Description

The Cascade Process Trainer is designed to understand the elements of a cascade process technique and its control. It consists of two loops namely the flow loop (Inner or Slave loop) and the level loop (Outer or Master loop). The output of the primary (Level) loop will go as the set point of the secondary (Flow) loop. The setup is designed to perform Level, Flow and Cascade experiments. The setup consists of a process tank fitted with a level transmitter, an orifice to measure flow with a differential pressure transmitter and necessary drain
valve arrangements. The inlet flow to the process tank is controlled by a control valve which operates on a 3 to 15 psi pressure signal. A current to pressure (I/P) converter is used to convert the output of the controller (4- 20mA) to the signal pressure. The process parameters are communicated to the personal computer using ACE 2007 WiFI DAQ. 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.
