System Compatibility
The 330903-00-09-50-02-00 is designed to operate within the complete Bently Nevada 3300 XL NSv Proximity Transducer System, which includes:
- Transducer: 330903 series (this unit)
- Extension Cable: 330130 / 330180 series
- Proximitor® Sensor (Driver): 3300 XL 8 mm Proximitor (e.g., 330180-X1-00)
- Monitor: 3500/40M, 3500/42M, or compatible 3300 XL rack monitors
Ensure all system components share the same series designation and cable length configuration for correct gap voltage and scale factor.
Selection Guide
Use the table below to identify the correct part number suffix for your application:
- Cable Length: -00-05 = 5 m | -00-09 = 9 m | -00-30 = 30 m
- Linear Range: -50 = 50 mil standard range
- Connector Type: -02 = standard coaxial | -00 = no connector (bare lead)
- Approval Code: -00 = standard (non-hazardous) | consult factory for ATEX/IECEx
If your application requires a different cable length, temperature rating, or hazardous area certification, contact support@konmask.com for a tailored recommendation.

Replacement & Compatibility FAQ
Q: Can I use a 330903-00-05-50-02-00 (5 m) in place of the 9 m version?
A: Only if the total system cable length (transducer + extension) matches the Proximitor driver specification. Mismatched lengths affect gap voltage and scale factor.
Q: Is the 330903-00-09-50-02-00 compatible with older 3300 series monitors?
A: The 3300 XL NSv series is backward-compatible with most 3300 series monitors. Verify the monitor firmware version and input card type before installation.
Q: Can third-party equivalents (e.g., Epro, Metrix) replace this unit?
A: Electrically similar units may work, but OEM certification and API 670 compliance cannot be guaranteed. Always consult your machinery OEM or rotating equipment engineer.
Q: What is the lead time for the 330903-00-09-50-02-00?
A: Typically 1–5 business days for in-stock units. Contact us for current availability.
Q: Do you provide calibration certificates?
A: Factory calibration documentation is included where available. Third-party calibration can be arranged upon request.
