Bently Nevada 330905-00-11-10-02-CN Proximity Probe – 3300 NSv Series
When a critical rotating machine loses its shaft vibration monitoring capability, the consequences are immediate and severe: undetected rotor imbalance, bearing wear, or shaft misalignment can escalate within minutes into catastrophic machinery failure, unplanned downtime, and six-figure repair costs. In high-stakes environments — gas turbines, steam turbines, compressors, and pumps — continuous, accurate proximity measurement is not optional. The Bently Nevada 330905-00-11-10-02-CN proximity probe is the precision front-end sensor that makes that protection possible.
The 330905-00-11-10-02-CN is an 8mm eddy-current proximity probe within Bently Nevada’s industry-defining 3300 NSv (Non-contacting Vibration) series. Engineered to work seamlessly with the 3300 XL driver/extension cable system, this probe delivers the sub-micron resolution and wide temperature tolerance demanded by API 670-compliant machinery protection systems worldwide. It is one of the most widely deployed proximity probes in petrochemical, power generation, and heavy industrial facilities globally.

Frequently Asked Questions
Q: Is the 330905-00-11-10-02-CN a direct replacement for older 3300 NSv probes?
A: Yes. It is backward-compatible with the 3300 XL driver system. Verify the cable length suffix (-10 = 1.0 m) and connector type (-CN) match your existing installation before ordering.
Q: What is the difference between the -CN and standard connectors?
A: The -CN suffix denotes a CN-type connector, commonly specified for installations in China and certain Asian markets. Electrically, performance is identical to the standard version.
Q: Can this probe be used in hazardous (Ex) areas?
A: The probe itself is passive. Intrinsic safety compliance depends on the driver and associated barrier used. Consult your system integrator and the applicable Ex certification documentation.
Q: Do you provide calibration certificates?
A: We can provide available factory calibration documentation. For site-specific calibration, we recommend using a Bently Nevada-certified service center.
Q: What is the minimum order quantity (MOQ)?
A: There is no minimum order quantity. We supply single units as well as bulk orders.
Q: How long does shipping take?
A: Typical international express delivery (DHL/FedEx) is 3–7 business days. Sea freight and economy air options are available for larger orders.
