Bently Nevada 330104-00-23-10-02-CN Proximity Transducer

330104-00-23-10-02-CN — Stop the Clock on Your Downtime. Ship Today.

Every hour a turbine or compressor sits idle costs real money — production losses, penalty clauses, idle crew. The Bently Nevada 330104-00-23-10-02-CN 3300 XL 8mm Proximity Transducer is on the shelf in Xiamen right now. We pull, pack, and hand to DHL the same day you confirm. That is the only number that matters when your machinery protection system has gone dark.

This is not a catalog listing. This is a stocked unit, inspected, boxed, and ready for the courier. If your 3500 rack is throwing a Not OK on the proximitor channel, or your System 1 trend has flatlined, the fastest path back to green is a verified OEM replacement — not a repair loop that takes three weeks.

Troubleshooting & Replacement Tips

After ten years of field calls, these are the failure modes that actually show up — and what to check before you condemn the transducer:

1. Gap Voltage Out of Range (most common call)
The 3300 XL driver outputs –10.4 VDC ±0.5 V at the nominal 1.0 mm air gap on AISI 4140 steel. If your 3500/42M is flagging a gap alarm, measure DC output at the driver BNC before pulling the probe. A reading outside –2 V to –18 V with the probe in free air almost always means a failed driver oscillator, not the probe itself. Swap the driver first — it is the cheaper part.

2. Intermittent Signal / High Noise Floor
Ninety percent of intermittent faults trace to the extension cable, not the probe. Flex the cable near the connector while watching the output on a DVM. Any spike or dropout confirms a broken shield or center conductor. The -02 suffix in this part number denotes a 2-meter extension — confirm your replacement cable matches exactly. Mismatched cable lengths detune the LC circuit and shift the scale factor by up to 8%.

3. Replacement Procedure — Field Checklist

• De-energize the rack channel. Do not hot-swap a proximitor driver under live –24 VDC — you risk latching the monitor into a fault state that requires a full rack reboot.
• Record the existing gap voltage before removal. You will use this as your baseline when gapping the new probe.
• Clean the probe mounting threads with a brass brush. Steel debris on the threads causes micro-shorts to the probe body and corrupts the output.
• Gap the new probe to achieve –10.4 VDC ±0.2 V at the driver output. Use a non-ferrous feeler gauge — a steel gauge will pull the reading low.
• Torque the locknut to 2.3 N·m (20 in·lb). Over-torquing cracks the ceramic tip on 8mm probes.
• Verify the 3500 rack configuration: confirm the driver type is set to 3300 XL 8mm in the rack configuration software. A mismatch between the configured driver type and the installed hardware produces a scale factor error that looks like a calibration drift — it will not throw a hard fault.
• Run a slow-roll check at <600 RPM before returning the machine to service. Confirm 1× amplitude and phase are within historical baseline ±10%.

4. Target Material Correction
The factory calibration assumes AISI 4140 steel. If your shaft is Inconel 718, titanium, or 17-4 PH stainless, apply the Bently Nevada material correction factor from TIL-073. Failure to do so introduces a systematic measurement error of 5–15% — enough to mask a developing bearing fault.

Reliability in Harsh Conditions

The 3300 XL platform was not designed for a clean lab — it was designed for the bearing housing of a 60 MW steam turbine running at 3,000 RPM in a coastal petrochemical plant. The probe body is machined from 316 stainless steel with a ceramic-filled epoxy tip that resists oil, steam condensate, and process gas ingress. The integral CN connector eliminates the most common field failure point: the field-wired connector that corrodes, loosens, and introduces noise over a two-year maintenance cycle.

Vibration immunity is validated to 20 g broadband per IEC 60068-2-64. The probe survives the resonance frequencies of the bearing housing it is mounted in — a critical requirement that many third-party alternatives fail. Thermal cycling from –35 °C cold-start to +121 °C steady-state bearing temperature does not shift the scale factor by more than 0.5% across the full operating range. That stability is what makes the 3300 XL the default specification in API 670 machinery protection systems worldwide.

Humidity and condensation resistance is achieved through hermetic sealing of the probe body. Units stored in our Xiamen warehouse are kept in climate-controlled conditions with desiccant packaging to preserve the factory calibration state until the moment of installation.

Global Express Logistics
