This online course covers the function of basic devices for measuring and controlling different kinds of variables in process control. Introduces closed-loop control and PID functions. Introduces maintenance of analog and digital devices and programmable logic controllers (PLCs). ISA and SAMA instrumentation symbols and interpretation and use of process diagrams are covered. This course has no prerequisites. Introduction to Process Control is available in online technical training and course manual formats.
TPC Training Systems is authorized by IACET to offer 0.6 CEUs for this program.
