Bently Nevada 330104‑00‑03‑05‑02‑05 — Detailed Technical Overview

1. Product Introduction

The Bently Nevada 330104‑00‑03‑05‑02‑05 is a precision eddy current proximity sensor engineered for non‑contact measurement of shaft vibration and displacement in rotating machinery. It is part of the 3300 XL Proximitor Sensor Series, a family of sensors widely used in industrial condition monitoring and machine protection systems.

This particular configuration combines a 3 mm sensing gap (code “03”), a 5 m integral cable (code “05”), a robust 2‑pin ClickLoc industrial connector (code “02”), and an enhanced signal output option (code “05”). The selected sensing gap enables reliable measurement of small displacements, and the enhanced output configuration provides improved signal conditioning for downstream monitoring modules.

The sensor’s design focuses on delivering accurate, stable, and repeatable displacement and vibration measurements in harsh industrial environments. Its sealed housing and durable construction help ensure long operational life in applications where reliability and continuous monitoring are essential.
