DAC Worldwide’s 3-Variable Process Control Training System (601-000EG) 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 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.

Take Control of Process Control Training Using Real-World Components

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. While this system can be outfitted with instruments of any brand, the system includes an Endress + Hauser instrument & control package featuring two PID controllers, differential pressure transmitter, I/P converter panel, gauge pressure transmitter, digital multimeter, bubbler assembly, U-tube, manometer, square root extractor, and pressure switch.

For even more training options, this system can be purchased as the 3-Variable Process Control Training System Plus (601-PACEH), which includes everything that the 601-000EH offers plus a standard calibration test and equipment package (600-006A), PLC control interface panel (600-007), AC variable speed drive (600-010), and economy ultrasonic level transmitter (601-022).
