مقدمة المنتج
The Bently Nevada 3500/25-01-01-00 Enhanced Keyphasor Module is a vital component من the renowned 3500 Series machinery protection system. This module serves as the primary phase reference source for monitoring rotating machinery, providing precise timing signals needed to analyze shaft vibration and position.
This Keyphasor module processes input from magnetic pickups or proximity probes to generate a clean, TTL-compatible pulse that marks the angular position من the shaft. These pulses synchronize vibration data acquisition and enable advanced diagnostic tools such as orbit plots, Bode plots, and rotor balancing.
The “Enhanced” designation reflects improvements in signal conditioning, noise immوحدةy, and integration capability, making it well suited for high-speed turbines, compressors, and motors in demanding industrial environments.
