Collection: Bently Nevada 3500/25 Keyphasor Module

The Bently Nevada 3500/25 Enhanced Keyphasor Module is a half-height card for the 3500 Monitoring System that converts proximity or magnetic pickup inputs into a precise once-per-turn Keyphasor signal, providing the critical timing reference needed to measure shaft speed, vibration phase, and vector parameters. Designed with expanded signal processing capabilities and full backward compatibility, it enables early detection of faults like imbalance and misalignment, ensuring reliable protection for turbines, compressors, and other high-speed rotating equipment.
