Why Install The PID Controller In The Final Control Element?
• Reduces lag time between the measuring element, controller and control valve. • Increases process efficiency through faster valve response. • Quicker process start up. • Microcontroller function allows for greater resolution and more variables to customize the valve to the process. • Setpoint control either locally at the valve or from a PLC. • Inexpensive to install, less wiring. • Cost approximately the same as the traditional valve, actuator and positioner.
