System Compatibility
The 330905-00-05-05-05-02-05 probe is designed to operate with the following Bently Nevada systems:
- 3300 NSv Proximitor® / Seismic Monitor
- 3300 XL 8mm Proximitor® Sensor
- System 1® Condition Monitoring Software (data acquisition)
- 3500 Series Machinery Protection System (with appropriate proximitor)
- ADRE® 408 DSPi Data Acquisition System
For non-Bently Nevada monitor systems, consult the driver input impedance and bias voltage specifications before installation.
Selection Guide
Use the following criteria to confirm the 330905-00-05-05-05-02-05 is the correct probe for your application, or to identify the best alternative:
- Tip diameter: 5 mm — suitable for shaft diameters ≥ 25 mm; use 8 mm probes for larger shafts.
- Cable length: 5 m standard — extension cables available for longer runs (max 9 m total system cable).
- Target material: Optimized for AISI 4140 / 4340 steel; stainless or non-ferrous targets require recalibration.
- Temperature: Up to +177 °C probe body; select high-temp cable jacket for ambient > 120 °C.
- Driver pairing: Must use with 3300 NSv or XL Proximitor®; incompatible with 7200 or 3000 series drivers.
- Mounting thread: M8 × 1.0 — verify bracket thread before ordering.
Quality Assurance & Sourcing
- All units sourced from authorized distributors or verified surplus channels.
- Each probe undergoes incoming inspection: visual check, connector integrity, and dimensional verification.
- Traceability documentation (CoC / test reports) available upon request.
- Konmask specializes in current-production and legacy Bently Nevada inventory for MRO and capital projects.

Replacement & Compatibility FAQ
Q: Can I use a 330905-00-05-05-05-02-05 with a 3500 Series monitor?
A: Not directly. The 3500 system requires its own proximitor. However, the probe can be used with a 3300 NSv Proximitor® feeding a 3500 monitor input.
Q: What is the difference between 330905 and 330900 series probes?
A: The 330905 (NSv) features improved EMI shielding and a revised connector design vs. the legacy 330900 (XL). Both share the same sensitivity and gap range.
Q: Is an Epro PR6423 a direct drop-in replacement?
A: Functionally similar, but the PR6423 uses an 8 mm tip and different driver electronics. It is not a direct drop-in — driver and bracket changes are required.
Q: Do you supply calibration certificates?
A: Yes. Factory calibration data and CoC are available for new units. Contact us before ordering if documentation is required.
Q: Can I order a custom cable length?
A: Standard lengths are 1 m, 3 m, 5 m, and 9 m. Custom lengths are available via special order — lead time applies.
