Bently Nevada 330101-00-16-10-11-RU – Eddy Current Proximity Probe | 3300 XL Series Platform
Engineering Background: The Bently Nevada 3300 XL Series is the global benchmark for continuous shaft vibration and axial position monitoring in rotating machinery. Deployed across power generation, oil & gas, petrochemical, and heavy industrial sectors, the 3300 XL proximity system delivers API 670-compliant measurement with sub-micron resolution. The 330101-00-16-10-11-RU is a 5 mm tip diameter eddy current probe engineered for demanding environments where measurement accuracy and long-term reliability are non-negotiable.
Product Positioning: This probe is the primary sensing element in the 3300 XL transducer system, working in conjunction with the 330130 extension cable and 3300 XL proximitor sensor to deliver a calibrated 200 mV/mil (7.87 V/mm) output. It is the preferred choice for procurement engineers sourcing OEM-equivalent replacement parts for turbines, compressors, pumps, and gearboxes operating under API 670 machinery protection standards.

- Wide temperature range — qualified to +177°C for hot-section turbine bearing housings
- IP67 sealing — resistant to oil mist, steam, and high-pressure washdown environments
- 316 SS housing — corrosion-resistant in H₂S and chloride-bearing process atmospheres
- Direct OEM replacement — plug-and-play compatibility with existing 3300 XL proximitor and 330130 extension cable assemblies
- -RU certification — meets Russian GOST / TR CU regulatory requirements for certified industrial installations
System Architecture & Signal Flow
The 330101-00-16-10-11-RU operates as part of a three-component transducer system:
- Probe (330101-00-16-10-11-RU) — generates the eddy current electromagnetic field at the shaft surface and converts gap distance to an RF signal
- Extension Cable (330130 series) — transmits the RF signal from probe tip to proximitor; total system cable length must equal 5 m or 9 m to match factory calibration
- Proximitor Sensor (3300 XL) — demodulates the RF signal and outputs the calibrated –24 VDC proportional voltage to the monitoring rack or DCS input card
Note: Mixing probe, cable, and proximitor from different calibrated system lengths will introduce measurement error. Always verify total cable length matches the proximitor calibration label before installation.

Technical FAQ
Q: Can this probe be used with a 3300 NSv or 7200 series proximitor?
A: No. The 330101 probe is factory-calibrated for the 3300 XL proximitor. Using it with NSv or 7200 series proximitors will result in sensitivity errors and invalid measurements. Contact Konmask for the correct probe-proximitor pairing for your system.
Q: What is the significance of the -RU suffix?
A: The -RU suffix denotes a variant certified for use in the Russian Federation under applicable technical regulations (TR CU / GOST). Functionally and electrically identical to the standard variant; the suffix only affects certification documentation.
Q: Is this probe compatible with non-steel shaft materials?
A: The factory calibration is based on AISI 4140 steel. For Inconel, titanium, aluminum, or other alloys, a material correction factor must be applied. Contact our engineering team for a target material correction table.
Q: What warranty is provided?
A: Konmask provides a 12-month warranty against manufacturing defects on all verified OEM units. Warranty claims require return of the defective unit for inspection and failure analysis.
Q: Can you provide a certificate of conformance (CoC)?
A: Yes. CoC, calibration records, and full traceability documentation are available upon request at no additional charge for every order.
