1.Product Overview

Model:3500/25 149369-01

Manufacturer:Bently Nevada

Type:Enhanced Keyphaser Module

Series:Bently Nevada 3500 Series

2.Functional Features

Signal Conversion:Receives input signals from proximity probes or magnetic pickups and converts them into digital keyphaser signals.

Keyphase Mark Alignment:Digital keyphaser signals are used to indicate when a specific mark on a rotating shaft is aligned with the keyphaser sensor.

Multi-channel Input:In normal configuration,the system can accept up to four keyphaser signals and up to eight in paired configuration.

High-precision Monitoring:Provides accurate real-time data to ensure safe and efficient operation of critical machinery.

Enhanced design:with extended signal processing capabilities and retains backward compatibility with existing key phaser modules.

Asset management data reporting:supports field-upgradeable firmware and provides asset management data reporting.
