zentrak Acoustic Monitoring Sensor
Allocation of measurement data to the correct carriage and wheelsets.
Monitoring of the health of bearings during train operations provides a valuable source of information for optimizing maintenance and overhaul intervals of wheelsets.
The function Acoustic Monitoring Sensor (AMS) is a highly sensitive measurement system that collects the acoustic signature of each bearing of a passing train. Defects associated with the individual components of both tapered and cylindrical roller bearings are detected at an early stage and trends for each monitored bearing are provided. Alarms are generated at user-defined tolerance levels, which supports efficient wheelset maintenance programs.
In addition to bearing defects, future phases of development will identify wheel defects, locomotive engine defects and locomotive drive train defects.
