The Evolution of Automatic Control Systems in Process Control Fifty years ago, process control relied on the 3 to 15 psi pneumatic signal standard, forming the first generation of process control systems known as the Pneumatic Control System (PCS). As technology advanced, the second generation…

The development of automatic control systems in process control has evolved significantly over the past five decades. Initially, in the mid-20th century, process control relied on a 3 to 15 psi pneumatic signal standard, forming the first generation of process control systems—known as th…
