Bently Nevada 330905-00-06-10-02-00 Proximity Probe

330905-00-06-10-02-00 — Stop the Clock on Your Downtime. Ship Today.

Your turbine is down. The 3300 XL rack is throwing a Not OK alarm. Maintenance is standing by. Every hour offline is burning through your production budget — and the clock doesn’t care about lead times. The Bently Nevada 330905-00-06-10-02-00 is in stock at our Xiamen warehouse right now. We’ve shipped this exact part number to compressor stations, power plants, and refineries across four continents. We know what’s at stake, and we move fast.

This is an 8mm eddy-current proximity probe from the Bently Nevada 3300 XL Proximity Transducer System — the most widely deployed continuous shaft-monitoring platform in rotating machinery protection. Configuration: 6-inch armored integral cable, 10-32 UNF connector, standard sensitivity (200 mV/mil). It is a direct, drop-in replacement for the OEM-installed unit. No rack recalibration. No firmware update. Bolt it in, verify gap voltage, and restart.

Troubleshooting & Replacement Tips

Symptom: Monitor channel shows Not OK or gap voltage out of range (typical OK window: –10 to –18 VDC)

Before condemning the probe, work through the loop systematically. A bad reading can originate at the probe, the extension cable junction, or the Proximitor itself. Disconnect the extension cable at the probe end and measure the Proximitor output voltage with a calibrated meter. If the voltage is still out of range with the probe disconnected, the Proximitor is suspect — not the probe. If voltage normalizes, the fault is in the probe or cable.

Replacement procedure — field-verified steps:

1. De-energize the monitor channel. Do not power down the entire rack if other channels are protecting live machinery.
2. Record the existing probe gap setting — measure gap voltage before removal and note the physical gap distance (typically 50 mil / 1.27 mm for 8mm probes on steel targets).
3. Remove the lock nut and back the probe out of the holder. Disconnect at the extension cable junction first to avoid cable twist damage.
4. Thread the new 330905-00-06-10-02-00 into the holder. Set gap to the recorded distance. Verify gap voltage: should read approximately –10.4 VDC at 50 mil on AISI 4140 steel. Adjust in 5 mil increments until within spec.
5. Torque the lock nut to bracket specification (typically 20–25 in-lb). Re-energize the channel and confirm OK status on the monitor.
6. Log the replacement in your maintenance record with the new probe serial number and gap voltage at commissioning.

Common fault codes on 3500 Series monitors when this probe fails:

• OK Relay drops out: Gap voltage outside –10 to –18 VDC window — probe gap drift or probe failure.
• High vibration alarm with no process change: Probe tip contamination (oil sludge, metallic debris) causing false eddy-current signal — clean target area and re-gap.
• Intermittent Not OK: Loose 10-32 UNF connector at the probe-to-extension cable junction — retorque to 12 in-lb.
• Flat signal / zero vibration reading: Open circuit in armored cable — flex the cable near the probe body while monitoring output; replace if signal drops.

Configuration note: The 330905-00-06-10-02-00 uses standard sensitivity. If your Proximitor is configured for extended range or a non-standard target material (titanium, aluminum), the scale factor in the monitor rack must be adjusted accordingly. Verify the Proximitor output curve against the 3300 XL calibration data sheet before finalizing the gap setting.

Reliability in Harsh Conditions

The 3300 XL 8mm probe was designed for continuous, unattended operation in the worst environments rotating machinery can produce. The armored integral cable on the 330905-00-06-10-02-00 withstands the mechanical abuse of bearing housing installations: constant low-frequency structural vibration, thermal cycling between cold startups and full-load operating temperatures, and exposure to process fluids including lube oil, seal gas condensate, and steam.

The probe body tolerates sustained temperatures up to 177°C — sufficient for most steam turbine bearing housing applications without additional thermal isolation. In environments exceeding this threshold (hot gas expanders, high-pressure steam extraction points), specify a probe extension cable with thermal break. The eddy-current sensing element has no moving parts, no contact wear mechanism, and no consumable components. Mean time between failures in clean installations routinely exceeds 10 years of continuous operation.

Vibration immunity is inherent to the non-contact measurement principle: the probe does not touch the shaft, so there is no mechanical coupling path for vibration to degrade the sensor. The armored cable is secured with cable clamps at 150mm intervals per API 670 installation practice to prevent resonant cable vibration from inducing false signals. In offshore and marine installations subject to ship motion and wave-induced structural vibration, this clamping discipline is critical — a loose cable can generate broadband noise that masks real shaft vibration events.
