Product: BENTLY 3500/25-01-05-01 – Enhanced Dual Channel Keyphasor Module

Bently Nevada 3500/25-01-05-01 TSI Enhanced Keyphasor Card for Rotational Speed Measurement and Vibration Phase Reference

3500/25-01-05-01 is a half-height enhanced dual-channel Keyphasor module belonging to the Bently Nevada 3500 TSI machinery monitoring system. The digit suffix definition: 01 represents standard safety certification specification, 05 stands for galvanically isolated I/O interface configuration, and the last 01 refers to factory standard firmware revision. This module receives pulse signals from eddy current probes or magnetic pickup keyphasor sensors, converts analog waveform signals into standard digital keyphasor pulses. It supplies rotational speed value and 1X phase reference signals to vibration monitoring boards within the rack, serving as the core reference component for rotor vibration vector analysis, rotational speed supervision, overspeed protection and fault spectrum analysis. Cooperating with 3500/40, 3500/42 and other monitor modules, it realizes full-scale condition monitoring and protection logic operation for rotary equipment.
