Bently Nevada 330104-00-13-10-02-05 – 3300 XL 8 mm Proximity Probe for Reliable Shaft Vibration & Position Monitoring

The Bently Nevada 330104 is part of the 3300 XL 8 mm proximity probe system that plants rely on for non-contact measurement of shaft vibration, radial position, and thrust (axial) position. From my experience, this series is the default choice when you want stable readings across outages and thermal cycles. You might notice that it pairs seamlessly with the 3300 XL Proximitor sensor and the 330130 extension cable, giving you the familiar 200 mV/mil output the major API 670 monitors are tuned for.

Key Features

• 8 mm probe tip for industrial targets – Robust tip geometry for reliable tracking on standard steel shafts and rotors.
• Non-contact eddy-current measurement – Stable displacement readings without mechanical wear; ideal for high-speed shafts.
• Standard 200 mV/mil sensitivity – Works with most Bently Nevada monitors and third‑party API 670 systems that expect 7.87 mV/µm.
• 3300 XL system compatibility – Designed to be used with the matching 3300 XL 8 mm Proximitor sensor and 330130 extension cable for calibrated system length.
• High-temperature probe/cable rating – Typically withstands up to 177 °C at the probe, which in many cases avoids special high-temp variants.
• Shielded, factory‑terminated connections – Reduces electrical noise pickup and improves long-term stability.
• Flexible configuration – Option codes define cable length, thread type, and approvals; this “-00” build is generally without hazardous area approvals.

Technical Specifications

Application Fields

Typically deployed on turbines, compressors, large pumps, gearboxes, and generators where continuous shaft vibration and position trending is mandatory. We see it a lot in power generation, refining and petrochemicals, natural gas transmission, pulp & paper, and steel mills. One thing I appreciate is how predictable the readings are when installed on standard AISI 4140 targets with proper surface finish.

Advantages & Value

• Reliability under heat and vibration – The probe and cable rating up to 177 °C typically covers most bearing housings and turbine casings.
• Drop‑in compatibility – 200 mV/mil scaling avoids re-engineering your monitor cards and alarm thresholds.
• Lower lifecycle risk – Proven 3300 XL architecture and widely available spares reduce unplanned downtime.
• Procurement-friendly – Option codes let you match existing lengths/threads; we can cross-check to your tag list to avoid mismatches.
• Technical support – Assistance with gap setup, target material considerations, and cable routing to keep noise low.

Installation & Maintenance

• Mounting: Install the probe perpendicular to the shaft with the specified thread (per option code). Use the locknut and torque per the manual.
• Initial gap: Set a typical initial gap near 1.0 mm (≈40 mils), then fine‑tune with the Proximitor output to hit the recommended bias voltage.
• Cable routing: Keep probe/extension cables separated from VFD/motor power cables; avoid tight bends and protect from abrasion.
• Enclosure: Locate the Proximitor sensor in a ventilated junction box; in most cases, a clean, dry, IP54 or better cabinet is sufficient.
• Grounding: Bond shields at the monitor end; follow single‑point grounding to minimize ground loops.
• Routine checks: Verify gap and bias annually, inspect connectors for corrosion, and wipe probe tips during outages if accessible.
• Calibration: When replacing components, keep system length consistent (probe + extension cable) to maintain factory calibration.

Quality & Certifications

• Manufacturer quality systems in line with ISO practices; CE compliant
• RoHS compliance for most variants; hazardous area approvals available on alternate option codes
• Meets the intent of API 670 proximity transducer requirements when used as a complete 3300 XL system
• Warranty: 365 days from delivery

Field note: a petrochemical compressor train we supported swapped in 330104 probes during a hot section overhaul and reported more stable bias voltage on restart, which seems to be tied to cleaner cable routing and correct system length (probe + 330130 + 3300 XL Proximitor). If you want, we can help validate your option code “-00-13-10-02-05” against installed base drawings before you place the order.
