Bently Nevada 330910-00-13-05-02-00 Proximity Probe

330910-00-13-05-02-00 — Stop the Clock on Your Downtime. Ship Today.

Every hour your turbine, compressor, or pump sits idle because of a failed proximity probe is money bleeding out of your operation. The Bently Nevada 330910-00-13-05-02-00 — a 3300 XL Series 8mm eddy-current proximity probe with 5m integral cable — is one of the most common single points of failure in rotating machinery protection systems. We stock it. We ship it fast. From Xiamen to your site, DHL or FedEx, door to door.

This is not a listing page. This is a field-ready resource. If you are reading this at 2 AM because your DCS just threw a Probe Not OK alarm and your maintenance window closes in six hours, you are in the right place.

Troubleshooting & Replacement Tips

The 330910-00-13-05-02-00 fails in predictable ways. Here is what ten years of field calls have taught us:

Fault Code: Probe Not OK (PNO) / -24V Supply Loss
Ninety percent of PNO alarms trace back to three causes: cable jacket damage from vibration fatigue at the conduit entry point, connector corrosion at the Proximitor junction, or a cracked probe tip from a rub event. Before condemning the probe, check the Proximitor output voltage. If it reads outside −10 VDC to −18 VDC at the nominal gap, the probe-cable system is suspect. Swap the probe first — it is the cheapest component in the transducer chain.

Gap Setting After Replacement
The recommended initial gap for the 330910 is 1.27 mm (50 mil). Use a non-ferrous feeler gauge or a calibrated gap meter. Do not rely on the old probe’s locknut position — thermal cycling shifts the housing. Verify the Proximitor output reads approximately −10.4 VDC at the set gap before tightening the locknut. Torque the locknut to the manufacturer spec; over-torquing cracks the probe body on the 8mm series.

Driver Matching — Do Not Mix Systems
The 330910 is calibrated as a matched system with the 330180 Proximitor Sensor. If you are replacing only the probe and reusing the existing extension cable, verify the total cable length (probe integral + extension) matches the Proximitor’s configured range. A 5m probe paired with a 5m extension cable gives a 10m system — confirm your Proximitor is set for 10m, not 5m. Mismatched cable length shifts the sensitivity curve and will cause false vibration readings.

Target Material Correction
The factory calibration assumes AISI 4140 steel shaft material. If your shaft is 17-4PH stainless, Inconel, or titanium, a target material correction factor must be applied at the monitor level. Skipping this step introduces a systematic measurement error of up to 15% — enough to mask a real vibration event or trigger nuisance trips.

Firmware / Monitor Compatibility
If you are installing into a 3500 Series rack, confirm the monitor card firmware supports the 3300 XL transducer type. Older 3500/40M cards on firmware below Rev. 3.x may require a configuration download after probe replacement to re-validate the channel. Use System 1 or the 3500 Rack Configuration Utility to push the updated config before returning the machine to service.

Common Fault Codes to Know

• OK Relay De-energized: Check supply voltage at Proximitor — should be −24 VDC ±10%.
• High Vibration Trip (spurious): Inspect cable routing for contact with rotating parts or high-frequency EMI sources.
• Keyphasor Signal Lost: If this probe is used as a phase reference, verify the notch/key geometry and re-set the gap to the tighter end of the linear range (0.5 mm) for a cleaner pulse edge.
• Eccentricity Alarm on Startup: Normal on cold start if the shaft has a bow. Monitor slow-roll data for 15 minutes before alarming the channel.

Reliability in Harsh Conditions

The 3300 XL 8mm probe is not a lab instrument. It was designed for the inside of a turbine bearing housing — 177°C continuous, oil mist, high-frequency vibration, and the occasional water ingress event. The stainless-steel probe body and PTFE-jacketed integral cable handle thermal cycling without the connector loosening that plagues cheaper alternatives.

In petrochemical and LNG applications, we have seen these probes run continuously for 8–12 years between planned replacements. The failure mode, when it comes, is almost always the cable — not the probe tip. The eddy-current coil itself is encapsulated in a ceramic-filled epoxy that resists both chemical attack and mechanical shock from rub events up to a certain severity.

For offshore and high-humidity environments, the ATEX/IECEx certified variants (suffix -AT or -EX) add an additional layer of ingress protection. If your installation is in a Zone 1 or Zone 2 classified area, confirm the certification suffix on your part number before ordering. The standard 330910-00-13-05-02-00 is not rated for classified hazardous areas without the appropriate certification variant.

Vibration endurance: the probe assembly is rated to withstand 20g sinusoidal vibration across 10–2,000 Hz per IEC 60068-2-6. In practice, installations on high-speed compressors running at 12,000+ RPM with significant casing vibration have shown no degradation in probe performance over multi-year intervals, provided the cable is properly clamped at 300mm intervals to prevent resonant fatigue.
