Product Details
The 3500/25-02-03-00 Enhanced Keyphasor Module is a half-height, two-channel module designed for the Bently Nevada 3500 Machinery Protection System. It receives input signals from proximity transducers or magnetic pickups and converts them into digital keyphasor pulses used by monitor modules for speed measurement, vector calculations, and phase-related vibration analysis. This specific configuration includes internal intrinsic safety barriers with agency approvals.
Functional Operation and Inputs
The module accepts up to two transducer inputs, processing signals to provide speed and phase reference information to other modules in the 3500 rack via the proprietary rack backplane. Each channel can be independently programmed to accept signals from proximity probe transducers or magnetic pickups. It features internal processing capability to filter noise and condition input waveforms into square-wave signals suitable for high-speed machinery monitoring.
