Bently Nevada 330104‑00‑03‑50‑02‑00 — Detailed Technical Overview

1. Product Introduction

The Bently Nevada 330104‑00‑03‑50‑02‑00 is an industrial eddy‑current proximity transducer designed for non‑contact measurement of vibration and shaft displacement in large rotating machinery. It belongs to the 3300 XL Proximitor Sensor Series, a well‑established product family used for continuous condition monitoring, machinery protection, and predictive maintenance in demanding industrial environments.

This model is configured with a 3 mm sensing gap (code “03”), a 50 m integral cable (code “50”), and a robust 2‑pin ClickLoc industrial connector (code “02”), with a standard analog output (code “00”). The extended 50 m cable enables the sensor head to be installed at a significant distance from monitoring modules — an important requirement in large turbine halls, compressor stations, or plants with constrained equipment spacing.

The proximitor sensor uses eddy‑current technology, which generates an electromagnetic field at the sensor tip. As a conductive target — typically the rotating shaft — moves into or out of this field, changes in the field are converted to a proportional analog voltage. This output is used by monitoring systems to detect displacement, vibration trends, shaft position, and early warning signs of mechanical failures.
