EMR vs MPC Comparison

Founded in 1890 as the first manufacturer of electric fans in North America, Emerson Electric has become a leading industrial automation player through the acquisition of established brands. Emerson organizes its business into seven segments that sell a wide range of automation software, power tools, and automation hardware such as valves, gauges, and switches. In recent years, Emerson divested its climate technology and consumer businesses to become more of a pure-play industrial automation company. The automation of a factory is an enticing long-term proposition for manufacturers, helping reduce accident rates and raise uptime and productivity.
