Bently Nevada 1900/55-01-01-01-00 Fan Monitor

Product Introduction

The Bently Nevada 1900/55-01-01-01-00 Fan Monitor is a dedicated vibration monitoring device designed for continuous condition monitoring of fans and blowers in industrial environments. It is part of the renowned Bently Nevada 1900 Series, specifically engineered for stand-alone protection of rotating machinery. This model delivers real-time vibration analysis to prevent unexpected failures, reduce downtime, and enhance machinery reliability.

The unit integrates with proximity probes or accelerometers to measure dynamic vibration levels and provides early detection of potential issues like unbalance, misalignment, looseness, and bearing degradation. It features configurable alarm thresholds, relay outputs for trip or warning conditions, and compatibility with Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC) for seamless integration into plant-wide monitoring systems.

Designed for harsh industrial conditions, the monitor withstands temperature extremes, vibration, and contamination such as dust and moisture. It is ideal for critical equipment where failure could result in costly shutdowns or safety hazards.
