The Bently Nevada 330881-16-04-189-06-02 is a high-precision metric proximity transducer engineered for continuous shaft vibration and position monitoring in rotating machinery. Part of the industry-standard 3300 XL Series, this eddy-current sensor delivers reliable, real-time displacement measurements in the most demanding industrial environments.
Where This Product Is Used
This proximity transducer is specified by rotating machinery engineers and reliability teams across critical industries:
- Oil & Gas: Centrifugal compressors, gas turbines, and pipeline booster stations where shaft displacement monitoring is mandatory per API 670.
- Power Generation: Steam turbines and generator sets requiring continuous radial vibration surveillance to prevent catastrophic failure.
- Petrochemical & Refining: High-speed process compressors and pumps in hazardous-area installations.
- Marine Propulsion: Shaft monitoring on large diesel engines and reduction gearboxes.
- Pulp & Paper / Heavy Industry: Fan, blower, and large motor bearing monitoring for predictive maintenance programs.

Application-Specific FAQ
Q: Is the 330881-16-04-189-06-02 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The 3300 XL probe series is fully compatible with the 3500 Series rack when used with the correct 3300 XL proximitor. No sensitivity rescaling is required.
Q: What is the difference between the 330880 and 330881 series?
A: The 330880 uses imperial (UNF) threads; the 330881 uses metric (M8 × 1.0) threads. Electrically and functionally they are equivalent. Specify 330881 for metric probe bosses.
Q: Can this probe be used on non-steel targets?
A: The standard calibration is for AISI 4140 steel. For stainless steel, titanium, or other alloys, a target material correction factor must be applied. Contact us for application-specific calibration data.
Q: Do you provide a warranty?
A: All units are covered by Konmask’s 12-month warranty against manufacturing defects. Warranty claims are processed within 5 business days.
Q: Can you supply the full 3300 XL loop (probe + extension + proximitor)?
A: Yes. Contact our team for a complete loop quotation including all matched components.
