Bently Nevada 330104‑00‑02‑10‑02‑05 — Detailed Technical Overview
1. Product Introduction
The Bently Nevada 330104‑00‑02‑10‑02‑05 is a precision eddy current proximitor sensor designed for continuous monitoring of shaft vibration and displacement in industrial rotating machinery. It is part of the 3300 XL Proximitor Sensor Series, a proven family of non‑contact displacement sensors used in condition monitoring and machinery protection systems.
This model is configured with a small sensing gap (code “02”), a 1 m integral cable length (code “10”), an industrial 2‑pin ClickLoc connector (code “02”), and an enhanced output option (code “05”), making it suitable for robust industrial installations. The small gap allows high‑resolution measurement, while the sealed housing ensures durability in environments where oil, dust, moisture, and vibration are present.
The proximitor sensor works by establishing an electromagnetic field near the target surface. Changes in this field caused by the proximity of metallic components are detected and converted into an analog voltage signal proportional to displacement. This signal is then used by compatible monitoring modules to evaluate machine condition.
