Bently Nevada 330905-00-10-05-02-CN NSv Proximity Probe

Description

The Bently Nevada 330905-00-10-05-02-CN is a compact NSv proximity probe designed for accurate non-contact shaft vibration and position measurement in small and medium rotating machines. It offers stable eddy-current sensing performance in confined installation spaces where standard 8 mm probes cannot fit. Engineers rely on this probe for precise shaft behavior monitoring in pumps, compressors, motors, and gear-driven equipment. Moreover, its rugged stainless-steel housing and high-temperature cable construction ensure dependable operation in harsh industrial environments. The China-specific “CN” variant supports regional compliance requirements while maintaining full system compatibility. Therefore, the probe integrates naturally into the 3300 NSv Proximity Transducer System without requiring field recalibration.

Typical Applications

The 330905-00-10-05-02-CN is widely used in compact machinery where engineers must monitor tightly confined rotating components. For instance, small multistage pumps, gearboxes, and industrial motors benefit from its accurate displacement measurement. In addition, the probe fits easily into OEM equipment due to its short threaded section and narrow profile. Many operators deploy it in condition monitoring programs to track shaft displacement trends and prevent unplanned downtime.

Support & Reliability

The probe offers long operational life with minimal maintenance because it avoids mechanical wear. Moreover, its modular NSv system design allows fast field replacement of the probe, extension cable, or Proximitor without recalibration. This modularity improves service efficiency and ensures consistent system accuracy.
