Bently Nevada 330104‑00‑02‑50‑02‑05 — Detailed Technical Overview

1. Product Introduction

The Bently Nevada 330104‑00‑02‑50‑02‑05 is a high‑precision industrial proximitor sensor specifically designed for non‑contact measurement of shaft vibration and displacement in rotating machinery. This model is part of the 3300 XL Proximitor Sensor Series, a mature and widely adopted family of sensors used in condition monitoring and machine protection.

This configuration combines a small 2 mm sensing gap (code “02”) with a long 50 m integral cable (code “50”), a rugged 2‑pin ClickLoc industrial connector (code “02”), and an enhanced output option (code “05”) for improved signal conditioning. The extended cable allows flexible placement of the sensor head relative to the monitoring system, while the enhanced output configuration supports robust interfacing with downstream monitoring modules.

The proximitor sensor uses eddy current technology to detect changes in the magnetic field caused by the proximity of a metallic surface. As the shaft moves closer or further from the sensor, changes in the field are translated into an analog voltage signal proportional to displacement. This enables precise real‑time monitoring of vibration and position, which is critical for protecting machinery health and avoiding catastrophic failures.
