Why Choose the Original Model
- Factory-calibrated sensitivity matched to Bently Nevada 3300 drivers and monitors
- NSV design eliminates interference in high-noise electrical environments
- API 670 compliant — meets machinery protection standards for turbines, compressors, and pumps
- Proven reliability in petrochemical, power generation, and LNG plant environments
- Seamless integration with existing 3300 XL extension cables and proximitor/oscillator drivers
Typical Applications
- Radial shaft vibration monitoring on steam and gas turbines
- Axial position measurement on centrifugal compressors
- Differential expansion monitoring in power plant turbines
- Eccentricity measurement on large rotating shafts
- Speed and phase reference (Keyphasor) in conjunction with 3300 monitors
System Compatibility
- Monitors: Bently Nevada 3300/16, 3300/20, 3500/42, 3500/45
- Drivers (Proximitors): 330180, 330185 NSV Proximitor
- Extension Cables: 330130 series (matched to 2.0 m probe cable for standard 5 m or 9 m total)
- DCS Integration: Compatible with Emerson DeltaV, Honeywell Experion, ABB 800xA via 4–20 mA or digital output from monitor
Selection Guide
Use the following criteria to confirm the correct probe for your application:
- Tip diameter: 8 mm suits shaft diameters 25–100 mm; use 5 mm probes for smaller shafts
- Cable length: 330909-00-20-10-01-05 = 2.0 m integral cable; match to your extension cable for total system length (5 m or 9 m)
- Voltage standard: NSV (Non-Standard Voltage) — confirm your proximitor is NSV-rated (330185); do not mix with standard 330180 without recalibration
- Environment: Standard housing suits most industrial environments; specify armored cable (-02-) for high-vibration conduit routing
- Certification: Confirm ATEX/IECEx requirements if installing in hazardous areas — contact us for certified variants

Replacement & Compatibility FAQ
Q: Can I use a 3300 XL 330905 probe as a direct replacement?
A: The 330905 is a standard-voltage probe. It is physically similar but requires a standard 330180 proximitor, not the NSV 330185. Mixing these without recalibration will produce incorrect gap voltage readings.
Q: Is the PR6423/010-030 (Epro) a true drop-in replacement?
A: Functionally yes for most 3300 monitor inputs, but sensitivity calibration should be verified. Contact us for a compatibility checklist.
Q: What is the difference between -01- and -02- in the part number?
A: The -01- denotes a standard PVC-jacketed cable; -02- denotes an armored (stainless braid) cable for mechanical protection in conduit installations.
Q: Do you supply ATEX-certified versions?
A: Yes. Please specify your hazardous area classification (Zone 1/2, Group IIC, etc.) when requesting a quote.
Q: Can Konmask.com provide calibration certificates?
A: Yes, factory calibration certificates are available for new units. Third-party calibration reports can be arranged on request.
