Process Trainer, Advanced

#603

The DAC Process Trainer, Advanced, is a self-contained, realistic, working fluid process designed for hands-on training. The training device is used to teach process measurement and control fundamentals involving flow, pressure, level, and temperature applications. The trainer allows control loops to be configured employing feedback, feed-forward, cascade, split range, ratio, and three-element control methods. Variable demand and supply disturbances can be inserted using solenoid valves in combination with metered ball valves. This arrangement provides step-change disturbances for performing and verifying controller tuning. Extremely dynamic and realistic cascade loops, pressure loops, and three-element control loops can be created. The temperature measurement and control variable uses a dynamic shell and tube heat exchanger process. Common tap water is used as the cooling water source. All pneumatic control valves are compatible with standard industry valve positioners. The level tanks and piping systems are transparent, allowing visual inspection of the process variables. The front panel-mounted controls provide on/off control of all trainer components along with pilot lights showing component status. The device contains an integral 24 VDC power supply and two air regulators with gauges. All instrument electrical power supply and air supply sources are conveniently located on the front control panel.
