Description
Process Trainer is an educational package that mimics industrial process engineering. The fully integrated, self-contained teaching apparatus gives a comprehensive range of process control experiments, from basic to advanced. Using water as the working fl uid, the equipment allows safe, practical experiments on control of fl ow, liquid level, temperature and pressure. Students can study each of these separately or in combinations. The equipment consists of an experiment module, a control module and software. The experiment module includes all the essential parts to allow students to create process control systems. The main part is the process vessel, with a stirrer, a temperature sensor, level and pressure sensors, a heat exchanger and vent valve. It also includes two loops, linked by the heat exchanger in the process vessel. One loop is the heating loop with pump, heater tank and heater. The other loop is a process and cooling loop with pump, cooler, fan, valves and reservoir. The control module links to the experiment module to provide access to the connections of each part on the experiment module. It includes a clear mimic diagram with switches and controls to allow manual control of pump speed, cooler-fan speed, heater power and stirrer. It also includes sockets and a built-in computer interface. This allows the user to link each part of the experiment module to a suitable computer (not included) for remote control and data acquisition. Supplied with the equipment is Control Software for supervisory control of the and data acquisition. You need a suitable computer to use the software.
