Condition monitoring is all about identifying problems before failure occurs in order to prevent costly production stops. Typical equipment that is monitored includes high- and low voltage installations, turbines, compressors and other electrical and mechanical equipment.
Sometimes processes need to be monitored because an anomaly can cause dangerous situations. Flares, that often have a flame that is not visible to the naked eye, need to be monitored to see if they are effectively burning the produced gasses. A steel ladle that suddenly breaks open can create dangerous situations.
