Bently Nevada 1900/55 Fan Monitor

Product Introduction

The Bently Nevada 1900/55 Fan Monitor is an advanced industrial instrument designed for precise monitoring of fans, blowers, and auxiliary rotating equipment in critical process systems. It continuously tracks vibration and shaft movement, providing operators with real-time data to detect mechanical issues such as imbalance, misalignment, bearing wear, and rotor looseness.

Engineered for harsh industrial environments, the 1900/55 Fan Monitor delivers high-resolution measurements and reliable performance even in conditions of extreme vibration, temperature, dust, and moisture. It is fully compatible with Bently Nevada proximity probes, vibration sensors, and other standard instrumentation.

The monitor integrates seamlessly with distributed control systems (DCS) and programmable logic controllers (PLC), supporting predictive maintenance and reducing unplanned downtime. Configurable alarm thresholds, visual indicators, and relay outputs allow precise machinery protection while enabling flexible system integration.
