The Bently Nevada 330104-06-14-50-02-00 is a precision proximity probe designed for continuous condition monitoring of critical rotating machinery. It provides accurate AC voltage output for measuring shaft displacement and vibration, fully compatible with the 3300 series machinery protection system.
This probe is built to endure harsh industrial environments, including high temperatures, dust, and vibration. Its robust stainless steel tip and reinforced housing ensure long-term durability. The device supports predictive maintenance by detecting rotor misalignment, bearing wear, and imbalance early, helping prevent unplanned downtime.
The “50” in the model indicates a specialized configuration optimized for higher stability under moderate temperature fluctuations and mechanical stress.
