Bently Nevada 330104-00-06-10-02-00 Proximity Probe

330104-00-06-10-02-00 In Stock — Every Hour of Downtime Has a Price Tag

Your compressor tripped at 02:00. The vibration monitor is screaming a Danger High alarm. The proximity probe is dead — and your maintenance window is closing fast. This is not a theoretical scenario; it happens on gas turbines, centrifugal compressors, and boiler feed pumps every week across refineries and power plants worldwide. The Bently Nevada 330104-00-06-10-02-00 is on the shelf in Xiamen right now. We ship the same business day. That is the only number that matters when your production line is standing still.

The 330104-00-06-10-02-00 is a core sensing element of the 3300 XL 8mm Proximity Transducer System — the eddy-current platform that has been the backbone of rotating machinery protection for decades. It delivers non-contact, continuous measurement of radial shaft vibration, axial position, and differential expansion. Drop-in compatible with your existing 3300 XL driver and extension cable assemblies. No monitor recalibration. No firmware update. Bolt it in, gap it correctly, verify the DC gap voltage, and you are back online.

Troubleshooting & Replacement Tips

Symptom: Monitor shows –24 VDC or 0 VDC on the gap channel
This is the classic open-circuit or short-circuit failure signature. A reading of –24 VDC (or near rail) means the probe tip is either missing, broken, or the cable is open. A reading near 0 VDC means the probe is shorted — usually from cable crush damage or probe tip contact with the shaft. In both cases, the probe must be replaced before the machine can be safely restarted.

Symptom: Intermittent vibration spikes with no process change
Check the probe cable routing first. Armored cable that has been kinked or pinched near a hot surface will develop intermittent opens under thermal cycling. Wiggle the cable at the probe body and at the junction box while watching the gap voltage. If the reading fluctuates more than ±0.5 VDC, the cable is compromised — replace the full probe assembly, not just the cable.

Replacement procedure — field checklist:

1. Confirm machine is at rest and locked out. Do not replace a proximity probe on a running machine.
2. Note the existing gap voltage before removal (document it — this is your baseline for the new probe).
3. Remove the probe by unscrewing from the bracket. Count the number of turns to the original gap depth and record it.
4. Install the new 330104-00-06-10-02-00. Thread in to the same depth as the original, then fine-adjust.
5. Power the system and measure DC gap voltage at the driver output. Target: −10.0 to −11.0 VDC for a 1.0 mm gap on a steel target. Adjust probe depth in 0.25 mm increments until within spec.
6. Verify the total system cable length (probe + extension) matches the driver calibration. The 3300 XL driver is calibrated for specific total lengths (5 m, 9 m, or 15 m). Mixing lengths without recalibration will introduce a sensitivity error.
7. Lock the probe in position with the locknut. Torque to manufacturer spec — do not over-torque on aluminum brackets.
8. Perform a slow-roll check. Vibration reading should be below 0.5 mil pk-pk on a balanced shaft at slow roll. If higher, check probe alignment and target surface condition.
9. Clear the monitor alarms and return the machine to service.

Common fault codes on 3500 Series monitors:

• OK LED off / Not OK relay energized: Gap voltage out of range. Probe gap incorrect or probe failed.
• Danger High alarm, no process change: Probe cable intermittent or probe tip contaminated with conductive debris.
• Buffered output reads rail voltage: Driver not receiving signal from probe — check BNC connection at driver input and at junction box.

Configuration note — extension cable matching: The 330104-00-06-10-02-00 probe ships with a 5 m integral cable. If your installation requires a 9 m or 15 m total system length, you must add the appropriate 330130 series extension cable. Do not use a non-matched extension — the driver’s internal calibration resistor is set for a specific total cable capacitance. A mismatch of even one cable length step will shift sensitivity by 5–8%, which is enough to cause nuisance trips or, worse, missed danger conditions.

Reliability in Harsh Conditions

The 3300 XL probe body is constructed from 316 stainless steel with a PEEK (polyether ether ketone) tip insert — a material chosen specifically for its resistance to hydrocarbon fluids, H₂S environments, and steam. The armored cable jacket withstands continuous mechanical abrasion from cable trays and conduit edges that would destroy standard instrumentation cable within months.

Vibration endurance: the probe assembly is qualified to withstand 20 g sinusoidal vibration across 10–2000 Hz — relevant because the probe bracket itself sits on machinery that is vibrating. A probe that cannot survive its own installation environment is useless. The 330104-00-06-10-02-00 has been deployed on gas turbine bearing housings where ambient vibration levels routinely exceed 5 g broadband.

Temperature cycling: the probe body rating of +177°C covers the vast majority of hot-section turbine and compressor bearing housing applications. The cable insulation is rated for continuous exposure at these temperatures without jacket cracking or insulation breakdown — a failure mode that is common in cheaper aftermarket alternatives and that produces exactly the intermittent fault signatures described in the troubleshooting section above.

Humidity and ingress: the probe connector and cable terminations are sealed to IP67 when properly mated. In offshore and coastal environments where salt fog and condensation are constant, this matters. Corroded BNC connectors are a leading cause of false vibration alarms that waste maintenance hours chasing a sensor problem that looks like a machinery problem.

Global Express Logistics

Our warehouse is located in Xiamen, Fujian, China — one of the most logistics-efficient export hubs on the Chinese coast, with direct access to DHL, FedEx, and UPS international gateways. Orders confirmed before 15:00 CST ship the same business day. Here is what the timeline looks like from your purchase order to your maintenance bay:

• Day 0 (order confirmed): Unit pulled from shelf, inspected, packed in anti-static foam-lined carton with moisture barrier. Commercial invoice and packing list generated. Export declaration filed.
• Day 1: Handed to DHL Express or FedEx International Priority at Xiamen pickup. Tracking number issued to buyer within 2 hours of dispatch.
• Day 2–4 (most destinations): Delivery to Southeast Asia, Middle East, Europe, and North America via express air freight. Customs clearance handled by the courier’s brokerage network.
• Day 3–6 (remote destinations): South America, West Africa, and remote island locations may require one additional transit day depending on local customs processing speed.

We prepare full export documentation: commercial invoice with HS code, packing list, certificate of origin, and — on request — a material safety data sheet and certificate of conformance. For buyers in countries with import duty exemptions on industrial automation components, we can provide the documentation required to support your customs declaration. Contact us before shipment if you have specific documentation requirements.

For critical emergency shipments where standard express is not fast enough, we can arrange charter courier or hand-carry service to your site. This is not a marketing claim — we have done it. If your plant is down and every hour costs real money, call us directly on WhatsApp and we will discuss options.
