Bently Nevada 1900/55 Fan Monitor

This dedicated monitor provides continuous protection for critical industrial fans and blowers. It tracks vibration, speed, and temperature parameters to identify developing mechanical issues early. The monitor helps prevent catastrophic failures and unplanned downtime in plant operations.

Monitoring Capabilities and Input Configuration

The Bently Nevada 1900/55 accepts signals from proximity probes, accelerometers, or velocity sensors for comprehensive vibration measurement. It continuously monitors fan vibration amplitude and frequency, detecting imbalance, looseness, and bearing wear. The device also tracks rotational speed and temperature inputs for a complete machine health picture. Users can configure alert and danger alarm thresholds to suit specific application requirements.

Technical Specifications

Outputs and System Integration

The monitor provides 4-20 mA analog outputs proportional to measured vibration levels for seamless DCS or PLC integration. It also includes relay outputs for alert and danger conditions, enabling automatic shutdown or alarm annunciation. An optional Modbus communication module allows data exchange with SCADA systems and plant networks. The local LCD display simplifies on-site status checks and parameter adjustments.

Application Use

Industrial fans in power generation, oil and gas, chemical processing, mining, and HVAC systems benefit from this monitor’s protection. It detects developing faults such as rotor imbalance, bearing wear, blade damage, and misalignment. The monitor’s rugged construction suits harsh environments with wide temperature ranges and vibration exposure. Its cost-effective design extends continuous monitoring to previously unprotected fan assets.
