Bently Nevada 330850-51-00 Proximity Sensor

Overview

The Bently Nevada 330850-51-00 Proximity Sensor delivers precise vibration and position measurements for compact industrial machinery. The NSv architecture supports space‑restricted installations on compressors, refrigeration units, and process gas equipment. The sensor integrates with the 3300 Proximity Transducer System and supports upgrades from older 3300 RAM, 3000, and 7000 series platforms.

Structural Design

The 330850-51-00 features a thin housing that fits high‑density DIN‑rail layouts or traditional panel mounts. The strong RFI immunity protects the transducer from high‑frequency interference and maintains stable measurement accuracy in electrically noisy environments. The SpringLoc terminal strips enable fast wiring without specialized tools, improving installation efficiency and long‑term reliability.

The sensor supports a complete 50 mm transducer system that includes a probe, extension cable, and Proximitor Sensor. The design delivers a maximum linear range of 27.9 mm (1100 mils), making it suitable for large‑scale displacement measurements in steam turbine generators.
