Bently Nevada 103928-02 Keyphasor Signal Processing Board

Quick Overview

The 103928-02 is a high-performance Keyphasor® Input Board for the Bently Nevada 3500 Machinery Protection System. It acts as the synchronization hub for the entire rack, converting analog pulses from proximity probes or magnetic pickups into digital timing signals. 

Technical Data

• Signal Sources: Proximity Probes, Magnetic Pickups

• Digital Outputs: Speed, Vibration Amplitude, Phase

• Communication: Ethernet Link to Data Manager

• Data Handling: 2 Independent Startup/Shutdown Buffers

• Recovery: Immediate Power-Loss Recovery logic

• Dimensions: 16 x 12 x 10 inches (approx. boxed size)

Key Features

• Precision Signal Conversion: Transforms raw analog "once-per-turn" pulses into clean digital signals, ensuring zero-lag synchronization for the entire 3500 rack.

• Multi-Parameter Measurement: Beyond simple speed tracking, it provides the phase reference required to calculate shaft orbits and vector monitoring.

• High-Resolution Diagnostics: Delivers static, orbit, and spectrum data with high resolution, enabling engineers to identify specific mechanical faults like imbalance or misalignment.

• Dual Event Buffers: Equipped with two independent buffers specifically designed to capture critical data during machine startup and shutdown cycles.

• Seamless Network Integration: Features a dedicated Ethernet interface for efficient data transmission to the System Data Manager or host software.
