The workstation houses the electrical and the pneumatic units, as well as the other components used in the experiments. A controller (sold separately) is required to have a fully functional system. Because air process components and instrumentation can be mounted on the same workstation, this system is compact in size. Although some of the system components are pre-configured, the installation, wiring, and configuration of many devices must be done by the learners as part of the course. The workstation is equipped with wiring ducts to organize wires and features a handy pull-out work surface. Lockable, swiveling casters allow movement of the workstation. Various optional components are available to customize the workstation. Main Learning Objectives – Pressure measurement with a smart transmitter – Flow measurement using a rotameter and a smart transmitter – Tuning a pressure control loop using Ziegler-Nichols and ultimate-cycle methods – Tuning a flow control loop with the trial-and-error method – Troubleshooting a process or control system Calibration Instrumentation An accurate calibration device is an essential addition to allow calibration and maintenance of the transmitters, current-to-pressure converter, gauges, and control valves. Fault Insertion There are three different methods to insert faults and develop troubleshooting skills: by accessing the component’s fault panel, by changing the calibration parameters of a device from the instructor’s computer, or by remotely modifying the state of I/O relays on a PLC from a computer or from a touch screen terminal. Smart Devices A few components feature a transmitter that can communicate via the HART communication protocol, which enables communication between devices by superimposing digital signals on top of the existing 4-20 mA outputs. Most of these devices can be configured via their alphanumeric display and/or push-buttons, or via a HART software configurator (strongly suggested).
