Optimisation relative to your space requirement
Maybe you're restricted in the amount of space you have available but you want each of your training workstations to offer a high level of complexity. If so then the Compact Workstation with four integrated closed-loop control systems is the solution for you. As shown in the flow chart, the individual control systems can be activated by simply repositioning the ball valves. The flexible piping system enables you to change the flow scheme or integrate other components quickly and easily.
Function
The four control systems in the Compact Workstation can be operated individually.
The level and flow rate control systems can be structured as a cascade control system through the addition of an appropriate controller.
The layout of the sensors and servo drives permits experimentation with both continuous (e.g. P, I, PI, PID) and discontinuous action controller types (e.g. 2-point controllers). The pump can either be controlled directly or operated in controlled-speed mode.
The manipulated variable of the controller in the flow rate and pressure control systems can alternatively act upon a proportional directional control valve. A ball valve with pneumatic drive is built into the return between the high-level container and the lower reservoir. The pneumatic drive can be used to simulate a “load” for switching on a disturbance in the level control system or as an on-off valve for emergency switch-off.
Piping and instrument flow chart
An important part of project work in process engineering is developing a piping and instrument flow chart. A piping and instrument flow chart explains the electrical, measuring and control technology functions using measuring points and final control elements. The measurement variable or another input variable, its processing, its direction of action and directional specifications and positions should follow from the chart.
Mounting frame
Can be equipped with accessories for controllers, control unit and/or touchpanel. The activation and/or control devices can be replaced in just seconds.
Pneumatic drive
With ball valve and signal box. Training aims: Design and application areas of various metering and shut-off devices when controlling the flow of liquids.
Intelligent in the field – closed-loop control with the CPX/FEC valve terminal and the FED 120 touchpanel
The Festo Front End Controller with integrated web server and Ethernet interface is ideally suited to current communication tasks.
