Why Engineers Specify This Model
- API 670 Compliance — meets the 5th Edition standard for machinery protection instrumentation, required for critical rotating equipment in oil & gas
- 3300 XL Eddy-Current Technology — superior immunity to electrical runout and target material variation compared to earlier 3300 series probes
- Plug-and-Play with 3500 Rack — pre-calibrated to work directly with Bently Nevada 3500/40M, 3500/42M, and 3500/45 monitor modules without field calibration
- Hazardous Area Rated — FM/CSA Division 1 and ATEX Zone 1 certified for use in explosive atmospheres common in refineries and offshore platforms
- Long-Term Stability — armored cable construction and hermetically sealed probe tip ensure reliable performance in high-vibration, high-temperature environments
- Dual-Use Capability — measures both radial vibration (dynamic) and shaft centerline position (static DC gap) simultaneously from a single installation point

Application-Specific FAQ
Q: Is the 330903-00-23-10-01-00 compatible with older Bently Nevada 3300 series monitors?
A: The 3300 XL probe is backward-compatible with most 3300 series Proximitor monitors. However, for new installations, Bently Nevada recommends pairing with the 3500 series rack for full API 670 compliance and System 1 integration.
Q: Can this transducer be used on non-steel targets such as titanium or Inconel shafts?
A: Yes, but a target-material-specific calibration curve must be applied. Contact Bently Nevada or Konmask.com for application-specific calibration data sheets.
Q: What is the maximum shaft speed this system can monitor?
A: The 3300 XL system supports frequency response up to 10,000 Hz (–3 dB), suitable for shaft speeds up to approximately 600,000 RPM in keyphasor applications, and standard vibration monitoring up to 60,000 RPM.
Q: Does the 330903-00-23-10-01-00 include the Proximitor driver/oscillator?
A: Yes. The 330903 part number designates a complete proximity transducer system including probe, extension cable, and integral Proximitor driver. No separate driver module is required.
Q: Is this part suitable for use in a SIL-rated safety instrumented function?
A: The 3300 XL series has been assessed for use in SIL 1 and SIL 2 loops per IEC 61511 when installed per Bently Nevada’s functional safety manual. Contact us for the relevant SIL data package.
