Bently Nevada 330104-00-18-10-02-00 Proximity Transducer

330104-00-18-10-02-00 In Stock — Every Hour of Downtime Costs More Than This Module

Your turbine is tripped. The control room is dark. Maintenance is standing by. The 3300 XL proximity transducer that just failed costs a fraction of what one hour of unplanned shutdown burns through — and we have 330104-00-18-10-02-00 ready to ship from Xiamen today. No lead time games. No broker markups. Direct dispatch via DHL Express or FedEx Priority to your plant gate.

This is the exact 5 mm eddy-current proximity transducer used in Bently Nevada’s 3300 XL machinery protection platform. It is the primary sensing element for radial shaft vibration, axial position, and differential expansion measurement on rotating equipment — steam turbines, centrifugal compressors, boiler feed pumps, and gearboxes operating under API 670 protection schemes. When this part fails, the machine trips. When you have a verified replacement on the shelf, the machine restarts.

Troubleshooting & Replacement Tips

Step 1 — Confirm the fault before pulling the transducer. A 3500 Series monitor showing a NOT OK or a gap voltage outside the −10 V ± 1 V window at nominal gap does not automatically mean the transducer is dead. Check the extension cable first — the 330130 series cable is the most common failure point in field installations due to connector corrosion and jacket abrasion at conduit entry points. Disconnect the extension cable at the Proximitor end and measure DC output directly. If output recovers, the transducer is fine; replace the cable.

Step 2 — Verify system compatibility before installing the 330104-00-18-10-02-00. This is a 5 mm tip system. It must be paired with a 3300 XL 5 mm Proximitor (e.g., 330180-51-00). Connecting it to an 8 mm driver (330180-90-00 series) will produce a sensitivity error of approximately 30% — the monitor will not trip correctly, and you will have a false sense of protection. Check the Proximitor label before you thread in the new transducer.

Step 3 — Total cable system length matters. The 330104-00-18-10-02-00 has an 18-inch (457 mm) integral cable. Add your extension cable length. The 3300 XL 5 mm system is calibrated for either a 5 m or 9 m total system. Mixing lengths shifts the sensitivity curve. Refer to Bently Nevada document 141536-01 for system length options and corresponding Proximitor part numbers.

Step 4 — Gap setting after installation. Thread the transducer into the bracket and set the gap to mid-linear range: 50 mil (1.27 mm) nominal, which should read approximately −10 VDC at the Proximitor output. Use a non-ferrous feeler gauge or a calibrated gap tool. Do not rely on the monitor’s gap alarm to confirm correct installation — set the gap physically, then verify the DC output with a multimeter before re-energizing the protection system.

Step 5 — Common fault codes on 3500 monitors after transducer swap.

• NOT OK (steady) — Gap voltage out of range. Recheck gap distance and cable system length.
• NOT OK (intermittent) — Connector intermittency. Inspect the 10-32 coaxial connector at the transducer-to-extension cable junction. Clean with contact cleaner and re-torque to spec (0.9 N·m).
• High vibration alarm immediately after restart — Transducer tip contaminated with ferrous debris from the shaft. Shut down, clean the tip, and re-gap.
• Sensitivity drift over time — Target material mismatch. If the shaft is Inconel or titanium, standard AISI 4140 calibration will read low. Contact us for material correction factor data.

Reliability in Harsh Conditions

The 330104-00-18-10-02-00 is not a lab instrument. It lives inside bearing housings, turbine pedestals, and compressor casings where ambient temperatures swing from −35 °C during cold-start to +177 °C at steady-state operation. The 316L stainless steel housing resists H₂S, chloride-laden process atmospheres, and the caustic wash-downs common in petrochemical turnarounds. IP67 sealing keeps moisture out of the coil assembly even in steam-saturated environments.

Vibration is the operating environment, not the enemy. The integral cable design eliminates the field-assembled connector joint that is the primary failure mode on older 3300 series transducers — there is no junction between the coil and the cable to work loose under 1g continuous vibration. The gold-plated 10-32 coaxial connector maintains contact resistance below 5 mΩ across the full temperature range, preventing the signal noise that triggers nuisance trips on sensitive 3500 monitors.

ATEX and IECEx certification covers Zone 1 and Zone 2 hazardous area installations. The transducer has been tested to withstand the thermal cycling, mechanical shock, and EMI environments defined in API 670 Annex D — the same standard your machinery protection engineer used when specifying the original installation.

Every shipment includes a commercial invoice with accurate HS code classification (HS 9031.80) for smooth customs clearance. We prepare all export documentation — packing list, certificate of origin, and material safety data — in advance so your import broker has everything needed on arrival. For plants in free-trade zones or with bonded warehouse arrangements, contact us to discuss direct-to-bond shipping options.

Fragile industrial sensors require more than a cardboard box. The 330104-00-18-10-02-00 ships with a protective tip cap installed, coaxial connector covered, and the unit wrapped in anti-static foam inside a rigid outer carton. Cable is coiled to minimum bend radius to prevent coil damage in transit. We have shipped thousands of proximity transducers to active plant sites across 60+ countries without a single transit damage claim.
