Product Overview

The Bently Nevada 2300/20-02 is a compact, high-performance vibration monitor engineered to provide continuous protection for essential machinery that does not require the complexity of a full rack-based system. This module is specifically designed to monitor "Balance of Plant" assets, offering a sophisticated balance of seismic and proximity measurement capabilities. By integrating vibration sensing with speed input, the 2300/20-02 enables time-synchronous processing, allowing for precise detection of mechanical faults. It serves as an autonomous safety layer, equipped with onboard relays to trigger machinery shutdowns and 4-20 mA outputs to stream real-time health data to plant-wide control systems.
