The Bently Nevada 330980-51-CN is part of the 3300 XL NSv (Narrow Side-view) Proximity Transducer System, specifically designed for machinery with limited installation space. The “NSv” system combines advanced eddy current sensing technology with a compact design to deliver accurate, real-time vibration and displacement monitoring in challenging industrial environments.
The “-51” designates a system length of 5.0 meters, and the “-CN” suffix typically represents compliance with Chinese certification standards or region-specific adjustments, ensuring compatibility with Chinese industrial systems.
The 330980-51-CN system includes:
An 8 mm NSv proximity probe
Extension cable
NSv Proximitor Sensor module
Monitoring small steam turbines
Gearboxes in confined installation zones
Compressors and small-scale rotating equipment
Electric motors with tight radial clearance
Vibration detection in power generation, oil & gas, petrochemical, and manufacturing
β Compact Form Factor β Ideal for narrow mounting locations
β Precise Measurement β Highly accurate readings for small shaft diameters
β High Temperature Tolerance β Designed for industrial thermal conditions
β Vibration Resistance β Durable under continuous machine operation
β Quick Integration β Seamless with 3300/3500 Monitoring Systems
β Certified for Chinese Markets β Meets regional compliance standards
β Stable Output β Low sensitivity to power fluctuations
β Modular Design β Easy replacement and maintenance
