Bently Nevada 330904-00-16-50-02-00 – Non-Contact Shaft Vibration Transducer | 3300 XL NSv Platform
Engineering Background: The Bently Nevada 3300 XL NSv (Non-Standard Voltage) Proximity Transducer System is engineered for continuous, non-contact measurement of radial shaft vibration, axial position, and differential expansion in rotating machinery. Developed under GE’s precision instrumentation heritage, this system is the field-proven standard for turbomachinery protection in power generation, petrochemical, and heavy industrial environments.
Product Positioning: Part number 330904-00-16-50-02-00 is a complete proximity transducer assembly configured for 16 mm probe tip diameter, 5.0 m (50 dm) extension cable, and 2.0 m (20 dm) driver cable — optimized for API 670-compliant machinery protection systems. This unit integrates directly with Bently Nevada 3300 series monitors and 3500 rack systems.

System Architecture & Signal Flow
The 330904-00-16-50-02-00 operates as a three-component eddy-current system:
- Probe (330904 series): Generates a high-frequency electromagnetic field; detects gap change as shaft displacement.
- Extension Cable (50 dm): Transmits the RF signal from probe tip to driver with minimal loss; armored for mechanical protection.
- Driver / Oscillator-Demodulator (2.0 m cable): Converts RF impedance variation into a calibrated DC voltage output (–18 VDC nominal at mid-gap).
Output feeds directly into Bently Nevada 3300 XL monitor input cards or 3500/40M Proximitor I/O modules for real-time vibration and position alarming.

Technical FAQ
Q: Is the 330904-00-16-50-02-00 compatible with the Bently Nevada 3500/40M monitor?
A: Yes. The NSv output is directly compatible with 3500/40M Proximitor input channels. Verify channel configuration for –18 VDC bias range.
Q: Can this transducer be used on non-ferrous targets (e.g., titanium, Inconel)?
A: Yes, with a target-specific calibration curve. Contact our engineering team for calibration data for your specific alloy.
Q: What is the maximum gap for reliable measurement?
A: The linear range is 0.25 – 2.25 mm. For API 670 applications, the recommended operating gap is 1.0 – 1.5 mm (40 – 60 mil).
Q: Is a calibration certificate included?
A: A certificate of conformance is available on request. NIST-traceable calibration reports can be arranged for an additional fee.
Q: What is the lead time for bulk orders (>10 units)?
A: Typically 3–7 business days for stock items. Contact us for volume pricing and expedited options.
