Bently Nevada 330104-00-16-10-02-05 – 3300 XL 8 mm Proximity Probe for Critical Machinery Vibration and Position Monitoring

The Bently Nevada 330104-00-16-10-02-05 is part of the 3300 XL 8 mm proximity probe family widely used on turbines, compressors, large motors, and gearboxes. From my experience, it’s the go-to choice when you need stable gap measurements in harsh, high-temperature environments and full compatibility with 3300/3500 monitoring systems.
This build code appears to denote an 8 mm probe with an integral cable (typically 16 ft per the “-16-” position code), and a threaded mounting option under “-10-” (commonly a 3/8-24 UNF mount in many cases). It mates with the 3300 XL Proximitor Sensor and the 330130 extension cable to deliver the standard 200 mV/mil (7.87 mV/µm) displacement signal.

Key Features

• True 8 mm sensing tip: Designed for larger gap targets and rugged machinery, with excellent linearity in the standard range.
• Standard Bently Nevada scale factor: 200 mV/mil (≈7.87 mV/µm) when used with the matching 3300 XL Proximitor—makes data consistent across assets.
• High temperature capability: Probe construction typically supports up to 177°C at the tip, ideal for hot bearing housings.
• Full system compatibility: Works with 330130 extension cables and 3300 XL Proximitor Sensors; drops into 3300/3500 monitoring racks.
• Robust mechanical design: Stainless steel body and molded tip material for long service life in oily, dirty conditions.
• Option-coded build: “-16-” commonly denotes a 16 ft integral cable; “-10-” is a common threaded mount option (often 3/8-24 UNF).

Technical Specifications

Application Fields

This probe is typically deployed on:

• Steam and gas turbines (radial vibration, shaft position/gap)
• Large compressors and expanders (bearing vibration, thrust position when paired appropriately)
• Critical pumps and fans in petrochemical plants
• Generators and high-voltage motors (bearing and shaft dynamics)

One maintenance lead told me they swapped a mixed set of older probes for 3300 XL units and immediately saw steadier baseline readings—less drift during hot restarts, which usually means fewer nuisance alarms.

Advantages & Value

• Reliability under heat and oil: The 8 mm XL build holds calibration well in dirty, high-temperature zones.
• Drop-in system fit: Seamless with Bently Nevada 3300/3500 racks—no re-engineering of scale factors or cabling.
• Lifecycle savings: Fewer re-gaps and reduced false alarms can cut maintenance callouts over time.
• Configuration flexibility: Multiple thread and cable options; your “-16-” cable length usually simplifies routing in tight panels.
• Support ecosystem: Abundant spares and documentation; easy to standardize across assets.

Installation & Maintenance

• Environment: Mount on a rigid, clean, grounded machine surface. Use standard industrial enclosures for the Proximitor with adequate ventilation (per panel standards).
• Wiring: Keep probe/extension cables away from high-voltage runs; maintain minimum bend radius and avoid cable strain. Use matched 330130/Proximitor pairs for accuracy.
• Gap setting: Set the mechanical gap to the target (often around 1.0 mm for 8 mm systems), then verify with the Proximitor bias voltage.
• Safety: De-energize the monitor loop during installation; confirm hazardous-area approvals match the site classification if applicable.
• Routine care: Inspect cable armor/boot (if fitted), clean the probe tip during shutdowns, and verify readings after thermal cycles or bearing work. Firmware updates apply at the monitor level, not the probe.
• Calibration checks: In most cases, a quick bias and linearity check against a known target is sufficient after rework or replacement.

Quality & Certifications

• Conformity: CE compliant; ATEX/IECEx/CSA hazardous approvals are option-dependent (the “00” in this code typically indicates a standard approval set).
• Materials & build: Industrial-grade stainless steel body and high-temperature tip materials for long service life.
• Warranty: Supply warranty 365 days from delivery.

Recommended Supporting Components

• Bently Nevada 330130-XXXXX: 3300 XL extension cable (match length to your route; keep probe/cable/Proximitor as a calibrated set).
• Bently Nevada 3300 XL Proximitor Sensor (e.g., 330180 series): Provides excitation and the conditioned displacement output.
• Bently Nevada 3500/3701 monitoring modules: For radial vibration, axial position, and alarms/trips integration.
