Product Description
Bently Nevada 330106-05-30-10-02-CN Proximity Probe: Industrial-Grade System Stability
The Bently Nevada 330106-05-30-10-02-CN is an original OEM proximity probe engineered for the 3300 XL Series continuous monitoring platform. Designed for mission-critical rotating machinery — including turbines, compressors, pumps, and gearboxes — this probe delivers precise non-contact displacement measurement to protect your assets from catastrophic failure. Whether you are performing a scheduled overhaul or responding to an unplanned shutdown, sourcing a verified original spare is the single most important decision in your maintenance workflow.
Built to exacting Bently Nevada tolerances, the 330106-05-30-10-02-CN features a 5 mm tip diameter, 30 cm armored cable, and a CN-standard connector interface — making it a direct drop-in replacement for aging or damaged probes in existing 3300 XL installations without recalibration of the monitor rack.

Preventive Maintenance Strategy
A proximity probe replacement is never an isolated event — it is an opportunity to audit the entire eddy-current measurement chain. During the installation of the 330106-05-30-10-02-CN, your maintenance team should systematically inspect every component that shares signal integrity with this probe.
Begin with the extension cable. A degraded or kinked cable introduces signal noise that can trigger false alarms or, worse, mask genuine vibration events. We strongly recommend verifying the condition of the Bently Nevada 330130-040-03-CN Extension Cable (3300 XL, 4m Armored) — the factory-matched companion cable for this probe series.
Next, inspect the interconnect cabling between the probe and the monitor rack. Shielding integrity is critical in high-EMI environments such as motor control rooms. The Bently Nevada 16710-08 Interconnect Cable (3300 Series, 8ft Shielded) and the Bently Nevada 16710-15 Armored Interconnect Cable (15ft, 3-Conductor) are the recommended replacements for standard and heavy-duty runs respectively.
For longer cable runs in large turbine halls, the Bently Nevada 16710-25 Interconnect Cable (25ft) and the Bently Nevada 16710-99 Armored Interconnect Cable (99ft, Heavy-Duty) provide the reach and shielding required without signal attenuation.
At the monitor rack level, confirm that the Bently Nevada 1900/27 Vibration Monitor (Single-Channel, 24VDC) is operating within its calibrated range. A probe in perfect condition paired with a drifted monitor will still produce unreliable readings. Simultaneously, verify the grounding integrity of the rack via the Bently Nevada 138257-01 Earthing Module (3500/04) — improper grounding is the leading cause of unexplained noise in eddy-current systems.
Finally, if your installation includes a reverse-mount configuration or a confined bearing housing, consider stocking the Bently Nevada 330907 3300 NSv Reverse Mount Probe (M10×1, 5m) as a parallel spare to cover alternative probe geometries on the same machine train.
Strategic Replacement Solutions
The 330106-05-30-10-02-CN is the designated replacement for legacy Bently Nevada 330106 series probes installed prior to the 3300 XL platform upgrade cycle. It maintains full backward compatibility with existing proximitor/oscillator drivers and does not require changes to monitor rack configuration, alarm setpoints, or gap voltage references — reducing replacement downtime to under 30 minutes for a trained technician.
For facilities transitioning from older 3300 NSv installations, this probe can be integrated alongside the Bently Nevada 3500/22-01-01-01 TDI Module and I/O and the Bently Nevada 3500/33 16-Channel Relay Module to build a fully modernized, API 670-compliant monitoring architecture without replacing the entire rack infrastructure.
Support FAQ
Q: Does this probe carry a warranty?
A: Yes. All units ship with a 12-month warranty covering manufacturing defects and electrical performance. Warranty claims are processed within 5 business days.
Q: Is the 330106-05-30-10-02-CN still in production?
A: This part is available as a genuine OEM spare. Lead times vary by stock level — contact us for real-time availability before scheduling your maintenance window.
Q: Can this probe be used with non-Bently Nevada drivers?
A: The 330106 series is optimized for use with Bently Nevada proximitor drivers. Use with third-party drivers may affect linearity and is not covered under warranty.
Q: What is the expected service life of this probe?
A: Under normal operating conditions (within rated temperature and gap range), the 330106-05-30-10-02-CN has a design life exceeding 10 years. Annual gap voltage verification is recommended as part of your PM schedule.
Q: Do you provide calibration certificates?
A: Factory calibration documentation is available upon request. Please specify your requirement at the time of order.
Q: What is your lead time for this part?
A: In-stock units ship within 2–5 business days internationally. Express shipping options are available for emergency shutdowns.
