This device is a multifunctional experimental device integrating automatic instrument technology, computer technology, communication technology and automatic control technology. The system includes flow rate, temperature, liquid level and other thermal parameters, which can achieve system parameter measurement, single loop control, cascade control, feedforward control, ratio control and other control forms. The experimental device can not only serve as an experimental device for undergraduate, junior college and higher vocational course of process control, but also provide physical simulation objects and implementation means for graduate students and scientific researchers in the research of complex control system and advanced control system. It can also be used as an experimental means to learn fieldbus process control. It can meet the experimental teaching of "instrument test and control experiment", "process control", "fieldbus control system", "automatic instrument" and other courses. This experimental device is composed of process control system and process control object. It can complete the process control system related experiments composed of PLC and field bus, instrument process control experiment, DCS process control experiment, and configure the monitoring terminal.
