Bently Nevada 330902-00-50-05-02-00 3300 NSv Proximity Probes

Overview

The Bently Nevada 330902‑00‑50‑05‑02‑00 is a compact NSv (Narrow Side‑view) proximity probe designed for small‑target and tight‑clearance installations. With its 1/4‑28 UNF threaded body and armored integral cable, it is ideal for centrifugal compressors, refrigeration compressors, and other machinery where standard 5 mm or 8 mm probes cannot be installed.

Functional Characteristics

This NSv probe is optimized for small‑diameter shafts (≤51 mm) and axial targets under 15 mm. Its enhanced side‑view performance enables accurate measurements in restricted mounting geometries where counterbore depth or side‑view clearance is limited.

The 330902‑00‑50‑05‑02‑00 includes a 0.5 m (20 in) armored integral cable, providing mechanical protection and 220 N (50 lb) pull strength. The miniature ClickLoc coaxial connector ensures secure, low‑resistance mating with NSv extension cables and NSv Proximitor sensors.

The probe delivers the standard NSv scale factor of 7.87 V/mm (200 mV/mil) and maintains excellent linearity across its shorter NSv linear range, making it suitable for radial vibration, axial position, Keyphasor, and zero‑speed measurements.
