330103-11-19-10-02-00 — Stop the Clock on Your Downtime. Ship Today from Xiamen.

Every hour a critical rotating machine sits idle costs real money — compressor trains, steam turbines, pumps. When your 3300 XL proximity transducer system throws a fault or a probe fails physical inspection, you don’t have days to wait on a distributor’s lead time. We stock the Bently Nevada 330103-11-19-10-02-00 8 mm eddy-current proximity probe and we move fast. Order confirmed before cut-off, DHL label printed same day.

Troubleshooting & Replacement Tips

Field experience with the 3300 XL system surfaces the same failure patterns repeatedly. Here is what to check before you pull the trigger on a replacement and what to watch during installation.

Common Fault Indicators

• OK LED extinguished on the Proximitor / monitor card: First suspect is gap voltage out of range. Measure DC output at the Proximitor output terminal — should read between −10 V and −12 V at nominal 1.0 mm gap. If you are reading −24 V (rail) or 0 V, the probe or extension cable has an open circuit. Swap the probe first — it is the most field-exposed component.
• High vibration alarm with no process change: Check probe tip for mechanical contact marks or contamination. Conductive debris on the probe face shifts the apparent gap and generates false vibration signals. Clean with isopropyl alcohol; if pitting is visible, replace.
• Intermittent signal / noisy waveform on the monitor: Inspect the armored cable at the probe body junction — this is the highest-stress point. Flex fatigue cracks here are invisible externally. Substitute a known-good probe to isolate.
• 3500 monitor showing Not OK after probe swap: Verify the replacement probe integral cable length matches the original. The 3300 XL system is tuned for specific cable length plus extension cable combinations. The 330103-11-19-10-02-00 designator encodes a 1.0 m integral cable — confirm your extension cable (330130 series) length is unchanged.

Replacement Procedure — Key Steps

• De-energize the monitor channel before disconnecting the probe. The Proximitor driver circuit is sensitive; hot-swapping under live −24 VDC can damage the oscillator stage.
• Record the existing gap voltage before removal. Use this as your target during reinstallation — saves time on re-gapping.
• Thread the new probe to the same depth as the original. Use the locknut and jam nut; torque to manufacturer spec — do not over-torque, the probe body is stainless but the bracket is often softer material.
• After installation, verify gap voltage at the Proximitor output terminal before re-energizing the monitor. Target: −10.0 V to −12.0 V for a 1.0 mm gap on a steel target.
• Perform a static calibration check if the machine is still offline — compare output voltage vs. measured gap at 3 to 4 points across the linear range.
• No firmware or DIP switch configuration is required for this probe — it is a passive transducer. All system configuration resides in the Proximitor sensor and the 3500 monitor card.

Reliability in Harsh Conditions

The 330103-11-19-10-02-00 is built for environments that destroy lesser sensors. The probe body is machined from 316 stainless steel — resistant to the process fluids, lubricating oils, and cleaning solvents common in turbomachinery bearing housings. The armored cable jacket handles continuous flexing and protects the coaxial signal conductor from EMI generated by adjacent VFDs and motor starters.

Vibration endurance is not a concern for a non-contact probe — there are no moving parts. The eddy-current coil is encapsulated in a thermally stable compound rated to +177 °C at the probe tip, which covers the bearing housing temperatures seen on gas turbines and high-speed compressors running at elevated ambient conditions. In humid tropical or coastal installations, the sealed construction prevents moisture ingress that would otherwise detune the coil and shift sensitivity.

Units in our Xiamen stock are stored in climate-controlled conditions, individually packaged in anti-static foam, and inspected before dispatch. We do not ship shelf-worn inventory.
