System Compatibility
The 330905-00-12-05-02-05 probe is designed to operate within the Bently Nevada 3300 XL NSv system, which includes:
- Extension cables: 330130-XX-XX (matched to probe cable length)
- Drivers / Oscillator-Demodulators: 3300 XL 8mm proximitor (e.g., 330180-X1-CN)
- Monitoring systems: 3500 Series, System 1 Evolution, Orbit 60
- Total system cable length: 5 m probe + extension = system-specific (typically 9 m or 15 m total)
Note: NSv probes are NOT interchangeable with standard 3300 XL probes without driver replacement.
Selection Guide
Use the part number decoder below to select the correct variant for your application:
330905 - 00 - 12 - 05 - 02 - 05 │ │ │ │ │ └─ Cable armor: 05 = armored, 00 = unarmored │ │ │ │ └───── Connector: 02 = standard BNC │ │ │ └────────── Cable length: 05 = 5 m │ │ └─────────────── Probe body length: 12 = 12 mm │ └──────────────────── Revision: 00 └───────────────────────────── Series: NSv 8mm proximity probe
Key selection criteria:
- Cable length: Must match or be combined with extension cable to reach the proximitor. Common lengths: 5 m, 9 m, 10 m.
- Armor requirement: Specify suffix -05 for armored cable in high-vibration or high-temperature areas.
- Driver compatibility: Confirm your proximitor is rated for NSv probes (not standard 3300 XL).
- Thread/mounting: M10 × 1 standard; verify bracket compatibility before ordering.

Replacement & Compatibility FAQ
Q: Can I use a standard 3300 XL 8mm probe instead of the NSv version?
A: No. NSv probes use a different sensitivity curve and require NSv-compatible proximitor drivers. Substituting a standard probe will result in incorrect readings and may trigger false alarms.
Q: What is the difference between suffix -02-05 and -02-00?
A: The last two digits indicate cable armor. -05 = armored (stainless steel braid), -00 = unarmored. Choose armored for environments with mechanical abrasion or high EMI.
Q: Can I extend the probe cable with a standard extension cable?
A: Yes, using Bently Nevada 330130-series extension cables. Total system cable length must match the proximitor’s calibrated range (typically 9 m or 15 m).
Q: Is this probe suitable for ATEX Zone 1 hazardous areas?
A: Consult the specific ATEX certificate for this part number. Bently Nevada offers ATEX-certified variants; verify the suffix and certificate before installation.
Q: Do you provide calibration certificates?
A: OEM calibration documentation is included with genuine parts. Third-party calibration services can be arranged upon request.
