Two additional modules on PID controllers and control valves add to the instrumentation technician’s knowledge of control loops. Further study of process control terminology, controller indicators, adjustments and options and controller types is followed by an introduction to the proportional, integral and derivative algorithms used to tune controllers to a process. Valve bodies, valve actuators and valve positioners are studied as the primary choice of final control element encountered in industry. Other final control elements like variable speed pumps, motors and fans, as well as dampers and feeders are introduced. Auxiliary equipment like regulators and solenoid valves are covered as are relief or safety valves.
