Process Controllers
Process controllers are integral components of industrial automation systems that monitor and control various parameters in manufacturing and industrial processes. These controllers are responsible for regulating variables such as temperature, pressure, flow rate, level, and other process parameters. A process controller receives input signals from sensors and transmitters, compares them to desired setpoints, and adjusts control elements such as valves, actuators, and heaters to maintain optimal process conditions. At SIGMA Surplus, we carry units from Danaher Controls, Dart Controls, and Watlow, along with many more from top OEMs.
