Key Features
Experiments
Construction and Design
The Pressure Control Trainer, Prozessi PX 17 Model 314A, is built around a pressure vessel fitted with a pneumatic control valve. The pressure transmitter senses pressure in the vessel, and the control valve, fitted at the outlet of the pressure tank and operated through an I/P converter, regulates the process. These units, along with the necessary piping, are mounted on a support housing designed for tabletop mounting. This construction supports the pressure control trainer in both manual and SCADA controlled modes.
Software
Specially developed SCADA software is provided which helps in learning the principles of control. Different experiments can easily be selected and studied. The software is easy to use, flexible, and includes features like data access, trend plots, data logging, printing, and data export.
Scope of Delivery
Required for Operation
Q1: What does the Pressure Control Trainer help students understand?
A: It is designed for understanding the basic principles of pressure control using a pressure vessel, pressure transmitter, and pneumatic control valve.
Q2: How is pressure measured in this trainer?
A: Pressure is measured using a two wire pressure transmitter with a range of 0 to 5 bar and an output of 4 to 20 mA.
Q3: How is the control valve operated?
A: The pneumatic control valve is operated through an I/P converter, which converts the 4 to 20 mA controller output into a 3 to 15 psig pneumatic signal.
Q4: Can the trainer be monitored remotely?
A: Yes, the controller can be connected to a computer through an Ethernet port for monitoring the process in SCADA mode.
Q5: What software is provided with the trainer?
A: A specially developed SCADA software is provided, offering data access, trend plots, data logging, printing, and data export.
