The DAC Process Trainer, Basic, is a realistic, flexible, working fluid
process system designed for hands-on training. The trainer is used to teach
process measurement and control fundamentals relating to flow, pressure,
and level applications.
The trainer allows control loops to be configured employing feedback,
feed-forward, and cascade control methods. Variable demand and supply disturbances
are easily inserted using solenoid valves in combination with metered ball
valves. This arrangement provides step-change disturbances for performing
and verifying controller turning.
The device can be interconnected with other process devices, creating
more complex control schemes. Extremely dynamic and realistic cascade loops,
pressure loops, and three element control loops can be created.
The level tank and piping are transparent, allowing visual inspection
of the process variables. The device contains an integral 24 VDC power supply
and two air regulators with gauges. All instrument electrical power supply
and air sources are conveniently located on the front panel face.
Most importantly, the device can be outfitted with an infinite variety
of controls and instruments in order to address site-specific training needs.
Alternately, a generic instrument and control package can be provided to
create realistic applications within the educational setting. |
