DAC Worldwide’s 3-Variable Process Control Training System (601-000) is a working, large-scale, fluid process system allowing for hands-on training relating to the measurement and control of process variables including level, pressure, and flow. The device allows for the creation of simple and advanced process loops using common, industrial-quality instruments and controllers. An "open architecture" allows for the integration of alternate instrumentation as needed to address local training needs. Variable demand and supply disturbances can be inserted using solenoid valves in combination with metered ball valves.
The device includes the capability of establishing cascade, feedforward, feedback, feedback split range, ratio, and three-element control schemes. Clear PVC piping allows the student to see process changes based on control parameters or intentional disturbances. Quick-disconnects are provided allowing the training aid to be connected to other similar units or a temperature process trainer, facilitating more complex process systems.
The trainer can be configured to create one complex process loop, accommodating two students, which addresses pressure, level, and flow. Alternately, the device can be outfitted to address each of these three variables individually. Standard, user-supplied, or user-specified instruments of any brand can be easily installed, either on a mounting stanchion or on a built-in, 19-in. instrument rack.
