Bently Nevada 330171-00-12-10-02-00 Eddy-Current Proximity Probe – 3300 XL 8mm Transducer System
When a critical rotating machine — a steam turbine, centrifugal compressor, or large induction motor — loses its shaft vibration monitoring capability, the consequences are immediate and severe. Without a functioning proximity probe, operators are blind to radial shaft displacement, oil-whirl instability, and rub events that can escalate from a minor anomaly to a catastrophic bearing failure within seconds. Unplanned downtime in heavy industry routinely costs tens of thousands of dollars per hour, and the loss of a single proximity probe in a redundant monitoring loop can trigger a mandatory plant shutdown under API 670 safety protocols.
The Bently Nevada 330171-00-12-10-02-00 is an 8mm eddy-current proximity probe engineered for the 3300 XL Proximity Transducer System — one of the most widely deployed machinery protection platforms in the global oil & gas, power generation, and petrochemical industries. Within the 3300 XL family, this specific configuration (12-inch armored cable, 10-32 UNF tip thread, 2-meter extension cable, standard driver) occupies the core position: it delivers the precision and environmental robustness demanded by API 670 fourth-edition installations while maintaining backward compatibility with legacy 3300 series monitor racks. Its global installed base spans refineries in the Middle East, LNG terminals in Southeast Asia, and power plants across Europe and North America.
