Bently Nevada 330910-00-21-10-02-00 Proximity Probe – 3300 NSv Series
When a critical rotating machine loses its vibration monitoring signal, the consequences are immediate and severe: undetected shaft imbalance, bearing wear, or rotor rub can escalate within seconds into catastrophic equipment failure, unplanned downtime, and six-figure repair costs. In high-stakes environments — power generation turbines, petrochemical compressors, and marine propulsion systems — the proximity probe is not a peripheral sensor; it is the first line of defense for machine health. Without a reliable, OEM-compatible probe in place, your entire condition monitoring system is blind.
The Bently Nevada 330910-00-21-10-02-00 is an 8mm eddy-current proximity probe engineered for the 3300 NSv (Non-contact Shaft Vibration) monitoring system — one of the most widely deployed machinery protection platforms in global industrial automation. Within the 3300 NSv ecosystem, this probe model occupies the standard-range, general-purpose position: a 200 mil (5.08 mm) linear measurement range, 5-meter integral cable, and a -24 VDC bias voltage output that interfaces directly with 3300 NSv proximitor/seismometer modules. It is the go-to replacement probe for OEM-installed systems across refineries, LNG terminals, and utility power plants worldwide.
