Overview

The Bently Nevada 87890-01 System Monitor is a key module within the 3500 Series Machinery Protection System, designed to provide centralized control, communication, and diagnostics for all monitoring modules installed in the rack. It acts as the “brain” of the system, coordinating data acquisition, alarm processing, and communication with plant control systems.

Engineered to meet API 670 standards, the 87890-01 ensures reliable machinery protection in demanding industrial environments such as power generation, oil and gas, petrochemical, and heavy manufacturing. Its robust design and advanced functionality make it essential for facilities requiring continuous monitoring of turbines, compressors, pumps, and motors.

Technical Data

Typical Applications

• Turbine monitoring systems in power plants, coordinating vibration and temperature monitoring modules.

• Compressor and pump monitoring in petrochemical facilities, ensuring safe operation of critical rotating equipment.

• Oil and gas refineries, where centralized monitoring prevents catastrophic failures.

• Heavy manufacturing plants, supporting condition monitoring for motors, gearboxes, and production machinery.

For example, in a gas turbine installation, the 87890-01 System Monitor processes data from multiple modules, communicates alarms to the plant control system, and ensures operators receive real-time diagnostics for predictive maintenance.
