Description

The Interacting and Non-Interacting Process Trainer is designed to understand the elements of second order interacting and non-interacting process and its control. It consists of three level process tanks and two- level transmitter with necessary drain valve arrangements. It is designed to operate the setup in interacting mode or in non-interacting mode. The setup can also be used to estimate the second order model of interacting and non-interacting tank processes. The control algorithm works by measuring the second tank level and controlling the first tank inflow. A control valve operates on a 3 to 15 psi pressure signal is used to regulate the
inflow. A current to pressure (I/P) converter is used to convert the output of the controller (4-20mA) to the signal pressure. The process parameter can be accessed and controlled by a data acquisition unit. These units along with necessary piping are fitted on the support frame. The setup is designed for tabletop placement and access. User friendly software will be supplied along with the hardware to perform different set of experiments.
