Bently Nevada 330173-00-02-10-02-CN Proximity Probe

330173-00-02-10-02-CN: Stop the Clock on Your Downtime — Ship Today from Xiamen

Every hour a critical turbine or compressor sits idle costs real money. When your Bently Nevada 3300 XL proximity transducer system throws a fault and the shaft position channel goes dark, you don’t have time for a 6-week OEM lead time. The Bently Nevada 330173-00-02-10-02-CN eddy-current proximity probe is on our shelf in Xiamen right now. We cut the paperwork, pull the unit, and hand it to DHL the same afternoon you confirm the order. That’s the only promise that matters when your plant manager is standing behind you.

This is a genuine, 100% original Bently Nevada 3300 XL Series probe — not a clone, not a refurb. It drops straight into your existing 330130-series extension cable and 3300 XL Proximitor without any re-ranging or recalibration. If your system was running before the probe failed, it will run again the moment this one is installed.

Troubleshooting & Replacement Tips

After ten years of field work on rotating machinery, here are the failure modes I see most often with 3300 XL proximity probes and what to watch for when you swap this unit in:

1. Gap Voltage Out of Range
The 3300 XL system expects a gap voltage between -10 VDC and -18 VDC at the Proximitor output for a properly gapped probe. If you’re reading -24 V or -4 V after installation, the probe tip-to-shaft gap is wrong — not the probe itself. Target gap for the 330173 is 1.0 mm (40 mil), which should give you approximately -10.4 VDC. Set it with a feeler gauge before you torque the locknut. Do not rely on the monitor alarm to tell you the gap is wrong; it will often mask the fault as a Not-OK without a clear gap fault code.

2. Intermittent OK/Not-OK Cycling
Nine times out of ten this is a connector issue at the extension cable junction, not a failed probe. Before condemning the 330173, disconnect and inspect the coaxial connector at the probe-to-extension interface. Moisture ingress and fretting corrosion at this joint are the primary culprits in wet or steam-laden environments. Clean with contact cleaner, re-torque to spec, and re-check gap voltage. If the cycling stops, you saved yourself a probe replacement.

3. High Noise Floor / Erratic Vibration Reading
If the 1X or 2X vibration amplitude is jumping erratically with the machine at steady state, check the extension cable routing first. The 330130 extension cable is a matched-impedance coaxial system — any sharp bend radius under 50 mm, contact with grounded conduit, or proximity to high-voltage cabling will inject noise. Re-route before replacing the probe.

4. Replacement Field Checklist

• De-energize the Proximitor driver before disconnecting the probe. Hot-swapping will not damage the monitor but it will generate spurious alarms and may trip a protection relay.
• Record the existing gap voltage before removal. This gives you a baseline for re-gapping the new probe.
• Apply a thin film of anti-seize to the 10-32 UNF threads. Stainless probe bodies gall easily in aluminum bearing housings.
• Re-gap to 1.0 mm (40 mil) and verify gap voltage at the Proximitor test point before re-energizing the monitor channel.
• Allow 15 minutes of thermal soak at operating temperature before accepting the vibration baseline — the eddy-current field is temperature-sensitive and the reading will drift slightly as the probe warms up.
• No firmware update or address switch setting is required for the 330173 — it is a passive transducer. All configuration lives in the Proximitor and the 3500 monitor rack, not in the probe.

Reliability in Harsh Conditions

The 330173-00-02-10-02-CN is built for the environments where most sensors give up. The probe body is machined from 316 stainless steel with a PEEK tip housing — it handles the combination of high-temperature steam, hydrocarbon mist, and mechanical vibration that destroys lesser sensors within months. Bently Nevada qualifies the 3300 XL probe series to 5 g continuous vibration and 50 g shock per IEC 60068-2-6 and IEC 60068-2-27. The integral cable uses a PTFE-insulated coaxial core inside a stainless braid — it won’t crack at -35 °C in an outdoor compressor station and it won’t soften at +177 °C in a steam turbine bearing pedestal.

The CN-type connector is sealed to IP67 when mated. In practice, probes from this series pulled from offshore platform bearing housings after five years of continuous service in salt-laden air show connector internals in near-new condition. That’s what a properly specified industrial connector does in a properly maintained installation.
