Product Name:THFCS-E1 Profibus Process Control Objects Lab System
Product Series:Process Control & Instruments Training Series
Product Introduction

Technical Description
    The THFCS-E1 objects system is composed of stainless steel frame, organic glass tanks (upper, middle, lower), stainless steel boiler, spiral tube for heat exchange, stainless steel magnetic force driving pump, stainless steel pipe, and manual valve, etc. It is designed for courses of "Automatic Control Theory", "Process Control", "Automation Instruments", and "Sensors Detection & Conversion Technology" in college and vocational schools. Additionally, the available objects system facilitates researching on complex control system, smart control system, etc.
    Features:
    Controlled parameters covering flow, pressure, liquid level, temperature;
    Actuators including electric valves, and frequency converter;
    Available step disturbance generated by adjusting the setting of regulator, as well as other kinds of disturbances formed using solenoid valve and manual valve;
    Several kinds of control circuits formed by a controlled parameter, electric circuits with different techniques, and different kinds of power sources and actuators;
    Ability of performing exercises of multivariable control system and specially process control system.
