Bently Nevada 330104‑00‑04‑05‑02‑CN — Detailed Technical Overview

1. Product Introduction

The Bently Nevada 330104‑00‑04‑05‑02‑CN is an industrial eddy‑current proximitor sensor designed for accurate, non‑contact monitoring of shaft vibration and displacement in rotating machinery. It is part of the 3300 XL Proximitor Sensor Series, which has been widely deployed in critical machinery protection and condition monitoring applications for decades.

The “CN” designation typically indicates a customized or regional version for installations requiring specific configuration or certification. This sensor features a 4 mm sensing gap, a 5 m integral cable, and a 2‑pin ClickLoc industrial connector, producing a standard analog output compatible with 3300 XL monitoring modules or other analog acquisition systems.

Eddy‑current technology allows the sensor to detect small changes in magnetic flux caused by the proximity of a rotating shaft and converts these changes into proportional voltage signals. This enables precise tracking of vibration levels, shaft displacement, and early detection of mechanical issues such as imbalance, misalignment, or bearing wear.
