Bently Nevada 3500/25-01-03-01 Enhanced Keyphasor Module
Description
The Bently Nevada 3500/25-01-03-01 is a half-height, two-channel Enhanced Keyphasor Module for the 3500 Machinery Protection System that receives input signals from proximity probes or magnetic pickups and converts them to digital Keyphasor signals indicating when the Keyphasor mark on the shaft coincides with the transducer.
Features
Half-height, two-channel module with expanded signal processing capabilities
Provides Keyphasor and speed reference signals for rotor vibration monitoring and protection
Field-upgradeable firmware and asset management data reporting
Maintains downward compatibility with existing Keyphasor modules
Up to four Keyphasor modules per 3500 rack (normal configuration)
