Bently Nevada 330904-00-21-10-02-05/CN Proximity Probe – 3300 NSv Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft imbalance, bearing wear, or rotor rub can escalate within minutes into catastrophic equipment failure, unplanned downtime, and six-figure repair costs. In high-stakes environments such as gas turbines, steam turbines, compressors, and pumps, continuous shaft position and vibration data is not optional — it is the last line of defense between normal operation and disaster. The Bently Nevada 330904-00-21-10-02-05/CN proximity probe is the precision sensing element that makes that protection possible.
The 330904-00-21-10-02-05/CN is a member of the Bently Nevada 3300 NSv (Non-contacting Vibration) Series — one of the most widely deployed eddy-current proximity probe systems in global industrial automation. Engineered to deliver sub-micron resolution and exceptional linearity, this specific configuration (21 mm probe, 10 mm cable, 02 connector, 05 extension, CN region variant) is optimized for installations requiring compact probe geometry with reliable signal integrity across demanding thermal and chemical environments. It is fully compatible with the 3300 XL and 3300 NSv signal conditioning systems, making it a direct-fit replacement or new-installation choice for thousands of existing monitoring architectures worldwide.
