Why Engineers Specify This Model
- NSv (Non-Standard Voltage) Output – Delivers a wider output voltage swing, enabling higher resolution displacement measurement in demanding applications where standard ±24 V systems fall short.
- 3300 XL Platform Compatibility – Plug-and-play integration with Bently Nevada 3300 XL Proximitor® sensors and 3500 Series monitoring racks, minimizing engineering rework.
- Extended Temperature Range – Rated to +177°C, making it suitable for hot-section turbine bearing pedestals without additional thermal shielding.
- Integral 9 m Cable – Factory-terminated cable eliminates field splicing, reducing installation error and improving signal integrity in high-EMI environments.
- API 670 Alignment – Meets the measurement chain requirements of API 670 (5th Edition) for machinery protection systems in oil & gas facilities.
- Proven Field Reliability – The 3300 XL series has accumulated millions of operating hours across global power generation and hydrocarbon processing assets.

Application-Specific FAQ
Q: Is the 330901-00-09-70-02-05 compatible with the standard 3300 XL Proximitor® (330180-X1-00)?
A: No. The NSv variant requires the NSv-specific Proximitor® sensor (330180-X1-05). Mixing standard and NSv components will result in incorrect scale factor output and potential monitor alarms.
Q: Can this transducer be used for axial position (thrust) measurement?
A: Yes. With appropriate mounting hardware and a flat target surface, the 330901 series can measure axial shaft position. Confirm the linear range covers your expected thrust travel before installation.
Q: What is the maximum gap voltage at the 2.54 mm (100 mil) end of the linear range?
A: Approximately –18 VDC (NSv output). Verify your monitor’s input range accepts this level before commissioning.
Q: Is a hazardous-area (ATEX/IECEx) version available?
A: Yes. Bently Nevada offers ATEX-certified variants of the 3300 XL series. Contact us with your zone classification and gas group for the correct part number.
Q: Do you provide calibration certificates?
A: Calibration verification reports are available upon request for an additional fee. Full OEM factory calibration certificates can be arranged for new-surplus units.
