Bently Nevada 3500/25-01-01-01 149369-01 Enhanced Keyphasor Module

Overview

The 3500/25-01-01-01 Enhanced Keyphasor Module by Bently Nevada is part of the 3500 Machinery Condition Monitoring system. This two-channel, half-height module plays a vital role in machinery protection by transmitting Keyphasor signals to other modules in a 3500 rack.

Key Features and Functionality

• The Keyphasor Module detects alignment between the Keyphasor mark on the shaft and the Keyphasor transducer.
• It uses magnetic pickups or proximity probes to detect alignment and convert the input signals into digital Keyphasor outputs.
• In a typical setup, the 3500 Machinery Protection System can accommodate up to four Keyphasor signals.
• When paired, it can support up to eight Keyphasor signals for increased flexibility.

Enhanced Capabilities

The 3500/25-01-01-01 Enhanced Keyphasor Module improves upon the legacy PWA 125792-01 Keyphasor module by offering better signal processing capabilities. It ensures full backward compatibility with existing systems while providing enhanced performance.
