Description

The Pressure Process Trainer is specifically designed to facilitate the understanding of pressure processes and their control. It comprises a pressure process tank and a pressure transmitter. The tank features an inlet pipe line, which connects to the compressor or pressure supply, as well as an outlet pipe line and a vent pipe line. The outflow is regulated by a control valve, which operates on a 3 to 15 psi pressure signal. To convert the output of the controller (4-20mA) to the signal pressure, a current to pressure (I/P) converter is employed. The process parameter is controlled by a digital indicating controller. These components, along with necessary piping, are mounted on a support frame, making the setup suitable for tabletop placement and access. Furthermore, the controller is connected to a computer via USB for monitoring and controlling the process. User-friendly software will be provided along with the hardware to conduct various sets of experiments.
