Machine monitoring technologies, for both main and auxiliary machines, have evolved significantly over the last few years, incorporating the use of artificial intelligence and the internet. The use of automatic diagnostics-based systems and remote diagnostics eliminates common problems encountered when monitoring critical machines in plants lacking local analysts.  

Critical machines that can be monitored in industrial plants include: steam and gas turbines, centrifugal pumps, fans, electric motors, rotary, screw, and alternative compressors, agitators and mixers, mills and rotary kilns, gearboxes, centrifuges, cooling towers, diesel engines and engine generators.
