Bently Nevada 330104-00-23-10-02-00 – 8mm Eddy-Current Proximity Transducer | 3300 XL Series Platform
Engineering Background: The Bently Nevada 3300 XL Series represents the industry benchmark for non-contacting eddy-current measurement in rotating machinery protection. Developed by Baker Hughes (Bently Nevada), this platform has been deployed across gas turbines, steam turbines, compressors, and pumps in critical process industries worldwide for over three decades.
Product Positioning: The 330104-00-23-10-02-00 is an 8mm diameter proximity transducer engineered for radial shaft vibration, axial position (thrust), and differential expansion measurement. It operates as part of a three-component system (transducer + extension cable + proximitor/oscillator) and is fully compatible with the 3300 XL signal conditioning ecosystem. This part number is a direct OEM replacement and is widely specified in turbomachinery OEM documentation and API 670 compliant monitoring systems.

System Architecture & Signal Flow
The 330104-00-23-10-02-00 operates within the standard Bently Nevada three-component eddy-current measurement chain:
- Proximity Transducer (330104-00-23-10-02-00): Generates a high-frequency electromagnetic field; detects shaft surface eddy-current perturbations and converts displacement to a proportional voltage signal via the integral coil and cable.
- Extension Cable (330130 series): Transmits the raw oscillator signal from the transducer tip to the proximitor; total system cable length must be matched to the proximitor calibration (typically 5 m or 9 m system).
- Proximitor / Oscillator-Demodulator (330180 XL NSv): Conditions the raw signal, provides –24 VDC excitation, and outputs a calibrated DC voltage (–1 to –21 VDC) proportional to gap distance for input to the 3500 monitoring rack or DCS/PLC.
Note: Total system cable length (transducer integral cable + extension cable) must match the proximitor’s calibrated system length. Mixing unmatched cable lengths will introduce sensitivity error.

Technical FAQ
Q: Is the 330104-00-23-10-02-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The transducer outputs a standard –1 to –21 VDC signal via the 330180 XL NSv proximitor, which is fully compatible with 3500/40M and 3500/42M proximity monitor modules.
Q: What is the difference between the -02-00 and -00-00 connector suffix?
A: The -02-00 suffix designates a 2-pin MIL-C-5015 style armored connector. The -00-00 suffix uses a standard unarmored connector. Specify based on your installation environment and existing cable termination.
Q: Can this transducer be used for axial position (thrust) measurement?
A: Yes. The 330104 series is suitable for both radial vibration and axial position applications when paired with the appropriate proximitor and 3500 rack monitor card configured for position measurement.
Q: What target material is required for accurate measurement?
A: The standard calibration is for AISI 4140 steel. For other target materials (stainless steel, titanium, Inconel), a material-specific calibration curve or correction factor must be applied. Consult Bently Nevada application note for non-standard target materials.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all verified units. New-in-box units carry the original manufacturer warranty where applicable.
