Bently Nevada 330103-00-06-05-02-00 Proximity Probe

330103-00-06-05-02-00 — Stop the Clock on Your Downtime: 3300 XL Probe Ships Today

Every hour a turbine or compressor sits idle costs real money — production losses, penalty clauses, idle crews. The Bently Nevada 330103-00-06-05-02-00 is a 3300 XL Series 8 mm eddy-current proximity probe with a 6 ft integral cable and 5 m extension. We stock it in Xiamen. You order it now, it moves today. No factory lead time. No eight-week wait. Just a calibrated, original probe on its way to your plant.

This is not a catalogue listing. This is a field-ready unit that has been inspected, documented, and staged for express dispatch to any industrial site on the planet.

Troubleshooting & Replacement Tips

Symptom: High vibration alarm with no change in process conditions
Before condemning the machine, check the probe gap voltage at the driver terminal. Nominal gap for the 8 mm probe on AISI 4140 steel is −10.0 VDC ± 0.5 V. A reading outside −8 V to −12 V indicates probe drift, cable damage, or connector contamination — not necessarily a real vibration event.

Symptom: Intermittent OK/NOT OK relay chatter on the 3500 rack
Ninety percent of the time this is a connector issue. Inspect the coaxial junction between the integral cable and the extension cable. Moisture ingress at this point — especially in outdoor or wash-down environments — causes impedance fluctuation that the monitor interprets as a vibration spike. Clean with contact cleaner, re-torque to spec, and apply self-amalgamating tape as a moisture barrier.

Replacement procedure — key steps:

1. Record baseline gap voltage before removal. Note the exact reading at the driver terminal — you will use this to set the new probe to the same gap.
2. De-energise the driver (remove the −24 VDC supply to the Proximitor). Do not simply bypass the monitor — the driver must be powered down to avoid false trips during probe swap.
3. Match the extension cable. The -05- suffix means a 5 m extension. Substituting a 10 m cable changes total system capacitance and shifts the scale factor. If you must use a different length, recalibrate the driver gap voltage using the 3300 XL calibration procedure (BN document 141193-01).
4. Set the gap mechanically. Use a non-ferrous feeler gauge or a calibrated gap-setting tool. Target gap: approximately 1.0 mm (40 mil) for the centre of the linear range. Verify with a DVM at the driver output — you want −10.0 VDC ±0.2 V.
5. Verify OK status on the monitor before returning the machine to service. Check both the OK relay and the vibration channel output against a known reference (e.g., a calibrated shaker or a static gap check).
6. No DIP switches or firmware to configure on the probe itself — the 330103 is a passive sensing element. All configuration lives in the driver (Proximitor) and the monitor rack. If you are replacing the driver simultaneously, confirm the driver part number matches the -02- (standard) driver code.

Common fault codes on the 3500/42M monitor:

• OK LED off, gap voltage < −18 V — Open circuit in probe or extension cable. Check cable continuity end-to-end.
• OK LED off, gap voltage > −2 V — Short circuit or probe tip contact with shaft. Inspect probe tip and re-gap.
• Vibration reading pegged at full scale — Driver supply voltage out of range or wrong driver model installed. Verify −24 VDC supply and driver part number.
• Noisy signal, high broadband floor — Ground loop between probe shield and machine frame. Verify single-point grounding at the driver chassis.

Reliability in Harsh Conditions

The 3300 XL probe body is machined from 316 stainless steel with a hermetically sealed tip assembly. The integral cable uses a PTFE-insulated coaxial core inside a stainless-steel armoured braid — not a standard PVC cable. This matters in the field.

In steam turbine applications, the probe tip routinely sees oil mist at 100 °C+ and vibration levels that would destroy a standard sensor within weeks. The 330103 series is rated to 121 °C continuous at the probe body, with the tip capable of short-term excursions to 150 °C in high-temperature variants. The stainless armour resists the mechanical fatigue caused by shaft-induced vibration transmitted through the probe holder — a failure mode that kills cheaper probes in under a year.

In offshore and coastal installations, salt-laden air attacks connector joints. The coaxial connector on the -02-00 variant uses gold-plated contacts and a precision-machined body that maintains impedance integrity even after years of thermal cycling and humidity exposure. We have seen original Bently Nevada probes pulled from service after 15+ years of continuous operation in LNG plants — still within calibration.

Vibration endurance: the probe assembly is qualified to withstand 20 g sinusoidal vibration across 10–2,000 Hz per IEC 60068-2-6. In practice, this means the probe survives the very vibration events it is measuring — including the high-amplitude transients during machine runup and coastdown that stress every component in the measurement chain.
