Overview

The Bently Nevada 3300/03-01-03 System Monitor is a vital component in the 3300 Series rack-based machinery protection architecture. Installed in the rack’s dedicated system monitor slot, it performs four essential functions:

• Distributes power to all rack modules

• Manages Keyphasor® signal termination and conditioning

• Coordinates alarm logic

• Provides system inhibit and alarm reset capabilities

This model includes both Serial Data Interface (SDI) and Dynamic Data Interface (DDI), ensuring seamless integration with external systems and diagnostic software. It also supports alarm setpoint adjustments and system diagnostics, making it a critical tool for reliability and maintenance engineers.

For example, in a turbine monitoring configuration, the 3300/03-01-03 ensures synchronized Keyphasor® signals across vibration monitors and coordinates alarm responses during abnormal machine conditions.

Technical Data

Typical Applications

• Centralized control in turbine and compressor monitoring racks
