Bently Nevada 330104‑00‑03‑05‑11‑05 — Detailed Product Overview
1. Product Introduction
The Bently Nevada 330104‑00‑03‑05‑11‑05 is an industrial eddy‑current proximitor sensor designed for precise, non-contact measurement of shaft vibration and displacement. It belongs to the 3300 XL Proximitor Sensor Series, a globally recognized line of sensors used for machinery protection, condition monitoring, and predictive maintenance.
This particular model features a 3 mm nominal sensing gap (code “03”), a 5 m integral cable length (code “05”), and an industrial connector (code “11”) with enhanced environmental sealing (code “05”). The enhanced environmental sealing provides extra protection for applications exposed to moisture, oil, and dust.
The sensor works by detecting changes in a magnetic field caused by a conductive target (typically a rotating shaft) and converting these changes into a proportional analog voltage signal. This allows monitoring systems to continuously track radial or axial displacement, detect misalignment, imbalance, or vibration issues, and trigger alarms if limits are exceeded.
The 330104‑00‑03‑05‑11‑05 sensor is engineered for demanding industrial environments, including high vibration, temperature fluctuations, and exposure to lubricants or particulates. Its robust design makes it suitable for turbines, pumps, compressors, and other critical rotating machinery.
