Bently Nevada 330103-00-02-05-02-00 – 8mm Eddy Current Proximity Probe | 3300 XL Transducer System
Engineering Background: The Bently Nevada 3300 XL 8mm Proximity Transducer System is the industry benchmark for continuous, non-contact measurement of shaft radial vibration, axial position, differential expansion, and eccentricity in rotating machinery. Developed by Baker Hughes (Bently Nevada), this system is deployed across power generation, oil & gas, petrochemical, and heavy industrial sectors worldwide.
Product Positioning: The 330103-00-02-05-02-00 is a precision 8mm eddy current proximity probe engineered for integration into the 3300 XL transducer system. It delivers reliable, high-resolution displacement measurements in harsh industrial environments, making it the preferred choice for procurement engineers specifying condition monitoring instrumentation for critical rotating assets.

System Architecture & Signal Flow
The 330103-00-02-05-02-00 probe operates as the sensing element in a three-component eddy current transducer system:
- Proximity Probe (330103-00-02-05-02-00): Generates a high-frequency electromagnetic field at the probe tip. Eddy currents induced in the conductive target (shaft) attenuate the field proportionally to the gap distance.
- Extension Cable (3300 XL series): Transmits the modulated RF signal from the probe to the Proximitor with minimal loss.
- Proximitor® Sensor (3300 XL): Demodulates the RF signal and outputs a calibrated DC voltage (–24 VDC scale) to the monitoring system (e.g., 3500 Series rack).
The resulting analog output is directly compatible with Bently Nevada 3500 Series monitoring racks, DCS analog input cards, and safety system interfaces.

Technical FAQ
Q: Is the 330103-00-02-05-02-00 a direct replacement for older 330103 series probes?
A: Yes. The 3300 XL 8mm probe series maintains backward compatibility with 3300 XL Proximitor sensors. Verify the extension cable system code matches your installed Proximitor.
Q: What target material is required for accurate measurement?
A: The probe is calibrated for AISI 4140 steel (standard shaft material). For other alloys (stainless, titanium, Inconel), a material correction factor must be applied. Contact our engineering team for recalibration data.
Q: Can this probe be used with third-party monitoring systems?
A: The –24 VDC analog output is compatible with most DCS and safety system analog input modules. Confirm input impedance ≥ 10 kΩ and voltage range –24 VDC to 0 VDC with your system vendor.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. For large quantities or urgent plant shutdowns, contact [email protected] for expedited options.
Q: Do you provide calibration certificates?
A: Factory calibration data is available for new units. Third-party calibration services can be arranged upon request.
