Bently Nevada 149369-01 126398-01 Enhanced Keyphasor Module is a half-height, dual-channel module that receives input signals from proximity probes or magnetic sensors and converts them into digital keyphase signals to indicate when the keyphase mark on the shaft coincides with the keyphase sensor.
Keyphase signals can be provided to monitoring modules in the 3500 rack to enable monitoring and protection of rotating equipment, providing critical machine information to operators and maintenance personnel.
This product is widely applied in industries such as power, petrochemicals, natural gas transportation, and metallurgical manufacturing. It is an essential component for achieving predictive maintenance and fault diagnosis of rotating machinery.
