Bently Nevada 330103-00-17-10-02-CN – Eddy-Current Proximity Transducer System | 3300 XL Series
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contact, eddy-current shaft vibration and position measurement in rotating machinery. Developed by Baker Hughes (Bently Nevada), these transducer systems are deployed globally in turbines, compressors, pumps, and generators where continuous, high-resolution displacement monitoring is mission-critical.
Product Positioning
The 330103-00-17-10-02-CN is a complete proximity transducer system configured with a 5 mm tip diameter probe, 5-metre (16.4 ft) armored extension cable, and -18 mm threaded housing. The CN suffix designates the China-market / special-order configuration variant. It integrates directly with Bently Nevada 3300 series monitors and Keyphasor® systems, providing a plug-and-play solution for OEM and retrofit installations.

System Architecture & Signal Flow
The 330103-00-17-10-02-CN operates as a three-component eddy-current system:
- Probe (330103 series) – Generates a high-frequency electromagnetic field at the tip; detects changes in gap distance to the conductive target shaft.
- Extension Cable (02 = 5 m) – Transmits the RF oscillator signal between probe and driver with minimal signal loss; armored jacket provides EMI shielding.
- Proximitor® Driver / Oscillator-Demodulator – Converts the impedance change into a DC voltage output proportional to gap distance (–2 to –18 VDC); connects to Bently Nevada 3300 series monitor input cards.
Signal output feeds directly into 3300/16 or 3300/20 monitor channels, enabling real-time alarm, danger, and trip logic per API 670 setpoints.

Technical FAQ
Q: Is the 330103-00-17-10-02-CN compatible with Bently Nevada 3500 series monitors?
A: The 3300 XL transducer system is optimized for 3300 series monitors. Compatibility with 3500 series requires verification of driver impedance and scale factor matching — contact our technical team for confirmation.
Q: What does the “CN” suffix indicate?
A: The CN suffix designates a China-region or special-configuration variant. Electrically and mechanically it is equivalent to the standard -02 configuration; confirm with your system integrator for any regional certification requirements.
Q: Can this transducer measure axial position as well as radial vibration?
A: Yes. With appropriate mounting (thrust collar target), the 330103 probe can measure axial shaft position. Consult Bently Nevada installation guidelines for axial measurement setup.
Q: What is the minimum order quantity?
A: Single units are available. Volume pricing is available for orders of 5 units or more.
Q: Do you provide calibration certificates?
A: Factory calibration data is available where provided by the OEM. Third-party calibration services can be arranged upon request.
