Bently Nevada 330905-00-19-10-02-CN – Eddy Current Proximity Probe | 3300 NSv Platform
Engineering Background
The Bently Nevada 3300 NSv Series represents the industry benchmark for non-contacting eddy current measurement in rotating machinery protection. Designed for continuous, real-time shaft vibration and position monitoring, the 330905-00-19-10-02-CN is a factory-configured proximity probe optimized for turbomachinery, compressors, pumps, and critical rotating assets where API 670 compliance is mandatory.
Product Positioning
This probe is the primary sensing element in a complete 3300 NSv transducer system, working in conjunction with a compatible extension cable (3300 XL series) and proximitor/oscillator driver. It delivers sub-micron resolution displacement measurements with exceptional linearity across the full operating range — making it the preferred choice for OEM integrators and plant reliability engineers worldwide.

System Architecture & Signal Flow
The 330905-00-19-10-02-CN operates as the sensing element in a three-component transducer system:
- Proximity Probe (330905-00-19-10-02-CN) — Generates an oscillating electromagnetic field; detects eddy current changes induced by the rotating target shaft.
- Extension Cable (3300 XL Series) — Transmits the high-frequency RF signal from the probe tip to the proximitor driver. Cable length must be matched to the probe’s calibrated system.
- Proximitor / Oscillator Driver (3300 NSv) — Demodulates the RF signal into a DC voltage proportional to the gap distance. Outputs –2 VDC (near gap) to –18 VDC (far gap) at 7.87 V/mm scale factor.
The DC output connects directly to Bently Nevada 3500 Series rack monitors, DCS analog input cards, or standalone vibration monitors for alarm/trip logic.

Technical FAQ
Q: Is the 330905-00-19-10-02-CN a direct replacement for the 330905-00-19-10-01-CN?
A: The –02 suffix denotes a 5 m integral cable vs. the –01’s 1 m cable. Electrically identical; ensure your extension cable length is adjusted accordingly to maintain system calibration.
Q: Can this probe be used with non-Bently Nevada monitors?
A: Yes. The –18 VDC to –2 VDC output is compatible with any analog input accepting a 4–20 mA or voltage signal via a signal conditioner. Direct connection to 3500 Series racks is plug-and-play.
Q: What target materials are supported?
A: Optimized for AISI 4140 steel. Performance on stainless steel, titanium, or non-ferrous targets requires a target-specific calibration curve — contact us for application engineering support.
Q: Is a calibration certificate available?
A: Factory calibration certificates can be provided upon request. Third-party NIST-traceable recalibration is also available through our partner laboratories.
Q: What is the minimum order quantity?
A: Single units available. Volume discounts apply for orders of 5+ units.
