Why Engineers Specify This Model
- Proven 3300 NSv Platform – backward-compatible with existing 3300 Proximitor® drivers and 3500 rack systems, minimizing retrofit cost
- 5 mm Tip for Tight Clearances – ideal for small-bore bearing housings where standard 8 mm probes cannot be installed
- 24-Inch Extension – pre-terminated extension eliminates field splicing, reducing installation error and signal noise
- Armored Cable – withstands high-vibration, high-temperature, and chemically aggressive environments without signal degradation
- API 670 Compliant – meets the machinery protection standard required by EPC contractors and end-users in oil & gas
- Direct OEM Replacement – drop-in substitute for legacy 330903 series probes with no recalibration required
Complete System Bill of Materials
For a fully functional proximity measurement loop, the following components are required alongside the 330903-00-24-05-02-00:
- Proximitor® Driver / Oscillator-Demodulator – e.g., Bently Nevada 3300 XL 8mm or 3300 NSv Proximitor (matched to probe series)
- Interconnect Cable – field wiring from Proximitor output to monitoring rack (typically 3-conductor shielded)
- 3500 Monitoring Rack – e.g., Bently Nevada 3500/42M Proximitor® Monitor for API 670 protection
- Mounting Hardware – M8 probe holder, lock nut, and bracket (stainless steel recommended)
- Target Surface Preparation – smooth, concentric shaft surface per BN installation guidelines (Ra ≤ 0.8 µm)
Compliance & Industry Standards
- API 670 – Machinery Protection Systems (5th Edition)
- IEC 60068-2 – Environmental Testing (vibration, temperature, humidity)
- CE Marking – EMC Directive 2014/30/EU
- RoHS Compliant – Restriction of Hazardous Substances
- ISO 10816 / ISO 20816 – Mechanical vibration evaluation guidelines

Application-Specific FAQ
Q: Is the 330903-00-24-05-02-00 compatible with the Bently Nevada 3500 rack?
A: Yes. When paired with a compatible 3300 NSv Proximitor® driver, the output signal is fully compatible with 3500 series monitors including the 3500/42M and 3500/40M.
Q: What is the difference between the 330903 and 330730 series?
A: The 330903 uses a 5 mm tip diameter (vs. 8 mm for 330730), making it suitable for smaller shaft diameters and tighter installation envelopes. Sensitivity and output range are equivalent when used with the correct Proximitor.
Q: Can this probe be used on non-ferrous shafts (e.g., titanium or Inconel)?
A: Eddy-current probes are sensitive to target material conductivity and permeability. Non-standard target materials require a system calibration using the actual shaft material. Contact Konmask for application-specific guidance.
Q: What is the maximum continuous operating temperature?
A: The probe tip is rated to +177 °C. The extension cable and connector are rated to +121 °C. For higher ambient temperatures, consult Bently Nevada’s high-temperature probe options.
Q: Do you provide calibration certificates?
A: Factory calibration data is available for new OEM units. For surplus units, functional test reports are provided. Third-party NIST-traceable calibration can be arranged on request.
