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

1. Product Introduction

The Bently Nevada 330104‑00‑03‑05‑02‑00 is an industrial-grade eddy current proximitor sensor designed for precise, non-contact measurement of shaft vibration and displacement. It is part of the 3300 XL Proximitor Sensor Series, a trusted family of sensors widely used in rotating machinery monitoring and protection systems.

This particular model features a 3 mm sensing gap (code “03”), a 5 m cable length (code “05”), a 2‑pin ClickLoc industrial connector (code “02”), and a standard output configuration (code “00”). The compact sensor head allows installation in tight or constrained spaces, while the moderate cable length suits standard machinery layouts where the sensor head is near the monitoring module.

The sensor employs eddy current technology, generating an analog voltage proportional to the distance between the sensor and the metallic shaft. This provides continuous, high-resolution measurements critical for vibration analysis, rotor positioning, and predictive maintenance. Its robust sealed housing ensures reliable performance in industrial environments with oil, dust, and vibration exposure.
