A Process can be defined as: "A series of actions, changes, or functions bringing about a result"
Actions, changes and functions performed in Process Equipment are for the most part electrically controlled and based on Process measurement set-points which are electrically monitored. Burners, furnaces and vessels may all be sized correctly, but if there is poor control the process will not give you the expected output
Temperature, Conductivity, Pressure, Time, Density, PH Level, Moisture, U-V & Infrafred Light Sensing, Flow and Electromagnetic Position Detection are a few of the many types of measurement points (Inputs) required to keep track of a process
Valves, Motors, Ignitors, Indication and Alarm functions are devices (Outputs) typically found in Burner and Process Control systems, each being electrically operated based on one or more measurement points noted above
