Compatible Replacement & Equivalent Models
The table below lists direct replacements and functional equivalents for the 330901-10-20-10-02-05. Always verify cable length, sensitivity, and driver compatibility before substitution.
- 330901-10-20-10-02-00 — Same probe/driver, standard temperature range (drop-in replacement for most applications)
- 330901-10-20-10-02-CN — China-market variant, identical electrical specs
- 330780-90-00 — 3300 XL 8 mm standard proximity transducer (non-NSv); compatible with 3300 XL monitors when NSv is not required
- 330730-040-00-CN — 3300 XL 5 mm probe; suitable for tighter installation clearances
- Emerson CSI 330901 series — Post-acquisition equivalent, same form/fit/function
- Epro PR6423 series — Third-party eddy-current equivalent; verify monitor compatibility
- Metrix ST5484E — Alternative brand proximity system; requires signal conditioning check
⚠ Note: NSv (Non-Standard voltage) probes require NSv-compatible Proximitor drivers. Do not mix standard and NSv components.
Why Choose the Original Model
- Factory Calibration: Each system is calibrated as a matched set (probe + cable + proximitor) for guaranteed accuracy.
- API 670 Compliance: Meets the industry standard for machinery protection systems.
- Long-Term Support: Bently Nevada provides firmware, documentation, and spare parts continuity.
- Hazardous Area Certification: FM/CSA approved for use in explosive atmospheres.
- Proven Reliability: Deployed globally in power generation, oil & gas, and petrochemical plants.
Typical Applications
- Radial shaft vibration monitoring on steam and gas turbines
- Axial position (thrust) measurement on compressors
- Differential expansion monitoring on large rotating machinery
- Speed and phase reference (Keyphasor) measurement
- Eccentricity monitoring during slow-roll startup
- Integration with Bently Nevada 3500 / 3300 series monitoring racks
System Compatibility
- Monitor Racks: Bently Nevada 3500 Series, 3300 Series, System 1 software
- DCS Integration: Compatible with Emerson DeltaV, Honeywell Experion, ABB 800xA via 4–20 mA or digital outputs
- Proximitor Driver: Must use 3300 XL NSv 8 mm Proximitor (e.g., 330180-91-00) — standard Proximitors are NOT compatible
- Cable Extension: Use only Bently Nevada matched extension cables to preserve calibration
- Target Gap: Recommended installation gap 1.0 mm (40 mil) for optimal linearity
Selection Guide
Use the following decision matrix to select the correct 330901 variant for your application:
- Standard temperature + standard voltage → 330780-90-00 or 330901-10-20-10-02-00
- High-temperature environment (>100°C) → 330901-10-20-10-02-05 (this model, rated to 121°C)
- Tight radial clearance (<8 mm probe OD) → 330730 series (5 mm probe)
- Hazardous area (Zone 1 / Div 1) → Confirm FM/CSA approval on selected part suffix
- Retrofit to non-Bently monitor → Contact Konmask for signal conditioning options
- Budget-sensitive replacement → Epro PR6423 or Metrix ST5484E (verify compatibility first)

Replacement & Compatibility FAQ
Q: Can I use a standard 3300 XL Proximitor with the 330901-10-20-10-02-05 probe?
A: No. The NSv probe requires an NSv-compatible Proximitor. Using a standard driver will result in incorrect output and potential damage.
Q: Is the 330901-10-20-10-02-05 a drop-in replacement for the -02-00 suffix?
A: Yes, electrically identical. The -05 suffix indicates an extended temperature rating. It is backward compatible in standard-temperature installations.
Q: Can Epro PR6423 replace this unit in a Bently Nevada 3500 rack?
A: Epro probes can be used with appropriate signal conditioning, but are not plug-and-play in a 3500 rack without additional configuration. Contact us for details.
Q: What is the lead time for the 330901-10-20-10-02-05?
A: Typically 3–7 business days for in-stock units; 4–8 weeks for factory order. Contact us for current availability.
Q: Do you provide calibration certificates?
A: Yes. Factory calibration data sheets are available. Third-party recalibration can be arranged upon request.
