Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330103-00-16-50-02-CN | 3300 XL Series
The Bently Nevada 330103-00-16-50-02-CN is a high-precision eddy-current proximity transducer from the industry-standard 3300 XL Series. Engineered for continuous, real-time shaft vibration and position measurement in critical rotating machinery, this transducer is the first-choice specification for plant engineers who cannot afford unplanned downtime. Its 5 mm sensing range, 200 mV/mil (7.87 V/mm) sensitivity, and -18 VDC supply make it a direct drop-in for existing 3300 XL installations worldwide.

Application-Specific FAQ
Q: Is the 330103-00-16-50-02-CN compatible with the 3500 monitoring rack?
A: Yes. When paired with a 330180 Proximitor® driver, the output signal (–18 VDC, 200 mV/mil) is fully compatible with the 3500/42M and 3500/40M monitor modules.
Q: What is the difference between the -02-CN and -02-00 connector suffix?
A: The -02-CN uses the Chinese national connector standard; the -02-00 uses the international MIL-spec connector. Both are electrically identical — only the physical connector body differs.
Q: Can this probe be used on non-ferrous targets (aluminium, titanium)?
A: The standard calibration is for AISI 4140 steel. Non-ferrous targets require a target-material correction factor; contact our engineering team for recalibration data.
Q: What is the maximum shaft speed this transducer can monitor?
A: The 0–10,000 Hz frequency response supports shaft speeds up to 600,000 RPM for 1× vibration components, well beyond typical turbomachinery operating ranges.
Q: Do you provide ATEX-certified configurations?
A: The probe itself is intrinsically safe when used with a certified IS barrier. We can supply the complete ATEX-certified system (probe + barrier + driver); please specify your zone classification when ordering.
