field-proven choice that integrates smoothly with existing Bently Nevada systems.

Key Features

• Non-contact eddy-current measurement – Captures shaft vibration/position without mechanical wear.
• 3300 XL ecosystem compatibility – Pairs with 3300 XL Proximitor sensors and extension cables for a calibrated chain.
• Standard system sensitivity – Typically 200 mV/mil (≈7.87 mV/µm) with the correct Proximitor, simplifying cross-plant setup.
• Industrial-grade materials – Rugged probe body and cable armor options to handle oil mist, high temperature, and tight routing.
• API 670-style performance – Suited to turbomachinery monitoring where repeatability and stability matter.
• Flexible mounting options – Threaded insertion into machine casings or brackets; orientation-friendly for limited clearances.

Technical Specifications

The entries below reflect typical characteristics for the 3300 XL-style probe assembly family. Specifics can vary based on option codes in 330171-00-12-10-01-05.

Application Fields

• Compressors and gas turbines – Shaft vibration and thrust position monitoring tied to trip logic.
• Pumps and fans – Bearing housing vibration and rotor dynamic behavior trend analysis.
• Generators and motors – Air-gap/position checks and long-term balancing programs.
• Refining, petrochemical, and power plants – API 670-style protection and predictive maintenance.
• Paper, steel, and cement mills – Harsh environments where armored cabling and stable calibration matter.

One thing I appreciate is how consistently the 3300 XL chain holds calibration across outages. A maintenance lead at a combined-cycle site put it simply: “We swapped the probe and re-gapped; trend lined up with our historical baseline within minutes.”

Advantages & Value

• Reliability – Proven stability in high-temperature, oil-laden enclosures and tight routing paths.
• Compatibility – Works with existing Bently Nevada 3300 XL Proximitor sensors and monitoring racks, cutting retrofit risk.
• Lower lifecycle cost – Durable probe tips and armor options help reduce unplanned shutdowns and repeated rewiring.
• Traceable calibration – Standardized sensitivity simplifies multi-unit deployments and documentation.
• Support and spares – Easy to stock alongside common companions like 330130 extension cables.

Installation & Maintenance

• Panel/Cabinet – Mount the Proximitor in a ventilated cabinet; follow earthing/shielding practices to minimize noise coupling.
• Routing – Maintain minimum bend radius for armored cables; avoid parallel runs with high-voltage lines where possible.
• Gapping – Set the probe gap per datasheet using a feeler gauge; verify bias voltage at the Proximitor output.
• Safety – Lock-out/tag-out rotating equipment; confirm hazardous area approvals match the zone classification.
• Routine Care – Periodically check gap, cable integrity, and connectors; clean probe tips carefully to avoid metal swarf buildup.
• Firmware/Monitoring – When connected to condition monitoring systems, keep monitor firmware current and back up alarm settings.

Quality & Certifications

• CE-marked and RoHS compliance in many configurations; hazardous area approvals (e.g., ATEX/IECEx/CSA) are option-dependent.
• Manufacturer’s warranty: 12 months from delivery (365 days).
• Production and test traceability typically available for quality audits.

Compatible/Supporting Components (commonly paired)

• Bently Nevada 3300 XL Proximitor Sensor (5 mm or 8 mm variants, depending on probe type)
• Bently Nevada 330130-xx-xx-xx Extension Cable (length and armor per site standard)
• Monitoring systems: Bently Nevada 3300/3500 series or compatible condition monitoring hardware
