Bently Nevada 1900/55 Fan Monitor

Overview

The 1900/55 Fan Monitor is part of GE’s Bently Nevada 1900 series, offering compact, standalone machinery protection solutions. Unlike rack‑based systems, the 1900/55 is tailored for fans and blowers, where vibration monitoring is essential to maintain performance and prevent costly downtime.

It excels at handling low‑frequency vibration signals, common in fan gearboxes and large rotating assemblies. The monitor integrates easily into existing control systems, making it suitable for both new installations and retrofits.

Technical Data

Typical Applications

• Power generation: Monitoring cooling fans and blowers in turbine halls.

• Oil & gas: Protecting large process fans and air handling units.

• Chemical plants: Ensuring reliable operation of agitators and exhaust fans.

• Water treatment facilities: Monitoring aeration blowers and ventilation fans.

• Manufacturing automation: Detecting vibration issues in conveyor fans and dust collectors.

Example: In a steel plant, the 1900/55 Fan Monitor can detect early signs of imbalance or bearing wear in large cooling fans, allowing maintenance teams to intervene before production is disrupted.
