330101-00-32-10-02-00 — Stop the Clock on Your Downtime. Ship Today.

Every hour your turbine or compressor sits idle costs real money — lost throughput, penalty clauses, and a maintenance crew standing around waiting for one part. The Bently Nevada 330101-00-32-10-02-00 3300 XL 8 mm eddy-current proximity transducer is on the shelf in Xiamen right now. We don’t quote lead times in weeks. We quote in hours. Place your order before 14:00 CST and it moves today.

This is not a refurbished unit. Not a grey-market pull. It is a 100% original Bently Nevada 3300 XL Series transducer, procured through verified industrial supply channels, bench-inspected before dispatch, and packed for air freight. If your machinery protection system is throwing Alert 1 or you’ve already tripped on Danger, this is the part that gets you back online.

Troubleshooting & Replacement Tips

Ten years of field calls teach you that most 330101-series failures fall into three buckets. Know which one you’re dealing with before you pull the probe.

1. Gap Voltage Out of Range (most common)
The 3300 XL system expects a static gap voltage between −10 VDC and −12 VDC at the nominal 1.0 mm air gap. If your Proximitor® is reading outside −7 V to −15 V, the probe tip is either damaged, the target material has changed, or the probe is simply worn out. Before condemning the probe, check the extension cable connector at the Proximitor® input — a corroded BNC or loose set-screw is responsible for roughly 30% of “probe failures” that aren’t actually probe failures.

2. Intermittent OK/Not OK on the 3500 Monitor
This almost always traces to the armored cable jacket. In high-vibration installations — especially on compressor bearing housings — the cable fatigues at the conduit entry point. Flex the cable near the probe body while watching the gap voltage on a DMM. If the reading jumps, the internal conductor is cracked. Replace the full probe-and-cable assembly; splicing is not acceptable under API 670.

3. Replacement Configuration Checklist
When you install the 330101-00-32-10-02-00, run through this before you close the junction box:

• Confirm the Proximitor® driver is the 8 mm variant — do not mix with 5 mm or 11 mm drivers. The scale factor will be wrong and your monitor will trip on false readings.
• Set the air gap to 1.0 mm ± 0.1 mm using a feeler gauge. Verify static gap voltage is −10.5 V ± 0.5 V at the Proximitor® output.
• Torque the probe locknut to 20 N·m. Under-torquing causes thermal drift; over-torquing cracks the ceramic tip.
• Route the armored cable with a minimum bend radius of 50 mm. Tighter bends will fail within 6 months in a vibrating environment.
• After installation, perform a slow-roll check at <600 RPM to verify runout is within the machine’s baseline. If runout has increased, inspect the shaft target area for corrosion or mechanical damage before returning to full speed.
• No firmware update is required on the 3500 monitor when swapping a like-for-like 330101 probe — the channel configuration is stored in the monitor rack, not the probe.

Common Fault Codes on Bently Nevada 3500 Rack:

• Not OK (NO K) LED solid: Gap voltage outside −2 V to −18 V window — check probe gap and cable continuity first.
• Alert 1 trip: Vibration amplitude exceeded setpoint — verify probe gap hasn’t shifted due to thermal growth before assuming a bearing event.
• Danger trip: Do not reset and restart without physically inspecting the probe gap and shaft condition. A false Danger caused by a failed probe is still a Danger until proven otherwise.

Reliability in Harsh Conditions

The 3300 XL probe body is constructed from 316 stainless steel with a ceramic-filled epoxy tip. It was designed for the environments where most sensors give up — not the clean instrument room, but the bearing housing of a 40 MW steam turbine running at 3,000 RPM in a petrochemical plant where ambient temperature swings 80 °C between winter shutdown and summer full-load operation.

The armored cable uses a stainless steel braid over a PTFE-insulated conductor, giving it resistance to oil mist, H₂S atmospheres, and the kind of mechanical vibration that destroys standard instrumentation cable in weeks. The MIL-spec connector at the Proximitor® end maintains contact integrity even after hundreds of connect/disconnect cycles during maintenance outages.

ATEX and IECEx certification means this probe can be installed in Zone 1 and Zone 2 hazardous areas without additional barriers — a critical factor for refineries and LNG terminals where the alternative is a lengthy ATEX deviation process that delays your restart by days. The operating temperature ceiling of +177 °C at the probe tip covers the vast majority of steam turbine bearing housing installations without derating.

Vibration endurance: the 3300 XL probe is qualified to 20 g continuous vibration across 10–2,000 Hz per IEC 60068-2-6. In practice, this means it outlasts the bearing it is monitoring in most installations — which is exactly what a machinery protection sensor should do.

Global Express Logistics

Our warehouse is in Xiamen, Fujian — one of China’s primary export hubs with direct DHL and FedEx gateway access. Here is exactly what happens after you confirm your order:

• Same day (orders before 14:00 CST): Unit is pulled from shelf, inspected, photographed, and packed in anti-static foam with a rigid outer carton rated for air freight handling.
• Day 1: Shipment handed to DHL Express or FedEx International Priority. AWB number sent to your email within 2 hours of pickup scan.
• Day 2–3: Delivery to most destinations in Southeast Asia, Japan, South Korea, and Australia. Middle East and Europe typically Day 3–4. North America Day 3–5 depending on customs clearance speed.
• Export documentation: Commercial invoice, packing list, Certificate of Origin, and HS code declaration (HS 9031.80) provided with every shipment. MSDS available on request for ATEX-certified units.
• Emergency freight: For plant shutdowns where every hour counts, we can arrange next-flight-out courier with hand-carry service to major hubs. Contact us directly on WhatsApp for this option — it is not available through the standard checkout flow.

We do not use postal services or economy freight for industrial components. Every shipment is fully tracked, fully insured, and handled by a named courier with a guaranteed delivery window. If your shipment is delayed by customs, we work the problem with you — not around you.
