Key Features
Experiments
Construction and Design
The Level Control Trainer, Prozessi PX 16, is built around a supply water tank fitted with a pump for water circulation. The level transmitter is fitted on a transparent process tank, and the pneumatic control valve, operated through an I/P converter, adjusts water flow into the tank. These units, along with the necessary piping, are mounted on a support housing designed for tabletop mounting. This construction supports the Level 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 Level Control Trainer help students understand?
A: It is designed for understanding the basic principles of level control using a level transmitter, pneumatic control valve, and transparent process tank.
Q2: How is level measured in this trainer?
A: Level is measured using an electronic, two wire level transmitter fitted on the transparent process tank, with a range of 0 to 250 mm.
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.
