Bently Nevada 330904-00-04-10-02-05/CN Eddy-Current 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 mechanical failure, unplanned downtime, and six-figure repair costs. In high-stakes environments such as gas turbines, steam turbines, compressors, and pumps, the proximity probe is not a peripheral sensor — it is the first line of defense that keeps your machinery protection system alive.
The Bently Nevada 330904-00-04-10-02-05/CN is a precision eddy-current proximity probe belonging to the globally trusted 3300 NSv (Non-Standard Voltage) Series. Engineered for demanding continuous-duty applications, this probe delivers sub-micron resolution shaft displacement measurements and integrates seamlessly into Bently Nevada’s 3300 XL and 3500 Series monitoring systems. As one of the most widely deployed proximity probe configurations in the global turbomachinery market, the 330904-00-04-10-02-05/CN represents the benchmark for reliability in API 670-compliant machinery protection installations.
