Where This Product Is Used
The Bently Nevada 330903-00-17-50-02-00 is a precision eddy-current proximity transducer system engineered for continuous, non-contact measurement of shaft vibration, position, and differential expansion in critical rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines — radial shaft vibration and axial position monitoring per API 670
- Centrifugal & Axial Compressors — real-time rotor dynamic surveillance in petrochemical and LNG plants
- Pumps & Fans — bearing journal orbit analysis in power generation and water treatment facilities
- Gearboxes & Expanders — high-speed shaft tracking in refinery and upstream oil & gas applications
- Marine Propulsion Systems — shaft displacement monitoring in shipboard turbomachinery

Application-Specific FAQ
Q: Is the 330903-00-17-50-02-00 compatible with the Bently Nevada 3500 rack?
A: The NSv output (–24 VDC) is designed for 3300 series monitors. For 3500 racks, verify the Proximitor® driver compatibility or specify the standard –18 VDC variant (330903-00-17-50-01-00).
Q: Can this transducer be used on non-conductive shafts?
A: No. Eddy-current proximity transducers require an electrically conductive target material (typically steel or Inconel). For non-conductive targets, a laser or capacitive displacement sensor is required.
Q: What is the maximum shaft speed this system can measure?
A: The 3300 XL system supports frequency response up to 10,000 Hz, making it suitable for machinery operating up to 600,000 RPM in theory; practical limits are set by the monitor’s input bandwidth.
Q: Do you provide installation and commissioning support?
A: Konmask.com provides technical documentation and remote commissioning guidance. On-site services can be arranged through our partner network — contact us for details.
Q: Is a calibration certificate included?
A: A factory calibration record is available for new units. For surplus/refurbished stock, a third-party calibration certificate can be arranged upon request at additional cost.
