Why Engineers Specify This Model
- NSv Designation: Non-Standard voltage output allows integration with legacy DCS/PLC systems that cannot accept standard ±24 VDC driver supply, reducing retrofit costs.
- 3300 XL Platform Compatibility: Fully interchangeable within the Bently Nevada 3300 XL ecosystem — no recalibration required when replacing worn probes.
- High-Temperature Resilience: Rated to 177°C, suitable for hot-section turbine bearing pedestals without additional thermal shielding.
- API 670 Alignment: Meets the measurement chain requirements for radial vibration, axial position, and differential expansion per API 670 5th Edition.
- Minimal Maintenance: Non-contact sensing eliminates mechanical wear; MTBF exceeds 100,000 hours in clean environments.

Application-Specific FAQ
Q: Is the 330909-10-99-10-11-CN a direct replacement for the standard 330909-10-99-10-00-CN?
A: The -11 suffix denotes the NSv (Non-Standard voltage) output configuration. It is physically identical but electrically incompatible with standard-voltage drivers. Always verify driver compatibility before substitution.
Q: Can this probe be used with a 3500/42M monitor without modification?
A: Yes, provided the corresponding NSv Proximitor driver is installed. The 3500/42M accepts the NSv signal chain natively when configured correctly in the rack software.
Q: What is the recommended gap voltage for this probe on AISI 4140 steel?
A: The nominal gap is set to achieve –10 VDC output (approximately 50 mil / 1.27 mm gap) for standard radial vibration monitoring per Bently Nevada calibration curves.
Q: Does Konmask provide installation support?
A: We provide technical documentation, wiring diagrams, and remote commissioning guidance. On-site support can be arranged through our partner network — contact us for details.
Q: Is this part available with ATEX certification for hazardous areas?
A: The -CN suffix indicates a China-market configuration. For ATEX/IECEx-rated variants, please contact us with your zone classification and we will source the appropriate certified assembly.
