Process Control Simulator ( Advance PID Controller ) 4042

Categories: Control Engineering

4042-1ADTRON’s Process Control Simulator ( Advance PID Controller ) is an excellent learning tool for the students to learn the concept of Proportional,  Integral, Derivative and its combinations using simulated approach. The unit consists of an Input Disturbance generator, PID Controller, different types of processes, non—linear characteristics generator, indicating meters, etc all housed in an elegant metal cabinet with a well spread intelligently designed circuit layout on the front panel. A comprehensive Instruction manual complete with theory and operation details is provided.
