Bently Nevada 330104‑00‑03‑90‑11‑00 — Detailed Technical Overview
1. Product Introduction
The Bently Nevada 330104‑00‑03‑90‑11‑00 is a high-performance eddy-current proximity sensor designed for precise monitoring of shaft displacement and vibration in large rotating machinery. This model is part of the 3300 XL Proximitor Sensor Series, which has a long-standing reputation in industrial machinery protection and condition monitoring.
This configuration features a 3 mm sensing gap (code “03”), a 90 m integral cable (code “90”), and an 11‑pin industrial connector (code “11”), providing secure and reliable connections for complex installations. Its extended cable length is suitable for large-scale plants or applications where the sensor must be installed at a significant distance from monitoring modules.
The sensor operates on eddy-current technology, converting variations in the electromagnetic field caused by the proximity of a conductive target, typically a rotating shaft, into an analog voltage output. This allows operators to track real-time displacement, vibration amplitude, and machine condition without physical contact, ensuring minimal maintenance and high reliability.
