Where This Product Is Used
The Bently Nevada 330904-00-24-05-01-00 is a high-precision proximity transducer system engineered for continuous shaft vibration and position monitoring in rotating machinery. It is widely deployed in:
- Steam & Gas Turbines – Real-time radial vibration measurement on HP/LP rotor shafts in power generation plants
- Centrifugal Compressors – Shaft displacement monitoring in oil & gas upstream and midstream compression trains
- Pumps & Blowers – Continuous bearing journal orbit tracking in petrochemical process units
- Gearboxes & Expanders – Axial position and differential expansion measurement in refinery and LNG facilities
- Marine Propulsion Systems – Shaft eccentricity monitoring on large diesel and gas turbine drives
Wherever API 670 machinery protection is mandated, the 3300 XL NSv system is the engineer-specified solution.

Why Engineers Specify This Model
- NSv Output Compatibility – The Non-Standard Voltage output integrates directly with legacy 3300 series monitors without recalibration, protecting existing infrastructure investment
- Plug-and-Play System – Probe, extension cable, and driver are factory-matched and calibrated as a complete system, eliminating field calibration errors
- High-Temperature Probe – Rated to 177°C, suitable for hot-section turbine bearing housings without additional thermal isolation
- Wide Frequency Bandwidth – DC to 10 kHz response captures both slow-roll runout and high-frequency sub-synchronous instabilities
- API 670 Compliant – Meets the 5th Edition standard for machinery protection systems, satisfying insurance and regulatory requirements
- Proven Field Reliability – 3300 XL platform has accumulated millions of operating hours across global power, oil & gas, and petrochemical installations

Application-Specific FAQ
Q: Is the 330904-00-24-05-01-00 compatible with the Bently Nevada 3500 rack?
A: Yes. The NSv driver output is compatible with 3500/40M and 3500/42M Proximitor I/O modules when configured for NSv input range. Verify rack firmware version ≥ 4.x.
Q: Can this system monitor axial position as well as radial vibration?
A: Yes. With appropriate mounting geometry (thrust collar target), the same transducer system measures axial shaft position. Consult Bently Nevada application note AN-028 for installation guidance.
Q: What shaft materials are compatible?
A: Standard calibration is for AISI 4140 steel. For Inconel, titanium, or other alloys, a material-specific calibration curve is required. Contact us for alloy-specific system options.
Q: Does the system require field calibration after installation?
A: No. The 330904-00-24-05-01-00 is factory-calibrated as a matched system. Field verification of gap voltage at the nominal air gap (50 mil / 1.27 mm = –9 VDC) is recommended per API 670 commissioning procedures.
Q: What is the difference between the standard 3300 XL and the NSv variant?
A: The NSv (Non-Standard Voltage) variant operates at –18 VDC supply instead of the standard –24 VDC, enabling direct retrofit into older 3300 series monitor racks without power supply modification.
