Description
Bently Nevada 3500/25-02-01-CN Enhanced Keyphasor Module
Bently Nevada 3500/25-02-01-CN is a half-height dual-channel enhanced keyphasor module exclusively designed for the Bently Nevada 3500 series machinery protection monitoring rack. This Bently Nevada 3500/25-02-01-CN module converts analog signals from proximity probes and magnetic pickups into precise digital keyphasor pulses, providing critical angular timing references for rotational speed measurement, phase analysis and vibration fault diagnosis of high-speed rotating equipment. It serves as the core timing signal source for all monitoring cards inside the 3500 frame and is widely applied to safety-critical rotating machinery monitoring systems across heavy process industries.
