Bently Nevada 3500/25 Enhanced Keyphasor Module

Description

3500/25 Enhanced Keyphasor Module
Description:The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module designed to provide Keyphasor signals to monitor modules in a 3500 rack. It receives input signals from proximity probes or magnetic pickups, converting them into digital Keyphasor signals. These signals indicate the alignment of the Keyphasor mark on the shaft with the Keyphasor transducer. The module supports up to four Keyphasor signals in a normal configuration and up to eight in a paired configuration.
