Plant historians: Historians provide data to gain insights and improve operation

摘要

Plant historians became popular in process plants in the 1980s. More recently they are being used broadly throughout industry to improve operations, identify problems, and find opportunities for enhancement. An early forerunner of historians were electromechanical pen-and-paper chart recorders. They produced a graph of one or more measured values over a period of time for analysis and a permanent record of critical information.
