Bently Nevada 3500/25 149369-01 Machinery Condition Monitoring

The Bently Nevada 3500/25 149369-01 is a half-height, two-channel Enhanced Keyphasor Module for the 3500 Series Machinery Protection System. Its core function is to receive input signals from proximity probes or magnetic pickups and convert them into precise digital Keyphasor signals. These signals indicate exactly when a Keyphasor mark on a rotating shaft passes the sensor, providing a critical timing reference used to measure rotational speed, vibration phase, and other vector parameters.
