Bently Nevada Keyphasor Transducer

Core Performance & Industrial Application

The Bently Nevada Keyphasor is a special proximity transducer used as phase reference for rotating machinery monitoring.

It detects the notch or keyway on the rotating shaft and outputs one pulse per revolution.

It provides precise timing signal to calculate rotational speed, 1X vibration amplitude and phase angle.

It works with Bently Nevada 3500/25 Keyphasor module and TSI monitoring rack for machinery protection.

It supports synchronous vibration analysis, rotor dynamic diagnosis and fault identification for high-speed rotating equipment.

It is widely used for steam turbine, compressor and large pump condition monitoring spare replacement.
