Bently Nevada 330104-00-11-10-01-00 Proximity Probe

330104-00-11-10-01-00 Down? Every Minute of Shaft Vibration Blackout Costs You — We Ship Same Day

Your turbine is tripped. The DCS is throwing Probe Fault or Not OK alarms. The 3500 rack has gone into danger state. You’ve already confirmed the Proximitor output is sitting at –24 VDC with no AC component — the probe is dead. You need a 330104-00-11-10-01-00 on-site before the next shift, not in three weeks.

We stock the Bently Nevada 330104-00-11-10-01-00 at our Xiamen warehouse. No broker delays, no “lead time TBD” runaround. Place your inquiry now and we’ll confirm availability and dispatch within hours. For rotating machinery protection, every hour without a functioning proximity probe is a liability your insurance team doesn’t want to hear about.

Quick Technical Datasheet

Troubleshooting & Replacement Tips

Fault Scenario 1 — Proximitor output stuck at –24 VDC (no AC ripple): This is the classic open-circuit probe failure. The eddy current coil inside the probe tip has failed or the integral cable has a break near the connector. Swap the probe first before condemning the Proximitor. Measure DC bias at the Proximitor output: –24 VDC = probe open circuit; 0 VDC = probe short circuit; –10 to –18 VDC = normal operating range.

Fault Scenario 2 — Intermittent “Not OK” with vibration readings spiking to full scale: Nine times out of ten this is a cable integrity issue at the probe-to-extension cable junction. Flex the connector while watching the Proximitor output. If the signal drops in and out, the problem is mechanical — replace the probe and inspect the extension cable (330130 series) for jacket damage or connector corrosion.

Fault Scenario 3 — Probe reads OK but vibration baseline has shifted 2–4 mils with no process change: Check the gap. Thermal cycling can cause probe mounting hardware to creep. Re-gap to the midpoint of the linear range (approximately 1.0–1.5 mm / 40–60 mil) using a non-ferrous feeler gauge or a calibrated gap meter. Do not rely on the Proximitor DC output alone without a physical gap verification.

Replacement Procedure — Key Steps:

• De-energize the Proximitor supply rail before disconnecting the probe. Hot-swapping is not recommended — the inrush can cause a transient alarm on the 3500 monitor.
• Record the existing gap (DC bias voltage) before removal. Target the same gap on reinstallation to avoid a full recalibration cycle.
• The 330104-00-11-10-01-00 is a direct form-fit-function replacement. No Proximitor recalibration is required when replacing with the same part number — the system sensitivity and linear range are factory-matched.
• Inspect the probe mounting threads (M10 x 1.0 on most installations) for galling before reinstalling. Apply anti-seize compound sparingly — do not contaminate the probe tip area.
• After installation, verify DC bias output at the Proximitor is within –10 to –18 VDC before re-enabling the monitor channel. Confirm the “OK” relay closes and the 3500 rack clears the fault before returning the machine to service.
• Log the replacement in your machinery history file with the new probe serial number, installation gap, and DC bias reading. This data is critical for trend analysis during the next outage.

Common Mistake to Avoid: Do not mix 3300 XL probes with 3300 series (non-XL) Proximitors. The XL system uses a different oscillator frequency. Mixing components will result in incorrect sensitivity and potentially dangerous false readings on the 3500 monitor. Always verify the Proximitor model number before ordering a replacement probe.

Reliability in Harsh Conditions

The 330104-00-11-10-01-00 was not designed for a clean lab environment. It was built for the conditions you actually work in — bearing pedestals running at 80°C ambient, compressor trains bathed in lube oil mist, coastal installations where salt air attacks every exposed connector, and offshore platforms where the deck vibrates at 15–20 Hz continuously.

The 316 stainless steel housing resists corrosion in H₂S-rich atmospheres common in oil and gas processing. The epoxy-sealed probe tip prevents hydrocarbon ingress that would otherwise detune the eddy current coil and shift the sensitivity curve. The integral cable jacket is rated for continuous immersion in lubricating oil — a condition that destroys standard instrumentation cable within months.

Bently Nevada’s 3300 XL series has accumulated decades of field data across gas turbine installations in the Middle East, steam turbine fleets in Southeast Asian power plants, and centrifugal compressor trains in North Sea platforms. The mean time between failure (MTBF) data from these installations is why API 670 references the 3300 XL as a benchmark system. When you install a 330104-00-11-10-01-00, you are not experimenting — you are deploying a solution with a proven track record measured in millions of operating hours.

Vibration tolerance: the probe assembly withstands 20g continuous vibration per IEC 60068-2-6, which covers the resonance frequencies of most rotating machinery foundations. Shock resistance is rated to 50g per IEC 60068-2-27 — sufficient for the mechanical transients that occur during machine trips and emergency shutdowns.

Global Express Logistics

Our Xiamen warehouse is positioned specifically for rapid international dispatch. Xiamen Gaoqi International Airport (XMN) has direct cargo connections to DHL and FedEx international hubs, enabling next-flight-out shipments to most major industrial regions.

Typical transit times from Xiamen:

• Southeast Asia (Singapore, Thailand, Malaysia, Indonesia): DHL Express / FedEx International Priority — 1 to 2 business days
• Middle East (UAE, Saudi Arabia, Qatar, Kuwait): DHL Express — 2 to 3 business days
• Europe (Germany, Netherlands, UK, France): FedEx International Priority — 3 to 4 business days
• North America (USA, Canada): DHL Express / FedEx — 3 to 5 business days
• South Asia (India, Pakistan, Bangladesh): DHL Express — 2 to 3 business days
• Australia / New Zealand: FedEx International Priority — 3 to 4 business days

Every shipment includes a full commercial invoice, packing list, and certificate of origin — the documentation your customs broker needs to clear the shipment without delays. For orders requiring an MSDS or material certificate, we provide these as standard for instrumentation components. We have experience with import requirements in regulated markets including India (BIS), the EU (CE documentation), and the Gulf Cooperation Council states.

For genuine emergency situations — plant down, production stopped — contact us directly on WhatsApp. We can arrange same-day dispatch for orders confirmed before 15:00 CST and coordinate with your freight forwarder if you have a preferred carrier account. We do not add handling markups to freight costs. You pay the carrier rate, nothing more.

All packages are double-boxed with foam padding. The probe tip is protected with a machined plastic cap and the connector is individually bagged to prevent transit damage. We have shipped thousands of precision instrumentation components internationally without a single transit damage claim — packaging is not an afterthought here.
