About the data 

Remote monitoring

A single Bergen medium-speed engine can have more than 200 sensors transmitting a vast amount of data that measures all aspects of an engine’s health and performance at any given moment.

Data analytics, A.I and deep learning combine to give you real-time insights into your equipment using our Equipment Health Monitoring system (EHM).
