Introduction

The Bently Nevada 3500/25M Enhanced Keyphasor Module is a refined phase-reference and timing module developed for the 3500 Series machinery protection and condition monitoring system. From a machinery diagnostics and reliability engineering perspective, this module provides the critical synchronization point required for accurate rotor speed, phase, and angular position analysis.

By converting tachometer and probe signals into precise Keyphasor references, the 3500/25M enables advanced vibration diagnostics and fault interpretation without acting as a standalone measurement device. It is an essential component in high-integrity monitoring architectures for rotating equipment.
