Description
Overview
The Bently Nevada 330850‑91‑00 is a 25 mm Proximitor Sensor engineered for long‑range, high‑accuracy displacement and vibration monitoring in large rotating machinery. As part of the 3300 XL Proximity Transducer System, it delivers stable linearity, excellent temperature performance, and dependable operation in demanding industrial environments.
Design and Construction
This sensor conditions the signal from a compatible 25 mm proximity probe and provides a precise voltage output proportional to the distance between the probe tip and the monitored conductive surface. It supports both static shaft position and dynamic vibration measurements, making it suitable for machinery protection and predictive maintenance programs.
The 330850‑91‑00 features a system length of 9.0 m (29.5 ft), enabling flexible installation in large machines or control panels with extended cable routing requirements. Its DIN‑rail mounting design supports high‑density panel layouts and simplifies integration into existing monitoring architectures.
Compact dimensions and lightweight construction allow easy handling, while the rugged housing ensures long‑term reliability in harsh industrial environments such as mining, metals processing, power generation, and renewable energy facilities.
