3500/25 is an Enhanced Keyphasor Module developed by Bently Nevada. It is a half-height, two-channel module used to deliver Keyphasor signals to the monitor modules in a 3500 rack. When the Keyphasor mark on the shaft aligns with the Keyphasor transducer, the module detects the alignment using magnetic pickups or proximity probes and converts the input signals into digital Keyphasor signals.

3500/25 Functional Description
For regular setup, the 3500 Machinery Protection System can accept up to four Keyphasor signals, and for paired configuration, it can accept up to eight.
A spinning shaft or gear's once-per-turn or multiple-event-per-turn pulse known as a keyphasor signal can be used to detect timing precisely.
As a result, shaft rotative speed and vector characteristics like 1X vibration amplitude and Phase can be measured by 3500 monitor modules and external diagnostic tools.
