Product Overview
The Bently Nevada 3500/25 Enhanced Keyphasor Module (149369-01) together with the Keyphasor I/O Module with External Terminations (126648-01) provides a reliable two-channel Keyphasor interface for the 3500 Machinery Protection System. It converts input signals from proximity probes or magnetic pickups into precise digital pulses. These pulses represent once-per-turn or multiple-event-per-turn shaft positions, enabling accurate speed, phase, and vibration measurements. The design is fully backward-compatible, ensuring smooth upgrades from earlier modules, while the external termination I/O simplifies wiring and maintenance.
