Bently Nevada 330104-13-20-50-02-00 – 8mm Eddy Current Proximity Probe | 3300 XL Series
The Bently Nevada 330104-13-20-50-02-00 is a precision 8mm eddy current proximity probe from the industry-standard 3300 XL Series, engineered for continuous non-contact measurement of shaft radial vibration, axial position, and differential expansion in critical rotating machinery. Procurement engineers worldwide specify this probe as the cornerstone of API 670-compliant machinery protection systems.
Product Positioning: Designed for turbomachinery applications — steam turbines, gas turbines, centrifugal compressors, and large pumps — where real-time shaft dynamics data is essential for predictive maintenance and plant safety. The 330104-13-20-50-02-00 integrates natively with Bently Nevada 3300 XL NSv Proximitors and System 1 condition monitoring software, providing a fully validated measurement chain from probe tip to control room.

System Architecture & Signal Flow
The 330104-13-20-50-02-00 operates as part of a three-component eddy current measurement chain:
- Probe (330104-13-20-50-02-00): Generates a 1–2 MHz electromagnetic field directed at the rotating shaft. Gap changes modulate field impedance proportionally to displacement.
- Extension Cable (330130 Series): Transmits the modulated signal from probe tip to proximitor with minimal signal loss. Total cable length is factory-matched to the probe.
- Proximitor/Driver (3300 XL NSv, 330180 Series): Demodulates the signal and outputs a DC voltage proportional to probe-to-target gap. Output feeds 3500 Series rack monitors or DCS/PLC systems via 4–20 mA or voltage outputs.
Important: Probe, extension cable, and proximitor must be ordered as a matched system. Mixing cable lengths from different part numbers will affect calibration and scale factor accuracy.

Technical FAQ
- Q: Is the 330104-13-20-50-02-00 compatible with legacy 3300 Series (non-XL) proximitors?
- A: No. The 3300 XL probe is designed exclusively for 3300 XL NSv proximitors. Mixing with legacy 3300 (non-XL) drivers produces incorrect scale factor and measurement errors. Verify your proximitor model before ordering.
- Q: What target material is required for standard calibration?
- A: Standard calibration is for AISI 4140 steel. For other alloys (stainless steel, titanium, Inconel), a material-specific calibration curve is required. Contact Konmask for custom calibration options.
- Q: Can this probe be installed in hazardous (Ex) classified areas?
- A: Yes, with an appropriate Zener barrier or galvanic isolator in the signal loop. Confirm the specific Ex certification (ATEX, IECEx, FM) required for your installation zone before specifying.
- Q: What is the difference between the -02-00 and -02-05 suffix?
- A: The suffix denotes connector and termination options. -02-00 is the standard industrial connector configuration. Refer to the Bently Nevada 3300 XL product catalog for full suffix decode table.
- Q: Is expedited shipping available for shutdown or turnaround emergencies?
- A: Yes. Konmask maintains ready stock for critical spares. Contact us directly for same-day dispatch options on in-stock units.
